clamp,
weren't you the one who told me you significantly decreased your drag coefficient by shaving your back?
No --I comb it to a point like a down hill skiing racer and put vaseline on my eyebrows. Hey every little helps.
If your into small fractional minuscule performance enhancement improvements, taping your ears back I find helps up wind, and only set tyre pressure on a dry day or your tyre air will be damp and weigh more.
Im sure some other members would like to share are thier performance tips?
