Replacement insert pads designed to fit cartridge style V-brake carriers. These brake pads are compatible with the Aztec V-type System, Shimano mountain bike cartridge systems, and many other third-party models. They eliminate the need to re-set the brake pad position, allowing you to simply slide out the worn pad and slide in a new one. Featuring a high-performance Aztec compound and design for extended life and all-weather braking power, these pads are specifically engineered for use with alloy rims. They are secured in place by two small split-pins, which are included. Supplied as a pack of two pairs.
