Ridden to a 2013 World Championships win by Caroline Buchanan, a silver medal by Marc Willers and bronze by Manon Valentino, Box One M35 Cranks have proven themselves as the go-to choice for elite BMX racers.

What makes these Box BMX cranks so special is that they are the world's first with a Praxis 35-millimetre external bottom bracket system. Hollow forged crank arms and a massive 35 millimeter Praxis spindle cold-forged from 7075 aluminum make this the absolute stiffest BMX race crank on the market today, period.

A precision CNC-machined chromoly/alloy self-extracting crank bolt system round out the system, making installation and removal a snap. Fits frames with BB30/PF30 bottom shells. M35 cranks will not fit frames with BSA (Euro), BB86 or T47 bottom bracket shells.
