The Promax SQ-1 Cranks Arms have a traditional, five-arm, 110-bolt pattern spider and come in a variety of lengths to fit most riders or riding situations, from the 5-and-under BMX racer to the 6-foot tall fixie-riding hipster.
Compatible with any JIS square-taper bottom bracket, they are cold-forged from 6061-T6 aluminium for strength, low weight and durability and feature a beautiful anodised finish.
