I train on rollers all the time in the winter, but I usually just use my road bike. I want to start using my tri-bike, but I don't have a death wish (no desire to even attempt to get down on the aerobars while spinning on the rollers). I know Kreitler sells a fork mount you can set up over your rollers. I've checked them out online and the thing I can't figure is if they're height adjustable. My tri bike has 650c wheels. Don't want to buy the forkstand if it's only designed for 700c wheels.

Anyone have one of these and know if it's height-adjustable?

Thanks,

Bob C.
