  • What is 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.

Product Story

When we set out to build this brake, nearly five 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 included 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!

Replacement pads can be found HERE.

Please note that all of our brakes are sold per wheel.

 🚵This is EPIC riding in some of the most beautiful areas of the #LostSierra. 🏕️Camping, live music, swimming, and partying with your friends, this is one of our favorite events of the year. 
⛏️Every penny raised by registration goes right back into building local trails and supporting the local mountain communities via @sierratrails .
🥓We’ll be there with our 🔥 Aid Station as usual. Paul himself will feed you pickles and bacon out on course. No, really!
📝LETS GOOOOOOO! 🎉

We’ve been offering a front Flat Mount Adapter f We’ve been offering a front Flat Mount Adapter for a few years, so we figured it was about time to make a matching rear. 
  This adapter is +20mm, so good for putting a 160mm rotor on a 140 frame, and also helpful if you need a little more cable housing clearance at the chainstay. We aren’t usually weight-weenies, but after machining a pocket into these they end up at only 9 grams. 
  As usual, these are CNC’d by us to ultra-high tolerance right here in Chico, California. 
  Have a great weekend!
Canti Lever blades fresh out of the tumbler and re Canti Lever blades fresh out of the tumbler and ready for anodizing. As with all of our bearing press-fit features, we hold +/-0.0002” tolerance on these parts. That’s about 5 microns, and for comparison, the average human hair is about 70 microns thick. So yeah, these tolerances are TIGHT is what we’re saying!
Is this weird? Be honest. Is this weird? Be honest.

Going through a folder of photos by @johnprolly fr Going through a folder of photos by @johnprolly from 2018 and we are having some FEELINGS of EXCITEMENT that @downievilleclassic is BACK!🎉 This event is SO much more than a bike race, it’s a big family party with all your bike friends in some of the most beautiful rugged mountains in the #LostSierra. We’ll be bringing back our on-course aid station and breakfast tent downtown to support, and y’all wouldn’t believe how many pounds of bacon and coffee we go through on a weekend like this, it’s wild. Anyways, registration opened Sunday night and rumor has it the fields are filling up pretty quick, so don’t wait to pull the trigger on this, it is hands down the BEST mountain bike party in the USA!
