It’s hard to argue with maths so the guys over at BikeRadar got Dr. Howard Hurst to test all three wheel sizes with multiple riders over the same course and record every little bit of data to see which wheel size is actually the fastest. The winner may not be a real surprise but the 2nd place wheel size was quite unexpected. And the fasted wheelsize on the descents will certainly surprise you. So that is that. Are you surprised by the results?
