People who ride 53x12 have no ****ing idea what they are doing. 'cept the ones called Jan Ullrich
He reaches 100rpm (well, he would, but never does, obviously) at 77km/h (48mph). What's the point of riding fixed if you never even get up to 80rpm??? Where's the smooth spin, or the agility, the control of your speed through your legs? [/rant]
