World Championship winning 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 for BMX frames with BB30/PF30 bottom bracket shells. Oversized 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. All sizes include a 4 bolt 104 BCD spider with an anti-flex ring. A precision CNC-machined Chromoly/alloy self-extracting crank bolt system round out the system.
Note: Fits frames with BB30/PF30 bottom shells. M35 cranks will NOT FIT frames with BSA (Euro), BB86, BB90 or T47 bottom bracket shells. Does NOT include drive side bottom bracket seal.
