Avid Elixir XO Hydraulic Disc Brake 140mm Rear Red

The Avid Elixir XO Rear Hydraulic Disc Brake is a unisex mountain bike hydraulic disc brake made for legacy SRAM/Avid mountain bikes using the Elixir XO brake platform. This rear brake combines the Elixir XO hydraulic lever and caliper in the red finish from that generation, giving compatible bikes a service replacement that preserves the original control layout. Because Elixir hardware predates current SRAM brake families, hose fittings, rotor size, mounting adapters, fluid type, and service parts should be verified against the exact brake generation before installation. The title indicates a rear assembly intended around a 140 mm rotor setup. It is intended as a straightforward, serviceable component that fits naturally into a well-sorted setup, with compatibility and installation details worth confirming before use.
