Which would be more beneficial/cost effective...use my PowerTap Pro (wired) on a cheap road bike or are there second hand Disc PowerTaps out there? I do train on the road a couple of times a week, but rest is off road. How important is it to get power stats from a mountain bike race? I would probably only use the heavier PT wheel on less important races.
Any ideas, advice?
