The Paul Klamper Disc Caliper uses ball bearings in a ramp system to ensure smoothness and increased pad travel. To further enhance durability, hardened steel is strategically placed where the balls make contact with the ramps. Additionally, three hardened steel pins precisely locate the pad actuator. This model is available in both short and long-pull versions, making it compatible with road bike brakes and mountain/linear-pull brake levers, respectively.
