The BOX Components "Box Two M30-P" BMX Race Crankset is a two piece crankset from the BOX Oversized line, made for bigger riders. The arms are hollow forged and CNC machined from 7075-T6 aluminum, the 30mm spindle is turned from 7075-T6 aluminum. Arms and spider come from the Box One M35.
The bottom bracket (BSA 30mm, 1.37") is included, so the crank fits a standard Euro shell. The spider takes 4 bolt chainrings with a 104mm bolt circle, and the crank is held by a self extracting crank bolt. Pedal washers are not used on this crank.
