I signed up for Cohutta 100 and I decided to check the single speed box. I have a powertap on my 26 inch geared bike and was thinking of switching out all my bikes to 29ers, so eventually I'm going to lace my powertap to a 29er hoop. So now I'm getting the idea to run the PT on the SS. Anyone ever do this before. Do you find the PT numbers useful at all?
