I know that Kurt Kinetic, Tacx, and Cyclops work with 15mm bolts. And, as Scrod said, if your axle pokes out past your 15mm axle nut, you'll have to put on another axle nut to cover the excess before you mount the wheel into the trainer. I've had to do this before.
For a rather handy person do you think it would be all to hard to build your own rollers?
Making the frame might be do-able. But making the drums would probably be difficult.
It may not be worth the trouble being that Travel Trac rollers are only $150: http://www.performancebike.com/bikes..._1028745_-1___
Oh and another question, when you go from your track bike bars (no hoods) to road bike (has hoods) do you have a different reach? I recently got some hoods but to use them I now feel to stretched out...
I have a 2001 Jamis Quest road bike with 105 that I bought from someone through craigslist, for $500. It has an Easton ec70 carbon fork, that fork has a carbon steerer tube. Here is my dilemma which will lead to my question. I do road long road rides on that bike, where a carbon steerer tube might give some kind of advantage and also next season I want to start racing. BUT, some days I commute on that bike or just ride it around for fun, basically not competitively or for training. I feel kind of insecure with a carbon steerer tube just because I don't baby the bike and I don't want to destroy/damage the fork and/or grind my face on the ground. SO, here is my question. Should I try to sell that easton fork and just get another fork that is carbon, but has an alum steerer tube, or should I just keep riding that fork and not worry about it because carbon is strong enough to handle some abuse? And if you recommend selling it, assuming it is in good condition, what should I ask?
Stage races are races that take place over several days or weeks like the Tour de France. The TDF is 20 days with only 2 rest days. It is a war of attrition, meaning the guy who stays stronger longer will do better. For example:Blood doping is the practice of boosting the number of red blood cells (RBCs) in the bloodstream in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete’s aerobic capacity (VO2 max) and endurance.
As far as what track racers do, I only know of 4-5 track racers over the past 20+ years that were busted for any kind of doping. That is a ridiculously small percentage compared to the numbers of people who were tested over that time period.Tour de France rider Alexander Vinokourov, of the Astana Team, tested positive for two different blood cell populations and thus for homologous transfusion, according to various news reports on July 24, 2007. Vinokourov was tested after his victory in the 13th stage time trial of the Tour on July 21, 2007. A doping test is not considered to be positive until a second sample is tested to confirm the first. Vinokourov's B sample has now tested positive, and he faces a possible suspension of 2 years and a fine equal to one year's salary. He also tested positive after stage 15.
The percentage of HS football athletes taking performance enhancing drugs is higher:
So to answer your question, I don't know. But, I would imagine that the percentage is much much lower. Also, there is no money in track cycling. Especially in the US. Even the pros don't make big bucks.Results from the 2006 Monitoring the Future Study, which surveyed students in eighth, 10th, and 12th grades nationally, show that 1.6 percent of eighth-graders, 1.8 percent of 10th-graders, and 2.7 percent of 12th-graders reported using steroids at least once.
When there is a lot of money on the line, people will do lots of things.
Doping is an issue in ANY sport that pays well: Baseball, Football, Soccer (in any country but the US), etc... For some of these athletes, they don't have anything to lose. When they get older and their skills and strength start to wane, it's either dope with some chance (%) of getting caught and losing money or get cut from the team due to lack of performance with 100% chance of losing money.

I guess a good first question is, how fragile are carbon steerer tubes?
Also due to the fact that alu and carbon don't bond perfectly, a fork with a carbon steer tube can theoretically be made stronger and lighter than one with an alu steer tube. This is because the full carbon fork can use longer strands of carbon. Generally speaking carbon fork fail for one of three reasons, all of which are easily preventable. Either clamping the stem with too much torque, using an incompatible stem not designed for a carbon steer tube, or much more rarely not leaving a spacer above the stem. These issues usually arise through user error. I'm pretty wary of used carbon fiber for this reason. So in the end, the question becomes, how much do you trust the mechanical ability of the person that you bought the bike from?
Carleton, I know this is an old image, but can you explain how this sort of thing can happen?
Tryna sprint to the finish.
It's a really quick flick up and down that just so happens to get caught by the camera at the right time.Thanks to his classy sprint style where he regularly pulls ‘Wheelies’ as he crosses the line, Awang quickly became a crowd favourite, and the atmosphere in Poland could easily have been mistaken for a home crowd for the rider from Malasyia
“This wheelie thing is now my trademark, something people remember me for, you know just like Michael Jackson with his style or Elvis Presley with his thing. As well as winning I want to make my race look exciting so that people enjoy watching it”
