bikefix Exclusive Review: Topeak PrepStand Pro repair stand

While most of us probably started working on our bikes upside-down in the garage, leaning against a workbench or hanging by the saddle from a hook in the basement ceiling, there comes a point when a proper bicycloe repair stand is very helpful. There is a wide range of models available, from inexpensive collapsable models through stable portables to professional models that weigh close to 100 pounds. While the best-known models come from Park and Ultimate, there are a number of unique and viable models available from other companies- including Topeak.

My positive experience with Topeak's Dual Touch bike storage played a large part in my decision to try the company's PrepStand Pro. The two model PrepStand line feature a collapsing tripod base, much like the portable speaker one sees at concerts and no doubt informed by Ultimate's successful use of a similar design. Solid composite joints and aluminum quick-release levers connect the aluminum tripod base to a 2-part telescoping 6061 aluminum trunk. The jucntion that supports the clamp arm is meaty aluminum, as is the arm itself. What sets the $280 PrepStand Pro apart from the less expensive ($215) PrepStand Elite (and from other repair stands on the market) is the digital scale integrated into the arm. At the end of the arm is a fairly simple clamp that can be closed around a wide variety of tube shapes by turning a small-ish knob. It all packs into an included 46x7x7 padded carry case, which is convenient for those without a dedicated workshop or for traveling to friends' or races.

While very stable when set up, the long legs that give the 12lb PrepStand its solidity can be a bit of a hassle. The 120 degree spacing of the legs mean that, when two are aganist a wall, the third tends to get underfoot. My biggest complaint, however, comes from the clamp. The clamping threads seem to have an intermediate thread that is neither quick to close nor provides as much clamping force as a 30lb mountain bike really calls for. A larger knob and/or some sort of free spinning "suicide knob" would no doubt help (though it may compromise portability). Also, while the clamp can be rotated 360 degrees, the serrated faces that prevent the clamp from moving once in place make adjusting a bike's angle difficult- the adjustment knob must be backed out quite a bit and the bike's weight supported while being repositioned. Compared to friction adjustments on competing stands, this can be a bit of a hassle. Collapsing the PrepStand, on the other hand, is a breeze, and it takes well under a minute to collapse the stand and place it in the carry bag, which is nicely made and fits very well.

The scale, which is located on the clamping arm, is handy, although with a 20g resoulution, it seems better suited to satisfying curiosity than anything else. I can't speak to its accuracy, but do use it from time to time (which QRs are lighter?), and complete bikes can be easily weighed by hanginf them from the nose of the saddle.

It's been a few years since I purchased my PrepStand Pro. In that time, it has proven both reliable and sturdy. Because its ease of use isn't quite that of competing stands, I probably wouldn't seek it out. The materials used and most of the design are top-notch, though, and with a revised clamp and rotation mechanisms, though, it would be one of the nicest and most compact repair stands I've seen.

bikefix Exclusive Review: Saris CycleOn Pro bike rack

I haven’t owned a bike rack since about 1992 and it was such a piece of crap that I haven't owned another since. Times have changed and my need for more bike-carrying capacity has grown. I talked to a number of friends about their recommendations and Saris' CycleOn Pro came out the winner. I ordered the rack, and had a 2in receiver hitch installed on my truck.

When the rack arrives it requires some assembly. I hate any kind of assembly, but it wasn’t too bad and I had it done and installed on the truck in less than 30 minutes. The rack is sold with a locking hitch-pin (to lock it to the vehicle) and a cable style lock for the bikes (to lock them to the rack and/or vehicle). While the base CycleOn and CycleOn Pro will hold two bikes, I had ordered the additional 2 bike add-on so I could now fit a total of 4 bikes behind the truck. Crap. I forgot about the spare tire. I was down to 3 bikes and now the rack didn’t fold up and out of the way when not in use as it's supposed to. A quick search around town talking to the “experts” lead me to believe that there was no way to extend the receiver out; or that the shortest extender I could buy was 18 inches long- far longer than the 5 or 6 inches I needed. After being generally annoyed for a bit, a friend recommended an Internet search. 1.38674 seconds later I found a 7 inch receiver extension and ordered it about 2 minutes after that. I believe in supporting your local shops but our local U-Haul and trailer shops had no clue. Sometimes the Internet is the better way.

The Saris allows one to put the entire bike on the rack without taking either tire off. A simple but strong arm swings up and ratchets down on the front tire. Saris claims that it touches no part of the bike other than the tire so there is no rubbing or scuffing between rack and bike, or between bike and bike. Overall it works as advertised, but (and it is a BIG butt), the rack does not like SRAM derailleurs. This is upsetting to me because I like SRAM XO derailleurs and most of my bikes and my friends’ bikes have them. The arm that holds the bikes in place protrudes into the space that the XO derailleur would like to have. So you either turn the bike backwards in the rack (which is probably not recommended and creating new problems) or you tilt the bike a bit to get the arm lock into place, and then let the pressure of the locking arm push the derailleur against the previous bike’s locking arm- so much for no scuffing (not to mention the possibility of breaking a rear mech). Even more frustrating is the fact that it's such a simple fix. The lock arms are unnecessarily thick where the plastic lock mechanisms are and the SRAM XO only needs about 4-6 mm of extra room- Hell, I may well just Dremmel away at the plastic until it fits.

