PROMAX - SQ-1 CRANK ARMS

SQ-1 Crank Arms

The 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 aluminum for strength, low weight and durability and feature beautiful anodized finishes.

Available in anodized red, blue, gold and black with laser-etched graphics in lengths 135 to 170 in 5-millimeter increments. Bottom bracket sold separately. Meets or exceeds ENBMX standards.
