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 worlds 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.

• Praxis M35 external bottom bracket with precision Enduro bearings
