This Cosmic SL 45 rear wheel from Mavic is engineered for performance-driven road cycling, featuring a 45 mm carbon rim that seamlessly integrates modern tubeless technology, disc-brake compatibility, and SRAM drivetrain support. The medium-depth aerodynamic profile strikes the perfect balance between speed, stability, and responsive handling, making this wheel ideal for racing, fast road rides, and diverse terrains. Its UST tubeless construction accommodates both compatible tubeless tires and standard inner tubes, while the SRAM XDR freehub body is designed for use with compatible 12-speed SRAM road cassettes. The Instant Drive 360 freewheel system ensures quick engagement during acceleration, and the Center Lock interface is tailored for compatible disc brake rotors. The wheel is fitted with a 12 x 142 mm rear axle and includes an adapter for conversion to a compatible quick-release setup.