Since I am on a rant, I might as well mention that the bike trays that the tires fit in are perfectly parallel. This means that the handlebars of every other bike are in exactly the same spot. Why couldn’t they make the add-on trays slightly angled in the opposite direction- then the bars would be staggered slightly. Sometimes saddles get in the way of the bike next to them but that was expected and is easily fixed too by removing the seat post or rotating it 180 degrees in the seat tube).

The Saris is well-built however, and will work for a lot of bikes, but the add-on creates some issues and the SRAM thing is annoying in the extreme. The moral of this story and my advice to you is: try before you buy. Of course, you now know whether this rack will work for you. The CycleOn is available for either 1 ¼ inch or 2 inch receivers. It retails for around $440 for the base rack and another $270 for the add-on.

Now, I was one of the ones who recommended the CycleOn Pro to Charlie and feel like I should weigh in. After seeing how poorly my existing roof racks fit my new Saabaru and buying a home with a garage, I decided that it was time to rethink pushing multiple bikes through the air at 80mph for hours on end. After looking around, I decided to go with the Saris for its well thought-out design, American construction and lifetime guarantee. Unlike similar offerings from Thule, the Saris' locking arm doesn't contact the front of the bikes' forks- it locks at a preset angle. Because I'm not a SRAM guy, I haven't had problems with deraileurs rubbing, but bars often conflict with nearby saddles. After hearing about Charlie's problems, I did some experimenting. Whether or not your rear dérailleur hits the arm or not seems to have more to do with the bike's wheelbase than anything else. Charlie and my Mavericks have long-ish wheelbases and my XTR mech has the same problem in the outer position. Other (shorter or longer wheelbase) bikes, including 29ers and road bikes are fine. As Charlie says, try before your buy. Bar conflicts can be addressed to some extent by winding down adjustable-travel forks.

In use over the past three years, the CycleOn Pro has been generally good. The Pro model, over the base $380 CycleOn, adds a locking cable and expanding tongue. The cable is nice enough and keyed to match the hitch pin lock, which is handy. While the expanding tongue (the square tube that goes into the receiver) is nice, it won't keep the rack from bouncing around without a stout receiver. The 1 1/4in receiver that U-Haul sells for Subaru Imprezas isn't particularly stout. On another, with a better receiver, there is almost no rack movement, even without the using expanding tongue. If you have a fairly solid receiver hitch (like those that come on many SUVs) and aren't planning on carrying more than two bikes, I'd recommend saving the $50. If you have a suspect aftermarket receiver, you'll need all the help you can get.

Because the rack is removed so easily, I tend to leave it in the garage when not in use. When on the car but not in use, it does fold upright very easily, though this can restrict trunk/hatch access. After opening my trunk into the arms a couple of times, I stretched old tubes over them to keep prevent scratches. On the road, you can keep an eye on your babies. The roof rack wind noise that can render sunroofs useless is gone and fuel economy is much improved. The likelihood of hosing your bike/rack/roof by plowing into a garage or basketball hoop is greatly reduced as well. Obstructing your license plate with bicycles will attract the unwanted attention of Utah's Finest, but if you're nice and not drunk or high they may let you off with a verbal warning.

On cars with low exit angles (lots of rear overhang), the rack will hit the pavement (or dirt) from time to time. My knob for the expanding tongue is broken and the bottom of the rack pretty chewed up but still performing admirably. The rear wheel holders aren't designed to accommodate deep section aero rims, but 29ers fit fine. Overall, I have to say that the CycleOn is one of the better thought out and built racks that I've seen. Not cheap, but start adding up the cost of roof rack components and you'll get there pretty quickly. For $270, the Saris Thelma looks awesome but isn't 29er friendly.

bikefix Exclusive Review: Pedros Hex Pedal Drivers

More tools. I really like a well thought-out, well made tool that meets a specific need. Over the past few years, many pedal designers have, in the interest of simplicity and weight savings, done away with the 15mm wrench flats for attachment (to the crank) in favor of 6- or 8mm hex sockets in the end of the spindle. This is a good thing, because far more people carry hex wrenches on rides than 15mm open-end wrenches. However, as anyone who’s tried to remove a stuck pedal knows, sometimes you need a really big wrench to get them unstuck. From experience, I can tell you that it's a Very Bad Idea to use a cheater bar on a generic Harbor Freight hex key. Pedros have apparently heard the cries and seen the skinned knuckles and come out with some really stout pedal-specific hex wrenches.

