Disc Brake Caliper Mount Adapter 20mm Post Mount for 180mm Brake Caliper

Worked great with my larger rotors

This took my Trek Fuel EX rear brake from 180mm to 200 (or 203). It works great. It would work on the front, too (the bike came with an adapter and a 200 in front).

This worked on my xxx. All the washers are convenient.

So much cheaper than the sram OEM one. Works just as good. Why spend 3x this much for the sram one?

As per title but in the front I had to grind it down a few mm to get full pad contact and in the back I had to shim it to clear the disc edge. I converted Rad Rover 6+ 180mm discs to 203mm and other offset type adapters push the caliper into the seat stay. Nice that it includes the cup shims others didn’t but the 35mm screws were too short to get good thread depth through the thicker end.
