BMA Rim Lock 160/275-300

Heavy-duty die cast aluminium body. Moulded rubber flap protects against inner tube abrasion. Ribbed alloy contact surface locks tire securely to rim. Recommended for use on all off-road machines and any application using low tire pressure. Fits between the tyre and the tube, with metal cleats on the bottom to grip the inside of the tyre bead. Prevents a tyre from spinning on the rim under hard acceleration and braking, particularly when a tyre is under inflated. Without a rim lock a valve stem could be torn from the inner tub.
