This is an age old debate. For the record – I’m not a proponent of shaved legs. However, a recent set of wind tunnel tests showed that one could save up to 70 seconds in a 40 km time trial by shaving the legs. That is like 5 minutes on an Ironman distance race which is a lot of time for … nothing. Will I shave? No. But if you are serious about your cycle times its one thing to consider. Here is a video of the wind tunnel testers describing their surprising findings.
