Another Box crankset engineered and built around their oversized technology, which makes sure that when you push down hard on your pedals that power is actually going to the back wheel and not being wasted.

They feature beefy hollow-forged crank arms and a massive 30mm Praxis M-30 spindle, cold-forged from 7075 aluminium that's precision ground to extremely tight tolerances. The M-30-M Crankset is the absolute stiffest junior race BMX crankset available.

For easy installation and removal the Box One M30-M Crankset features a precision CNC-machined chromoly/alloy self-extracting crank bolt system.
