SRAM Post Mount Brake Adapter Black, 20mm, Post Mount

We've been there with you, trying to up our game on the descents just to find we need bigger brake rotors to make it happen. Whether we need to go from a 160mm to a 180mm or a 200mm to 220mm rotor these post-mount adapters will work with any post-mount caliper front or rear and include all the mounting hardware to install them. These adapters from SRAM even come pre-coated with a blue thread locker so our brakes don't rattle loose down the next black-diamond send.
