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 Aramid resin used in this compound extends life hugely, making this our most durable and most advanced grip available. The Lock-On grips are designed to ride faster, jump further and last longer.
