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™.
