If you’re looking for the next big upgrade to your pride and joy then it might be time to consider beefing up your cranks for some additional stiffness, strength and efficiency…

Box’s oversized technology is a philosophy of design and engineering. Its goal is to reduce energy loss to deformation or friction. The results are enhanced control, better acceleration, and increased speed.

Featuring beefy 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.

Box One Cranks utilize an oversized spindle (35mm on the M35 units and 30mm on the M30-M cranks). With the use of an OT Spindle, we have virtually eliminated flex, increased strength, while maintaining a light rigid product. These key traits translate into enhanced performance.

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