bikefix breakdown

Our apologies to anyone who came by recently for their daily bikefix and saw this nonsense. If you're reading this now, that's because we've fixed it! Of course, because it took ages to figure out how to fix it, there'll be no second post this week. You'll have to make do with a "Merry Christmas!" instead. Back next week...

bikefix Initial Review: Exposure Lights Diablo lightset

For the shortest day of the year, we have a review of Exposure's very cool (and super light) 700 lumen Diablo lightset. From the UK, where short (though relatively mild) winter days and a strong culture of 24-hour racing make night riding extremely popular, comes what is essentially a bulked-up version of the company's extremely popular Joystick, the 102g (plus mounting hardware) Diablo is shaped like a small handheld flashlight. Like the 240 lumen Joystick (see our overview of the entire range here), the Diablo mounts to the helmet by way of a readily adjustable ball and socket mount or to the bars with the company's very solid but low-profile forged handlebar mount. In keeping with the Exposure's Cable-Free Design (CFD) philosophy, the light's primary power source is an internal lithium-ion battery- though additional batteries and accessories can be added using the light's rear SPT (Smart Port Technology) port.

We first had a look at Exposure's lights back in November, when US distributor Ibex Sports sent out the full range for us to play with. When it came time to send the lights home, I liked enough about the Diablo to buy it along with a 3-cell auxiliary battery for commuting, night riding, and 24-hour racing. Shorter than a Mini Mag Lite and barbell shaped, the Diablo uses a single Seoul Semiconductor P7 emitter to put out 700 lumens on its highest setting- astonishing for a light its size. Unfortunately, the single cell internal battery can only keep pace with that output for a little over an hour. Except for on extremely fast descents or when using external power, riders will probably spend most of their rides on the medium (260 lumen, 3 hour) setting.

When compared to less recently-developed Exposure lights, the Diablo focuses a good deal of its output in the center of the beam, creating a well-defined spot as well as a fainter (but still quite usable) halo. This provides the Diablo enough punch for all but the fastest road riding. The beam is axisymmetric- I wouldn't mind a more elliptical (wider but shorter) beam pattern, but it's no worse than the vast majority of lights on the market (and an oddly-shaped beam pattern wouldn't necessarily play well with the company's mounts).

Speaking of the company's mounts: Exposure's handlebar mount is probably the nicest I've seen, forged from aluminum with a very slick, rattle-free quick release. In the case of the Diablo, the company's (included) standard mount is fitted with a clip adapter, into which the light itself simply snaps. The helmet mount consists of a pair of plastic tophats connected by a nylon screw. Because the barbell shape touches the helmet, the beam is clipped, leaving a dark area for the first three feet in front of the bike- it's a bit disconcerting when relying on the Diablo alone, but as doing so hardly provides any depth perception at all (or backup lighting should something go wrong), I never recommend relying on a high-powered helmet light alone. The outer tophat has a socket into which a ball-mounted clip fits. It can be frustrating at first to get the hang of adjusting the light in one direction (say, up or down) without affecting another (side to side). With practice, I'm now able to move the light to where I need it without too much trouble. The nylon screw is used to keep riders from overdoing things and cracking their helmets. I was a bit timid with the screw at first but found that, when not tightened sufficiently, the entire mount tends to rotate rather than the light itself. Some sort of texture, rubber, or shaping on the mounting surfaces would probably help. As it stands, the light didn't stay put until after the mount was tightened enough to make a small indentation in the foam inside of my helmet- nothing that makes me worry about the helmet's function, but still a bit painful on a new $200 lid. I also found that the mount was entirely incompatible with my favorite helmet and was noticeable against my head in another. I know several riders who use the mount with their Joysticks and none have mentioned them being uncomfortable. Still, an alternative helmet mount would be nice for riders who don't have a bunch of helmets lying around.

The light itself is CNC machined, in England, by USE, who certainly know their way around the machine shop. While not heavy, the Diablo is certainly solid. The heat sinking fins are nicely integrated as are a pair of small holes for attaching a tether (handy for riders whose local trees have the potential to grab the light from their helmets). The multi-function switch/battery gage can be a bit hard to locate when wearing thick winter gloves (the nearby Smart Port is roughly the same size and shape) but provides positive feedback when clicked.

While negating the advantages of the company's Cable Free Design, the addition of Exposure's $100 3-cell external battery takes the light's run time over 4 hours at 700 lumen- not bad at all for a $350 helmet or handlebar mounted light- and this is how I've been using the light. One of my other justifications for buying the Diablo is its suitability for commuting. Being helmet mounted, the light doesn't have to be removed from the bike when locked or left outside. Having a very bright "flash" (really more of a pulse) mode that is mounted high and can be directed toward merging traffic helps the rider to stand out, especially around dawn and dusk. The flash mode can apparently run for days between charges- meaning that most riders will only need to recharge over the weekend.

