If using SRAM brakes, you’ll want to use part number 00.5318.018.001 (FLAT MOUNT BRACKET FRONT/REAR- 20FD (FLATMOUNT DIRECT), INCLUDES 2 STAINLESS BRACKET MOUNTING BOLTS - RUDY/RUDY XL) to use a 180mm rotor with your 2026+ Rudy XL A1.
If using a third-party brake system, you’ll want to reach out to the brake manufacturer for guidance on which adapter is required.
