Grin Torque Arm V6

Grin's V6 universal torque arm pairs a hardened 17-4 PH stainless splined insert with a swiveling clamp bracket that mounts to the frame or fork using hose clamps — no fender eyelet required. The splined interface offers roughly 50 rotational positions to match almost any dropout/axle-flat orientation, and inserts for 12 mm, 14 mm, and 16 mm axles are included. A Grin Frame Clamp (sold separately) provides the frame mounting surface.