As far as accessories go, the $50 White Eye clip-on LED can add 240 lumen to the Diablo's output, though few will find it necessary (especially as its use precludes that of an extra battery and will take high-power runtime under 1 hour). I had high hopes for the 80 lumen Red Eye Clip tail light, but until its position is better adjustable (it points skyward when the Diablo illuminates the road) and adds a flash function, I'll be holding off. I was able to mount the Red Eye (which was designed for seatpost mounting) to my helmet in a way that was very visible- until my commuting bag was full, when it blocked the light. At $20 more than a decent blinking light, the Red Eye concept could be great with a bit of work. The $50 single-cell piggyback battery can be strapped to the helmet or clipped to the light itself to provide a 2-hour runtime on high. That's great, but for another $50, the three-cell battery (and 4 hour runtime) is just too good to pass up.

My biggest beef so far is that, when equipped with the external battery, the Diablo seems to preferentially drain its internal battery. This keeps the rider from throwing the external battery on the charger while wringing a bit more riding time out of the light itself. While that's no worse than lights without internal batteries, it's something I'd love to see changed. Also, an alternative helmet mount would be nice, for the reasons I mention above. Still, for commuters the Diablo is a great solution. Being able to direct light at specific drivers (say, merging from side streets or turning across traffic) helps to ensure that the rider is seen. The medium output is a bit feeble for spirited mountain biking, and the $200 Joystick will provide that in a lighter, more compact package. Mountain bikers will find that with the 3-cell external battery, the quality construction, light weight, 700 lumen output, and 4+ hour runtime make it a better deal than just about anything on the market. I'm going to keep riding my Diablo through the winter and will be back with a final review this spring.

bikefix Exclusive Review: Hope Mono Mini Pro disc brakes

I have been using Hope brakes off and on for years. Hope set the benchmark for how disc brakes should feel when they introduced the Mono Mini. Unfortunately, those brakes didn’t have quite the power that we in the Rocky Mountain region like to have. More importantly, they also tended to fade quite a bit on long descents, and although this was common with most disc brakes when the Mono Minis first arrived on scene, most manufacturers improved their brakes in this regard, and soon after, serious fade was rare. When the “Pro” version of the Mono Minis was announced, they were just too pretty not to buy. I ordered a set and installed them on my original Maverick ML7 from 2001, which I keep as a fun alternative in my quiver of bikes. The Pros were the same design as the regular Minis but lighter due to Ti bolts, carbon levers, and rotors with aluminum spiders. Hope has since re-named this brake the Mini X2 Pro, but it is essentially the same brake.

I still ride the ML7 a fair amount, but I don’t take it on the epic rides or bring it with me on trips, so my experience can’t tell you if the Hopes have improved on really long descents common in the Rockies. I will tell you from past experience that they can handle this type of riding, but fade is noticeable and other brakes do it all better- except lever feel. Hope still rules the industry on lever feel. The Hopes are totally worth trying if your downhills tend to be shorter. I ride this bike in our “East Mountains” (the Manzanos) all the time and brake fade is never an issue in an area where a single downhill is 1,000–1,500 ft: not bad, but not nearly the 4,000 – 6,000 you can find in our other mountains. The Hopes also modulate with the best of them. Since they are a bit less powerful than some of their competition, this is an easier feat to accomplish, but nevertheless, control of the bike is exemplary. The lack of power that I have been mentioning is only noticeable at one moment- on really steep grades where you have built up any kind of momentum. In that moment, they can give you a scare, because when you pull down harder on the brake lever, not as much happens as you expect. This really sounds worse than it is- it probably isn’t even much of an issue if you only ride the Hope brakes, but coming off other bikes with more powerful brakes makes the feeling more pronounced. That being said, these brakes could work well for many riders out there, with XC racers being one of the most likely groups.

The rotors that come with the Mono Mini Pro brakes are very much worth mentioning. In fact, I considered doing just a mini review (excuse the pun) of them. This is especially relevant since I recently did a review of the Scrub Components' lightweight metal matrix rotors. The Hope Pro rotors weigh only 79 grams in the 160mm size. The Scrubs weigh 60 grams but are very expensive (and leave a bit to be desired in terms of performance). Most regular rotors weigh in around 100-140 grams. This is not a bad way to shed some weight from one of the areas of the bike (the wheels) where weight makes the most difference- without compromising stopping ability. Hope two piece rotors can be purchased separately ($65 in the 160mm size) and look fantastic- racers should weigh their rotors and see if an upgrade might be worth it. One warning: The Hope rotors with the black spider are the X2 version and can be easily ordered by your LBS from many of the big parts distributors- but weigh slightly more at 89 grams. Hope has told me the Pro rotors are available separately but I have never seen them on any distributors’ websites, so they must come directly from US importers Hope Tech USA.

