Featuring oversized hollow-forged crank arms and a massive 30-millimeter Praxis™ M-30 spindle cold-forged from 7075 aluminum and precision ground to extremely tight tolerances, Box Two™ M30-P cranks fit frames with European bottom brackets, paired with the same oversized, hollow-forged arms and 104 BCD spider as our Box One™ M35 cranks. An independent test lab compared a wide range of cranks to both the Box One™ M35 and Box Two™ M30-P cranks. The Box Two™ M30-P cranks proved to be stiffer than anything on the market, being second only to its Box One™ M35 big brother.

Each crankset includes a Praxis™ M30-BSA Threaded Bottom Bracket that is compatible with all BSA European style bottom brackets. For frames with BB86 or BB30/PF30 bottom bracket shells, compatible adapters can be purchased separately from Praxis ™.

  • BB86 frames require Praxis™ part 86-4001B
  • BB30/PF30 frames require Praxis™ part 68-4001R or 68-5401R
  • T47 frames require Praxis™ part 47-0000
  • Do not use pedal washers when installing pedals onto these cranks. M30-P cranks were designed to be used without pedal washers.
