Product Story

This +20mm Rear Flat Mount Adapter is for running 160mm rotors on a 140mm frame. It could also work for putting a 140 rotor on a 120 frame, or a 180 rotor on a 160 frame, you get the idea. We don’t normally care that much about being ultra-light, but we did machine out a little hollow section, so this adapter only weighs 9 grams, so that’s cool.

This kit comes with the screws that hold the brake to the adapter, but you’ll still need to find the right length screws to mount the adapter to the frame. Since those can vary quite a bit in length depending on the frame, those are sold separately HERE.

We sell matching Front Flat Mount Adapters HERE.

Did you know that Chico’s annual Bidwell Bump mo Did you know that Chico’s annual Bidwell Bump mountain bike race predates the first Repack?! 
  It’s a beautiful rugged loop with a creek crossing in Upper Park, and registration is still open for this year’s October 5th running. Head over to @bikereg and type in Bidwell Bump to get in on this historic race, and all proceeds go to Velo Trail Works. 
  Also, if you want to read a hilarious recounting of the first race in 1976 by local legend Chuck Bodfish (keep in mind, mountain bikes weren’t really invented yet), head over to the PAUL Comp website and type “Bidwell Bump” into the search bar.