All in all these are good brakes with excellent modulation. I plan to try the company's new Tech X2 brakes this summer and hope to be able to say that those don’t suffer from fade, but these do once they get hot. Still, they are a fine choice for those of you who race, or live in states that are vertically challenged. The Mini Pro X2s retail for $370 per wheel.

bikefix Exclusive Review: Exustar CG510 gloves

Regardless of the home country of brand name they bear, some of the (and some would argue the) best bikes, accessories and apparel are now coming out of Taiwan. While Boulder, Milan and Morgan Hill (and to a lesser extent Waterloo, WI) could be argued to be homes of the cycling industry, virtually nothing that we ride, carry or wear actually comes from these places. Giant and FSA are some of the best-known Taiwanese companies to have made their own name at retail, but a number of other overseas manufacturers are looking to follow in their footsteps. Almost 20 years ago, Exustar began life as VP's high-end pedal arm. Ten years later, the brand broke off from its parent and was reborn as Exustar. Now diversified considerably into shoes, accessories, tools and apparel, the brand (through distributor Q Cycle) is making a push into the US market.

Seeing as they're right down the road, we stopped in on Q Cycle and had a great talk with owner and industry veteran Bill Imielski. He and his team have a lot of experience working with vendors to build and improve products that most of us are familiar with and are excited enough about Exustar's product to ask us to reveiw a couple- the first of which are these gloves. Though they're described by Exustar as "full finger winter gloves," the CG510's are what most riders would consider spring, summer and fall mountain bike gloves. They are no thicker than anything but the thinnest full finger gloves from other brands and are not warm enough for riding in temperatures below 50 degrees. In fact, I find the CG510s comfortable for riding into the low 80s and above- so will be reviewing them as full-finger summer mountain bike gloves.

The CG510's feature single-layer breathable fingers, largely single-layer synthetic palms and a full-terry thumb. The back of the hand is an open, breathable fabric. The protective bits are molded rubber and those over the knuckles are mounted to a cool floating neoprene panel, which allows them to be fairly substantial without being uncomfortable or interfering with dexterity. There is some thin gel padding under the black panels on the palm and a good-sized Velcro closure under the wrist. Though hard to see in the photos, there are the obligatory (but rarely durable) grippy patches on the thumbs and first two fingertips.

Like most 'serious' cyclists, I tend to recoil a bit when I hear that gloves have gel padding. Everyone's tried on (or owned) gloves with thick gel padding that make holding the bars feel more like holding on to slippery fish- they may be comfortable to some people, but have never done much for me in the way of bike feel or control. Exustar have made sure that this is not the case with the CG510s. The gel padding, while identifiably "gel" is extremely thin and provides very good bar feel and bike control, while making them some of the most comfortable gloves I've worn. With no other changes, I find my hands far less tired after long rides wearing the Exustar's than when wearing any other gloves I own. I know that the current fashion is for unpadded gloves, but for riders whose preferences tend toward longer rides, a bit of well-placed padding goes a long way.

My complaints with the CG510's are few and relatively minor. The fit is generally excellent, but the thumb seems cut a bit short- a problem I've never noticed elsewhere (and I wear size Large gloves in almost every brand I've tried). It's not particularly uncomfortable, but is noticeable when the seam works its way under the thumbnail- another 1/8in would be nice in my case. When riding, the floating knuckle guards seem to fall a bit high- more on top of my knuckles than in front of them. Again, it's not by much but should be an easy fix. A bit more protection for the smallest knuckle would be nice, as mine tend to hit trailside branches much more than my larger, inboard knuckles and the floating panel could probably handle more protection without being uncomfortable. Again bucking mountain bike fashion (this time for earth tones or more 80s-influenced colors), the CG510s are only available in red, which will unfortunately rule them out for a lot of riders. Finally, covering a good deal of the (much appreciated) terry thumb with armor is silly and makes it uncomfortable to use. I'd suggest just leaving it off (and removed mine with my handy seam ripper), providing plenty of absorbent fabric for hot or cold rides (right thumb sweat, left thumb snot).

