Paul Component Klamper - Short-Pull - Flat Mount - Road - Mechanical Disc Brake - all black

Mechanical disc brake caliper made of CNC-milled 6061 aluminium with short-pull actuation. When Paul Component set out to build this brake, nearly three years ago, they started with a clean slate. Then they tried all manner of whacky ideas but eventually wound their way back to the tried and true ball bearing in a ramp system. From there Paul Component concentrated on the details. They made the balls bigger for smoothness and increased pad travel and hardened the steel where the balls contact the ramps. Three hardened steel pins were used to locate the pad actuator. Instead of a plastic thrust washer Paul Component used a flat needle roller thrust bearing.
Then Paul Component moved onto the caliper body. This took countless drawing revisions and probably 20 prototypes. They added “fangs” to the inner backing plate for stiffness, and beefed up the outer caliper body where needed.
The pad adjusters went through a similar process. Paul Component wanted easy adjustability but staying power. For that they designed detents into the circumference, located with spring ball plungers.

Paul Component believe this is the best mechanical caliper ever made for a bicycle. It’s available in long pull and short pull, just change the actuating arm, both of which are available separately.
