PAUL Post Mount/I.S Klamper Disc Brake Caliper
*** CONTACT US FOR MORE COLOURS/OPTIONS INCLUDING LIMITED EDITIONS ***
Three years of development and we think we nailed it. 100% designed, tested and manufactured in house.
When we set out to build this brake, nearly four years ago, we started with a clean slate. Then we tried all manner of wacky ideas but eventually wound our way back to the tried and true ball bearing in a ramp system. From there we concentrated on the details. We made the balls bigger for smoothness and increased pad travel. We hardened the steel where the balls contact the ramps. We used three hardened steel pins to locate the pad actuator. Instead of a plastic thrust washer we used a flat needle roller thrust bearing.
Then we moved onto the caliper body. This took countless drawing revisions and probably 20 prototypes. We 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. We wanted easy adjustability but staying power. For that we designed detents into the circumference, located with spring ball plungers.
We believe this is the best mechanical caliper ever made for a bicycle. It’s available in Long Pull, Short Pull, and Campagnolo pull.
Short Pull: This version is designed to work with road levers, including SRAM, Shimano and combined shifter/brake levers. It also works great with the Canti Lever, our short-pull flat bar brake lever.
Long Pull: This version is designed to work with long-pull brake levers, such as the kind that work with V or linear-pull brakes. Our Love Levers work especially well with this model. It also works well with long-pull drop bar levers, such as the Cane Creek Drop V.
Campagnolo: Campy uses a super-short cable pull, so this Klamper uses a super short Campy-only actuator arm.