After several months of constant use, the $40 Exustar's are holding up well. I am amazed that the grippy patches on the fingers still look new, as do the back of the gloves. There is a bit of pulling on the terry thumbs and the palms are pilling a bit- but there's nothing to suggest that they won't last for at least a season of hard riding. Striking a great balance between comfort and control, they're very comfortable for even the longest rides. Exustar have clearly put a lot of experience to work here and put together a very good product. With a couple of minor tweaks, they could be as good as, if not better than, anything else I've tried. If the gloves are any indication, Exustar will be a brand to watch.

bikefix Initial Review: GORE BIKE WEAR Oxygen Thermo jersey

For as long as I've owned full-zip cycling jerseys and jackets, I've wondered if there was a way for manufacturers to avoid the belly pouch that zippers inevitably create. It turns out that someone over at GORE may have figured it out- and it's so simple that I'm amazed that no one else had thought of it earlier. While jerseys don't often have much detail to write about, the handful of details that make up GORE's Oxygen Thermo jersey are spot on. As unfamiliar readers might have guessed, GORE BIKE WEAR (their capitalization, not mine) is a branch of WL Gore & Associates- the company that makes GORE-TEX and WINDSTOPPER fabrics. As we're finding out, the details in the German-designed range of cycling clothing and accessories is more than just a vehicle for the company's fabrics.

Charlie and I have both long admired GORE clothing from a distance. While the slick ads in UK magazines no doubt helped, so did the no-frills, unabashedly technical look of the clothes themselves. We sat down with Jessica from the company's US office at Interbike this year and were impressed with what we saw. They offered to send out a handful of pavement and dirt pieces for us to try in the real world- the first of which are a jersey and some tights from their Oxygen series.

Ever since I mentioned a while back that I've never been a fan of long-sleeved jerseys (having traditionally preferred long base layers and short sleeve jerseys instead), the world seems to have been conspiring to prove me wrong. After a month of cool- and cold-weather riding in the Oxygen Thermo, I'm becoming more and more of a convert.

The jersey itself is made from an unnamed fabric that's about as close to the 'jacket' end of the 'jersey' spectrum as I can imagine. The fabric is densely woven on the outside with a slightly softer (though not quite fleecy) inside. Two deep, open back pockets provide secure storage for (light) gloves, snacks and hats, while a center zipped pocket with a long pull keeps phones and keys where they're supposed to be. The hem features some substantial silicone grippers to keep the pockets' contents from shifting the jersey and there's a nice little garage at the top of the locking front zipper to keep it from rubbing under the chin. In a much-appreciated nod to traffic safety, long reflective strips are sewn into the seam from the neck to the wrist (and seem much more permanent than printed-on reflective hits).

GORE's catalog breaks their clothing into three general fits: Comfort, Slim and Tight. The Oxygen Thermo is categorized as "Tight"- and they're not kidding. The medium jersey hugs my 6', 145lb frame like nothing else I've tried. What's cool is that, thanks to a stretchy fabric and cut tailored for the riding position, the Oxygen Thermo is not the least bit restrictive- while riding. With it's extra-long tail, pre-bent elbows and extra-high front, the jersey feels and looks goofy while standing- but looks and feels awesome on the bike. Because the front of the jersey is cut high, the zipper isn't pushed up and out by my thighs- there's no belly pouch to be found here.

Because the Oxygen Thermo is designed for cold weather riding, its cuffs are long and snug to keep drafts out. The neck is cut high and tight in the front, which also keeps the wind away (but requires active zipper use as the day warms). The fabric itself is less wind-resistant than some jerseys I've ridden, but also warmer. This makes the GORE more of a layering piece than a standalone- for days in the high 40s to low 50s, I find that it's great over just a short-sleeved base layer. The addition of a windbreaker will easily see this jersey down into the high 30s (if it's sunny). I find myself wearing the jersey over a synthetic tee and under a mid-weight soft shell jacket on morning commutes in the mid-20s- and being surprisingly comfortable (fingers and cheeks notwithstanding)- I haven't tried another jersey that I can say the same about. While wearing winter gloves, I was initially frustrated by the way in which the zipper pull fits into its little garage. Realizing that this was the point of locking zipper (flip its pull up and the jersey can be pulled open without finding the pull itself), I began tugging at the neck of the jersey to cool off a bit, which works just fine.

