The very long awaited Box Mini Vector M30M cranks are finally here.
This crankset is the absolute stiffest junior BMX crankset available.
The M30Ms feature 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.
A precision CNC-machined chromoly/alloy self-extracting crank bolt system makes installation and removal a snap. Includes Praxis™ M30 BSA external bottom bracket with precision bearings for frames with Euro BB shells
