SRAM CenterLine X Disc Brake Rotor - 140mm, Center Lock, 1.85mm, Includes Internal Tooled Lockring

The SRAM CenterLine X is a 140mm Center Lock disc brake rotor built with a two-piece design that pairs a lightweight carrier with a steel braking track. The construction saves weight and improves heat management compared to a one-piece rotor, keeping braking consistent on long descents. The CenterLine track shape reduces noise and vibration for smooth, quiet braking. At 1.85mm thick it suits SRAM road and gravel brakes, and this version includes an internal tooled lockring for thru-axle hubs. The 140mm size is commonly used on the rear of road bikes.
