The Answer Mini Race crank arms are precision CNC machined from 7075 aluminum with deep grooves on the back of each arm to help shed weight without sacrificing strength or stiffness. Includes a removable machined 5-bolt 110mm BCD spider gear. Works with square tapered spindles only.

Rider weight limit is 100lbs on ALL crank arm lengths

This package is arms-only, so you’ll need a spindle and BB set.