These things are cool. They’re about 8in long, and look like the bastard offspring of a ball-end Allen key and Craftsman screwdriver. The ball end is good for getting the pedals on quickly, and the screwdriver handle provides plenty of surface for cranking on. That’s it. They’re big, badass hex wrenches. Good for tightening single speed hubs and Soulcraft chain tensioners, too, but try to go easy on other parts of the bike. Available in 6- and 8mm sizes from Pedros for between $12 and $15 with a lifetime warranty, and the handles are now black.

bikefix Exclusive Review: Park AWS-1 & AWS-3 hex wrenches

With spring just around the corner (or so I hope) and more daylight available after work, I find myself drawn to my garage workshop more and more frequently. It's not necessarily that anything really needs doing, but it feels good to be out there, tidying and fettling after dinner. Figuring that I'm not alone in this, we'll be looking at some essential tools over the coming weeks and months.

While changing out some handlebars lately, I realized just how nearly perfect the Park AWS-1 wrench really is. Modern road and mountian bikes feature a whole host of of fasteners. While high-strength Torx fasteners are becoming increasingly common, the vast majority of fasteners on most bikes are of the 4-, 5-, and 6mm hex variety. In fact, I can probably count on my fingers the number of fasteners that aren't one of the three. Park, most mechanics' favorite tool company, realized this and (about 20 years ago) came out with their AWS-1.

It's a simple tool, really (see the picture), but very well executed. Three 2in hex keys point out of a squished plastic puck that fits very well in the hand. The keys (available in stronger straight and versatile ball-end versions) are made out of very high-strength (Bondus Protanium) alloy steel that is very resistant to rounding. As many of us have learned from experience, using a rounded tool is one of the best ways to hose a perfectly good fastener. There is enough length in each key that, should you manage to hose one, you can use your bench grinder or Dremel cutoff wheel to shave 1/4in off and carry on. The arms are long enough to provide enough torque for most any bicycle application, and having all three common sizes in hand is great for common tasks (ie: stem and bar swaps, gear adjustments and so on).

The AWS-3 in the title and pictured above is the little brother of the AWS-1, and has 2-, 2.5-, and 3mm keys (as used on Formula disc brake levers and Rock Shox "we'll use every fastener size we can find" remote lockout assemblies). While there are several similar tools available (from Pedros and others), none that I've seen have been as durable. Do it right and you'll only have to do it once (besides, they're under $10). Since mine were made and purchased (I keep one on the workbench, one in the car), Park have revised the AWS-1 for more strength and better ergonomics. While I don't see mine wearing out, these do have a funny habit of going missing. When this happens, it'll be replaced quickly with the same thing.

bikefix Exclusive Review: Topeak Dual Touch bike storage

Bikes are great. But they sure a pain to store. One isn't too bad, two can be manageable, but if your household includes 4 or more bikes, they can really start to take over. There are a number of bicycle storage options out there, but none have ever seemed perfect. While the $2 nylon-coated hook can do quite a good job, those require drilling into walls or ceilings (preferably then into studs) and you're usually stuck with bikes coming straight out of the wall. Wheel stands are versatile, but they leaves loads of space above the bike(s). There are a number of leaning storage racks out there, but most aren't particularly flexible. Just leaning a bunch of bikes bikes somewhere is just asking for a messy pile of scratched bike.

Topeak, who make a surprisingly wide range of (usually) well thought-out cycling accessories, have been selling the Dual Touch bike storage stand for several years now. A renter at the time, what drew me to the Dual Touch at the time of purchase were its adaptability to different ceiling heights and non-permanent (no drilling required) mounting. A pair of telescoping tubes extend to press non-marking white suction cup feet against the ceiling and the floor. A foot-operated cam provides a bit of oomph and locks the whole thing in place. That's it. A pair of cradles hold bikes' top tubes. The spacing of the cradles' hooks can be adjusted, as can their angle, so can almost always be set up so that the front wheel doesn't flop around. The cradles can be easily slid up, down and around the tubes and are locked in place with a large knob on the far side (see pictures).

All of the Dual Touch's hardware has proven to be quite well thought out and is built of aluminum or the type of composite typically seen on car roof racks. The hardware is metric and most can be adjusted with a common (for cyclists) 5mm hex wrench. In about 5 years of ownership, the only problem that I have had is the occasional slipping of the quick release that holds the setting of the telescoping tube- though only while setting up the stand and not in use. From time to time, 1/4 turn of the QR's allen bolt helps to put my mind at ease. I also snapped one of the cradle hook bolts once, but a replacement was easy to find. While not cheap at $135, the design, construction and materials are far better than other bike holders I've seen and seems reasonable for something so durable. Thanks to the lighweight materials, each rack only weighs 11lb and easy to set up, store or move. Mine have adapted to a number of apartments and houses without complaint. Additional bike hangers (for freestanding installations holding up to 4 bikes) are available for around $30, but I would probably keep it to lightweight road bikes at that point.
