Box Five SQ Tapered Cold Forged Klaņi

Featuring a JIS square taper standard, our oversized bottom bracket interface showcases a step-down shape specific to the crank arm length meeting at the pedal boss. Unlike alternative options, no two lengths are the same. Our durable cold-forged cranksets are available in sizes from 135mm through 170mm and employ a 5 bolt 110 BCD chainring pattern.

All JIS square taper standard cranks are compatible with all BSA European style square taper bottom brackets.
