I have a bike on a Cyclops fluid trainer and it works great, parked in front of a flat screen TV in the workout room. But now my wife wants a spin bike in the worst way and my bike is way too big for her to ride. She tried a RevMaster at a hotel health club spin class while we were travelling and loved it, so is now pushing for that. I just don't have space for both. The question is this: can I use the spin bike for Sufferfest videos and other race related workout DVD's that feature interval/climbing? The reason I ask is that I shift gears on my bike to increase effort and keep cadence steady and I'm not sure how/if this works with a RevMaster. Do I need to stop and screw that damn knob every time I want to increase/decrease resistance?? Thanks in advance.
