Renthal Lock-On grips feature CNC aluminium locking collars, permanently integrated with the central core, giving the ultimate all-weather security on the handlebar. The integrated construction eliminates any movement between the grip section and the collars, which could otherwise develop over time. The Traction grip pattern was designed to give ultimate control in all conditions. The additional mechanical grip of the Traction pattern means that you can retain control, no matter what the weather might throw at you.
