Flat Mount Klamper

Description |

We think this is the best mechanical disc brake on the market, machined by Paul in Chico, California. Flat-Mount Klampers are available in Short-Pull (SRAM/Shimano), Long-Pull, or Campagnolo Pull.

It took 3 years of in-house development before the Klamper met all of Paul's extremely high goals. They wanted absolute reliability, easy adjustability, and field serviceability. Paul also wanted super strong stopping power but without hydraulic fluid and fussy bleed kits. After countless drawing revisions, fine tuning of piston design and bearing ramp profiles, and probably 20 prototypes, Paul nailed it, and the Klamper has quickly become a cult classic.

What’s the secret sauce? They don’t want to give away all of their engineering secrets, but the bulk of the power comes from using oversized ball bearings, and machining pistons from 12L14 steel. Using this steel alloy allows to heat treat the pistons which also hardens the bearing ramp races to resist pitting for a lifetime of silky smooth lever pull. Using flat needle roller thrust bearings instead of a plastic thrust washers doesn’t hurt either.

These brakes are perfect for long mileage deep wilderness bike touring where field serviceability with nothing but a good multitool is crucial to getting back to civilization alive. They’re also great on cyclocross race bikes where tool free independent pad adjustment and a simple cable barrel adjuster means you can fine-tune brake feel specific to course and conditions. We constantly see them on custom built steel hardtails and gravel grinder shred sleds where a rider wants the proven quality of as many American made components as possible.

As always, allow a couple short rides to bed in the pads. Around the 3rd ride, these brakes really start to BITE!