What would I change? About the Oxygen Thermo, very little. Because the cuffs are so snug (good when it's cold), they're hard to push up on my (admittedly small) forearms when it gets warm- a more elastic fabric there might be nice if it didn't compromise sealing. The fabric (especially across the chest) could be a bit denser to keep the wind out- but probably not much without adding a lot of bulk. That's really it. The cut is fantastic and as a layering piece, nothing I've tried comes close for seriously cold rides. Of course, as a high-end jersey, the $130 price is getting up there. Still, its performance justifies the cost. As I tend to wear it with a base tee, I've been getting away with wearing mine 2-3 times per week. It's also cheaper than (and works far better than) many wool jerseys I've tried over the past couple of years. Just tell the family accountant that you only need one (though it does come in a very nice bikefix orange if you need a second)... Look for a final verdict in the spring.

bikefix Initial Review: Louis Garneau Montana XT2 shoes

It's a well-worn (even tired) saw: If your feet aren't happy, you won't be happy. Not that feet are the only gatekeepers between riders and cycling nirvana, but anyone who's endured hot spots and numbness on even a short ride can attest that unhappy feet can really take their toll on one's mood. With so much riding on their products (and countless ways in which they can go wrong), shoe designers might well have the hardest job in the industry.

When Louis Garneau sent out their new mid-range ($130) Montana XT2 for us to try, I approached them with caution. I'll be the first to admit that I have hard to fit feet. Over the years, I've tried on countless brands' shoes- and only managed to make peace with one. My low arches (if the term can be applied to a straight line from the big toe to heel) but normal foot width lead to what are called "low volume" feet, which make getting shoes' top straps snug enough difficult- and that's just for starters. I was excited to notice when, pulling the Montanas on for the first time, that the overall length of the ratcheting top strap is adjustable by way of a hidden Velcro strip. Also, the inside of the heel is lined with what Louis Garneau call "one-way stretch Lycra," which looks like a fine metal mesh and feels like extra strong velvet in that it is smooth in one direction (when pulling the shoes on) and grabs in the other direction (when pulling up on the pedals). The toe bumpers, while not large, are sturdy plastic. The shoes' uppers weren't exactly glove soft in the way that high-end road shoes' can be, but the fit seemed good and the shoe not heavy but certainly substantial. Altogether, the Montana XT2's come across as a solid and handsome (though not flashy) mountain shoe. It was time to mount up some cleats and hit the trail.

At least south of the (Canadian) border, we really don't see much Louis Garneau gear. The pieces I have owned (jerseys, shorts and toe covers) have ranged from good to excellent, but it wasn't until we spent some time with Heidi at the company's Interbike booth that I realized the breadth of the line. Even without the bikes that are sold in Canada or their ski or running lines, the company's cycling catalog runs to 140 pages- covering clothing to helmets and shoes to gloves and luggage. Garneau make a lot of gear- and many of their soft goods are sewn in Canada and the US. When we ask companies to show us the gear that they're most proud of, it almost never includes reasonably-priced mid-line pieces. The fact that Garneau is particularly proud of their mid-range suggests that they pay as much attention their as they do at the top end- and my experience so far with the Montana XT2's supports this impression.

When I first clipped in while wearing the Montanas, I thought that I might have mounted the cleats incorrectly. The shoes' soles are noticeably and (at first) oddly canted toward the outside. I believe that Specialized do something similar and Lemond's LeWedge shims can be used to do the same thing. The idea from those companies is that most people's feet don't naturally land flat (either under- or over-pronating). By canting the soles so ever so slightly, the shoes' stiff soles are able to more completely and evenly support the feet (though I couldn't find any claims along these lines from Garneau online or in their catalog). It certainly felt weird for the first few pedal strokes, but the oddness went away within a mile or so. Though I hadn't zeroed in on the problem before, when wearing the Montanas, it feels like I'm able to pedal with my entire foot, rather than putting a good deal of pressure on the outside of the foot. I can't say that everyone will benefit, but the canting was certainly an unexpected bonus and felt great in my case.

Also unexpected (but less pleasant) was that the cutout on the inside of each heel seemed too far back and rubbed my ankle bones. Notice the Swiftwick logo on the socks in the first photo- it sits right over my inside ankle bone. This lead to some uncomfortable rubbing to start, but after a week or two, the shoes broke in and, while I do notice the shoe rubbing there on occasion, it's no longer uncomfortable. Moving the inside heel cutouts forward 1/4in would provide my bony ankles more than enough room to do their thing.

Over the past five weeks, I've managed to log over 60 hours in the Montana XT2's and am extremely impressed. They've seen 4-hour mountain bike rides, 50-mile road rides and, after 15 years, my triumphant return to cyclocross racing. They've shrugged off a rock impact that left one little toe bruised and purple. The nylon soles give up very little stiffness to my personal shoes' carbon soles- and probably save a good deal of money in the process. While I haven't done any proper epics, I have to say that the Garneau's have me rethinking my old standbys. When I switch back to my old shoes, the outsides of my feet are uncomfortable by comparison and it takes several miles to readjust.

