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 adjust ability but staying power. For that we designed detentes 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. We decided not to make rotors. That's a manufacturing process we do not do, and they are readily available. Floating rotors with large buttons (like Hope) might rub against the caliper, but we've had great results with Shimano Ice-Tech, Sram, Avid, and most other rotor brands.

The pads are Kool Stop sintered metallic. As always, allow a couple short rides to bed in the pads. Around the 3rd ride, these brakes really start to BITE! Please note that all of our brakes are sold per wheel. Rotors are not included, however, Kool-Stop sintered metallic pads are included.
