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™.

After doing a BMX 'zine for ten years (1987 - 1996) FATBMX made it on the internet. The year was 1998. Here to stay.
