Grin Torque Arm V7 Regen (M12)

Options

Axle Size

Grin's V7 Regen torque arm for M12 axles — a machined, 11 mm thick 17-4 PH stainless block with a 25-tooth splined arm and a dual Grade-12 bolt clamp that delivers over 1,500 lb of clamping force. It is purpose-built for regenerative-braking hub motors, whose alternating torque tends to wiggle axle nuts loose; the active axle clamp eliminates that play. Must be installed on a solid (non-cabled) axle for full strength, and requires a Grin Frame Clamp (sold separately).

In brief: Torque arm. Fits M12 axles. From $58.
