These high performance, Taiwanese rollers were purposely engineered for racing. Each individual roller comes with a patented self-lubricated material for smooth shifting at all times. A special formula PA-66 material resists heat for less wear and tear. Different roller weights can be applied to modify performance for variables such as rider weight, riding style and/or terrain. We recommend high-rev engines use lighter roller weights while high-torque engines use heavier roller weights.
