Details

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, the Box One™ M30-M Crankset is the absolute stiffest junior BMX crankset available today. A precision CNC-machined chromoly/alloy self-extracting crank bolt system makes installation and removal a snap.

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™.


Includes:
  • Praxis™ External BSA Bottom Bracket
  • M30 BB installation tool

Notes:
  • 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-M cranks were designed to be used without pedal washers.
