I traded my i-magic virtual trainer for them. I liked the i-magic but honestly I wasn't using the virtual function to train with so essentially it was just another mag trainer. Rollers are neat cause you have to actually do something other than pedal, and I can really see how they are going to help me with my bike handling. Getting to the point where I can stand and sprint is going to be fun.

Question, how do you guys mount with out a step stool or something to lean on? I ask this because I'd like to take these to races to warm up on.
