Both the rear dropouts are replaceable on the Edit and the Bitmap. It's one of those little extra touches that we felt were important when we designed the frame. If you've somehow managed to damage your brake mount (if you have we'd like to know how, seriously), then we've got you covered with a replacement dropout.
This dropout is compatible with a 142x12mm (Edit v1 & v2) or Boost 148x12mm (Edit v3, Bitmap) Rockshox Maxle rear axle and post-mount type disc brakes. The minimum disc rotor size is 180mm and the maximum rotor size is 203mm (spacer kit required).
