  • I.S. Klamper

    Three years of development and we think we nailed it. 100% designed, tested and manufactured in house. Click on “Short Pull, Long Pull or Campagnolo?” in the Technical Information below if you are unsure of which to order.

    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. Just change the actuating arms, which are available separately here.

    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.

    Technical Information
    • Material: 6061 Aluminum, Heat Treated 12L14 Steel
    • Weight: 211g
    • Finish: Anodized or Polished
    • Anodized Color: Black, Silver or High Polish
    • Cable Pull: Short Pull, Long Pull or Campagnolo
    • 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.
    • Brake Pads: Kool Stop Disc Brake Pads

  • Tipp
    Hint for breaking-in:
    New disc brake pads require a certain break-in period in order to provide the full brake power.
    The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stop brakings from a medium speed. Attention: the rotors get very hot, do not touch them!
