Pinhead's M9 solid axle wheel locks replace 9 mm factory hex nuts to provide wheel security and improved safety. All parts are precision molded and chrome-plated for consistent function and long life. Locks are installed once, using a special coded key, and remain on the bike to lock the wheel to the axle. The same coded key is used to remove a wheel for servicing.
Designed to replace your axle nuts for one axle. Operated using a unique multi combination key, to ensure the security of your wheels at a fraction of their replacement cost.