The only dark cloud in this sunny picture is the wear that the ratchet strap is showing already. It doesn't seem to be getting any worse and a spare pair are included with the shoes (which is appreciated), but it really is too early for that sort of thing. The top strap's ratchet seems a bit fiddly at first, with pressure needed on two independent levers to release the strap. My best guess is that this is to prevent unintentional strap releases, but they can be a bit hard to release a click or two while riding.

Since first pulling the Montana's on, I haven't chosen my old shoes for any rides over an hour or so- they're just more comfortable. For the first time in 10 years, I'm questioning my shoe brand loyalty. The fact that a $130 shoe has done that is a huge testament to the Montana XT2's fit and construction. So far, they're not showing any wear outside of the ratchet strap. If the ratchet and strap don't deteriorate any further, I think that Louis Garneau have every reason to be very proud of these shoes. We're coming up on 24-hour race season, so these will see a lot of miles between now and my final review next spring. Stay tuned.

bikefix Initial Review: Shimano M810 Saint disc brakes

Not too many components on a mountain bike evoke strong brand loyalties like disc brakes. Probably because being able to stop is nice and the brakes are so important in that regard. That makes a brake review tough. You are either preaching to the choir or trying to convert the already damned- it’s hard to change anyone’s mind that already has an opinion. I myself am guilty of some very negative feelings towards a certain brand- all based on one set of brakes I owned a long time ago. Out of curiosity, I decided to look at the chatter on the internet about the new Saints, and found some mixed and very strong opinions.

I have always liked Shimano brakes and when I decided to “re-tune” my 6.5inch trailbike to make it a bit burlier and more downhill capable, the new Saint brakes seemed like just the ticket. They aren’t as heavy as the first generation of Saint brakes and only come in a bit heavier than many current trail worthy disc brake sets. This is even truer if you eliminate the Saint rotors, which are heavy and not necessary for my intended use- so I ditched them for some standard 6-bolt aftermarket 180 rotors by Gusset.

As I headed out the door of my LBS, my downhill riding friend said “be careful, they are very strong.” I rode around in the parking lot first, and yes, the Saints were very powerful and abrupt in their braking. “This could end with me going over the bars today,” I thought as I rode up the trail. I never did go over the bars, but I did have a number of sphincter tightening moments. The modulation on the new Saints is definitely their weak point. After more rides though, I got better at modulating them and realized that they have barely acceptable modulation once you get used to them- its just a very tiny part of the stoke right before they are just grab. My finger muscles got better at this and perhaps those were breaking in a bit too. It is just hard to transition from trail/xc brakes to the Saints. Now I’m not going to lie- they still need much better modulation for them to really become a great brake, but I found on long downhills with high speed involved- they worked perfectly. It’s only at slower speeds that they feel so on or off. This is particularly troubling in terrain that is dry and loose- I definitely had my scariest day riding the Saints on dry, dusty, granular, pink granite. But the more grip you have the more their modulation feels adequate. This is not an excuse, but they are downhill brakes after all. In fairness to the reader I noticed from other reviews on the Saints that modulation issues are very hit or miss with these brakes- so perhaps there is a way to fix it. This is something we will have to investigate.

I played around with the convenient tool-free lever adjustment and the bite point adjustment until they felt right, and I don’t think I have changed them since. The bite point adjustment actually does make the brake feel different as you turn the screw, but I just set it to where it felt “right” having no previous experience or opinion on where exactly I prefer the bite-point. One small annoyance is that the Saint has a one-piece clamp so your grips have to come off when you install them.

The Saints are some loud brakes. They weren’t that bad for a few rides and then it just started to happen- the dreaded squeal. In the end, if anything makes me give up on these brakes it will be the noise. I don’t go on epic backwoods adventures just to stink-up the forest with noise pollution. We've just changed the stock sintered (metallic) pads to organic pads from Kool Stop though. This might help with the noise and perhaps with the modulation too. With winter setting in though, the brakes won’t see any epic descents till next summer- we'll keep you updated. I want to mention that we haven’t spent a lot of our top mechanic’s time trying to correct the squeal (or the modulation for that matter) so this is something else that we will have to try if the new pads don’t help. One wheel's worth of Saint lever and caliper retail for around $270, sans rotor.

bikefix Initial Review: Exposure Lights Strada lightset

This time of year, commuting by bike can be a bit of a challenge. Not only is it colder and often wetter than other seasons, but the end of Daylight Savings Time means that all but the luckiest riders will ride at least half of their commute in the dark. As we mentioned in our overview, Exposure are big into not being into cables. A regular commuter who locks a bike outside and switches lights between bikes, the appeal of a simple, self-contained unit was immediately clear to me. The idea of a road-specific light was a new one, though.

