    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.

  • • Box Two M35 bottom bracket
  • No. These cranks are designed to not use pedal washers. Installing pedal washers can damage the crank as the pedal will not be threaded in sufficiently.

    No. Box M35 cranks will only fit frames with BB30 or PF30 bottom bracket shells?

    Yes. The bottom bracket is designed to only require a dust seal on the non-drive side.

    No. A chainring can only be installed on the inside of the spider.

    No. A loose pedal will damage the crank and can cause injury. Always ensure that your pedals are tightened correctly.
