I'm about to get a new CycleOpts Fluid2 trainer for use this winter but need to go out and buy the front stacker/balancing block to use with it. I split my riding time equally between my road (Felt F80) and MTB (Specialized Rockhopper) and am trying to figure out which one I will put on this trainer. I was leaning towards my MTB as I'm the most comfortable on it. But, I'm trying to train for a charity ride next summer where you do back to back 100 mile days. I could mix and match and buy different stackers for the front tire, but that would probably be more of a pain in the butt then it was worth.
So which type of bike do you think would give me the best workout? What do you prefer on your trainer?
