I'm not sure of the price. There are many out there to choose from. I have had my McLain rollers for
12 years I know of. They still roll great. They help you focus on smooth pedaling and accelleration.
If you have noticed, when some riders pedal on straights and are trying to accelerate the rear of
their bike seems to sway abnormally...That is from not having control. You can get control of that
abnormal sway by using rollers. Some people don't think they are worth the trouble and deplore
rollers over the fixed fork ones. I find that on a fixed fork trainer I am uncomfortable with the
riding position.I feel like I am leaning whenever the trainer is set up correctly. Apparently, I
don't ride my bike exactly straight up and down. Another plus for having a roller trainer is that
you can focus on high cadence intervals.
A better idea for training would be to have both a fixed fork type of training system and Rollers
for training.
Remember, if the learning curve on the rollers doesn't kill or maim you for life then you will
become a better rider.
imho,
