- seren 12y ago> The tests showed that shaving his legs reduced Thomas’s drag by about 7 per cent, allowing him to exert 15 watts less power and still go at the same speed. In theory, that translates to a 79-second advantage over a 40-kilometre time trial that takes about one hour. Shaving reduces the drag, but the originally study measured the reduction around 0.6 percent while this one found a 7 percent reduction. So, about 10 times bigger than anticipated.