Exposure bill the 480 lumen, $280 Strada as the "the first high output LED cable free light designed with an eye on the road." That's an awfully fine niche, but as the Strada is the first road-oriented light that I've noticed with enough power to both see and be seen, I've got no reason to doubt the claim. What, then, makes the Strada road-specific? The light's two Seoul P4 LED emitters are fitted with lenses that give the light an interesting beam pattern. One emitter creates a nice, distinct spot to allow its half of the output to travel a good distance while the second is fitted with a horizontally-oriented decollimator, creating a wide (though not tall) flood, ensuring a decent lateral flood and good visibility to cars but without wasting valuable output on the front tire or signaling overhead aircraft.

The Strada comes shipped with the same (very nicely) forged quick-release mount as the rest of Exposure's handlebar line and a (wired) switch that cycles the light through high, medium and flash modes. The internal lithium-ion batteries are good for an impressive 3 hours' run time on high, 10 on low and, apparently, "days" when flashing- this means that all but the hardiest commuter should be able to go an entire work week between charges. The Strada also shares Exposure's Smart Port Technology with the rest of the range. This allows for a number of accessories- most interesting for commuters will probably be the seatpost-mounted 80 lumen(!) RedEye rear light, but additional external batteries can be added to increase the Strada's runtime by 50 or 150%. The whole light is built in the UK by people who clearly know their way around CNC machines and (coming from someone who makes things has things made for a living) appears very well made.

Seeing as I couldn't see any reason not to, I mounted the Strada below the bars, parallel to my stem. The narrow bracket, unobtrusive placement and ~200g weight (without the remote switch) meant that the light didn't interfere with normal bar-top hand positions or otherwise make a nuisance of itself. Mounted under the bar, it took a bit of care when attaching the light to its bracket to ensure that it didn't foul my rear brake cable- though that was only an issue once. The Strada was also the first high-powered unit that I've tried that didn't interfere with my analog wireless bike computer.

On the road, the wide (but not tall) beam pattern seemed perfectly natural- because the light was where I needed it, it worked nearly as well as some 700 lumen lightsets I've ridden. Even off road, the Strada performed very well- it doesn't flood the trail, but again- the light is focused where it's most useful. When combined with the company's Joystick helmet-mounted light, it provided more than enough light for spirited mountain biking. In fact, combining the Strada (on high) with a flashing Joystick on my helmet made for some very confident commuting. The Strada provides enough light with which to ride confidently and the pulsing Joystick is very effective at capturing the attention of oncoming left-turners and drivers merging from side roads.

While the $50 Red Eye accessory is appealing for it's powerful output, the non-angled seatpost bracket means that a good deal of that output is used to illuminate the road. Exposure feel that this provides a unique pool of light behind the rider, but by the time a driver at 50+mph notices a reddish pool of black pavement 15' behind me, I can't help but think that they're a bit closer than I'd like. Add in the fact that the tail light does not flash (likely due more to British traffic laws' prohibition of the use of flashing lights on anything but emergency vehicles than anything else), and you've got Exposure's greatest opportunity for improvement. If the bracket were adapted to accommodate standard seatpost angles and a the light to flash, a Red-Eye upgrade would be a no-brainer.

While not inexpensive, the Strada is a very well thought out, well made light. Given its apparent solidity, first-world manufacture and the cost of competing products, the price is very reasonable. In fact, though it this light is most at home on the road, I have to wonder why off road lights don't have similar beam patterns. Commuters should certainly give the Seca a look. As good as the Seca is, for another $70, the company's TORO lightset puts out 700 lumens (in a more traditional, axisymmetric beam) for 3 hours/charge or a comparable 480 lumens for 10 hours. Sure, it's another 25% on an already pricey product, but when it comes to seeing and being seen, that $70 may be money well spent. Depending on how elastic your budget is, the TORO could be awfully tempting- otherwise the Strada will serve serious commuters very well (look for a review of the Toro in a week or two).

bikefix Exclusive Review: Deluxe Seam Ripper by Dritz

Sometimes a tool is perfect in its simplicity and specificity. This is just such a tool If you ride and are at all particular about how your clothing fits or gear works, you've probably come across a pad that has become uncomfortable before its time or pack with unnecessary straps that do nothing but make a nuisance of themselves. Dritz's Deluxe Seam Ripper is a badass little tool that helps the user remove sewn seams without destroying nearby fabric. Its form is perfectly evolved to do that an nothing else- and is beautiful for that.

