Box One™ M35 Cranks have proven themselves as the go-to choice for elite BMX racers. What makes these BMX cranks so special is that they are the world’s first with a Praxis™ 35-millimeter 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.
 
Only fits frames with BB30/PF30 bottom shells. M35 cranks will NOT FIT frames with BSA (Euro), BB86, BB90, or T47 bottom bracket shells.
