The Torque Arm V5 is a universal design from Grin that secures both 12mm and 14mm ebike axles against spinout, and works with both front and rear dropouts that have fender eyelets.

This design evolution came about from extensive lab testing and is many times superior to our V2 eyelet torque arms. The splined insert allows for versatile installation angles and is made of a specially hardened 174 Stainless Steel alloy that provides over double the spinout strength of regular steels. Where other torque arms smear apart, this V5 arm holds tight.