Over the past month, I have used my Seam Ripper to remove annoying tags, free oddly tethered shoe tongues, remove annoying glove "armor" and bring knackered knickers back to life. All without accidentally slicing though expensive gear with an X-Acto blade or futzing around with scissors. The Seam Ripper is both simple and ingenious. In the crotch of the blade is a very sharp cutting area. The long pointy bit is for getting under stitches. When slid underneath a stitch, the blade is able to cut the thread without endangering the surrounding fabric. Cooler still is the red tip- once a seam is opened up a bit, this side can be slid into and run around a seam, popping each stitch without hanging up.

When I realized that the pad in my favorite knickers had about had it, I was able to use the Seam Ripper to remove it altogether, without disturbing the (very expensive) Windstopper material underneath. Now, I have knickers that can be worn several rides in a row with different shorts on each ride, keeping them out of the wash and my knees happy. Similarly, when my nose started running, I realized that putting "armor" on a pair of gloves' terry thumbs made them pretty ineffective at removing snot. 3 minutes with the Seam Ripper and they're much, much more pleasant to use. The seam ripper can be used to quickly cut poorly-located or overly large tags out of clothing too. Any time, really, when you want to remove a seam without screwing up an expensive piece of gear, they're ideal.

How much for this wonderful bit of tool design? Somewhere between $3 and $5. Even if you don't have a use for it right away, pick one up- it'll come in handy at some point. Nobody will even notice you in the quilting aisle.

bikefix Second Look: Continental Mountain King 26x2.4in UST tire

Aside from being one of the friendliest, most enthusiastic riders we know, Juan Pablo is also an accomplished off-road triathlete, one with the sort of bike handling skills few tri folks posses. Here's his review of Continental's 2.4in Mountain King UST Tire:

I have used this tire on my front wheel (26) off and on for over 18 months. Its latest assignment was on my front wheel at this year's Xterra World Championships in Maui.


My first experience with the Mountain King was in Moab. From Slick Rock to Amasa back, the tire impressed with its grip in slick rock. I was expecting the tall knobs to flex and wobble, but that was hardly the case. The tire was planted and predictable. On the loose and sandy terrain it offered the grip that I was expecting and more. The tire felt light when taking into account its size and when compared to UST tires of similar girth [the Mountain King is nominally a 2.4 but bikefix have measured it at right around 2.2in wide]. It did seem narrower than I expected but the tire has appeared to ‘grow’ a bit over time.

This trip to Moab included some particularly aggressive riding companions that in turn encouraged some very aggressive pursuits. However the tire showed no damage to other than normal wear on the knobs. Surprisingly no knobs where torn or missing- this has been a common occurrence in my experience with tall-knobbed tires, perhaps avoided in part by the knobs’ pyramid-like construction.

I also used the tire repeatedly in New Mexico and experienced Velcro-like performance on loose-over-hardpack and sandy terrain. I consider myself a ‘carver’ and enjoy carrying speed on tight turns, this tire up front makes me question how much more speed can I actually carry though the turn.

In Telluride I rode in loamy conditions with excellent traction; however I reduced pressure to make sure that the Mountain King would clean itself of packed mud. I could see how a big tire like this could cause problems in stickier clay though. I have yet to test it in the infamous Hawaiian clay, but will do soon enough as rainfall will increase in the fall and winter months here on Maui.

My next experience with the tire came as I was preparing for the 2009 Xterra World Championships. In the past (2005) the course has left me with un-pluggable flats on UST tires, and this is the same for everyone, from [three time Xterra world champion] Conrad Stoltz down. The a’a (Hawaiian name for this a particular type of lava) is unpredictably sharp and it litters the south part of the MTB course (due to recent lava flows – 400 years old or so), the place where most of the course’s descending takes place. All of the race's climbing takes place on the North side of the course with a little more dirt than rocks.

In preparation for Worlds, I tested several tires. Basically I rode on a’a with the intention of puncturing a tire. Both my training partner and I punctured other tires rather quickly, or tore knobs right down to the casing. However we were unsuccessful when it came to the Mountain King- it held air. At 170lbs (vs my partner’s 146 lbs), I had a better chance at tearing a tire. After several rides, no knobs were torn or were there any signs of cuts in the casing. I inspected the tire thoroughly. The same was true for the Race King 2.2. UST tire that I ran on my rear wheel: no visible damage. This was amazing considering that I sliced the right-front tire of my SUV on a piece of a’a lying on the side of the county road that is above the MTB course. It is also worth noting that the seal remained tight and no burping occurred, I ran 32 PSI in the front (MK 2.4 UST) and 35 psi in the rear (RK 2..2 UST).

On traction, as I had noted in my previous experience in Moab and New Mexico, the Continentals excelled in this type of dusty rocky terrain. The tire offered a cushy ride- I did not measure it rolling efficiency but it does feel a tad slower than say a Racing Ralph or it sibling the Race King, but that is to be expected.
