I like the look of the CycleOps Fluid 2 which seems to get good reviews and costs about £200. I'm looking to get one to facilitate a gentle re-introduction to cycling following surgery to implant a pacemaker. To be honest, going straight back out on the roads this time of year is a bit daunting as I don't fancy the prospect of falling off. Stupid I know when I've been cycling for 6 years+ with no significant accidents, but such is the human mind. Anyway, 2 questions of my own if I may. Firstly, how do most people track their turbo trainer workouts? Is it just time? or people also track equivalent distance? Secondly, are there risks that a turbo trainer might in some way damage the bike frame?
