MAVIC Cosmic SL 45 Disc 28"/700C Road Bike Rear Wheel SRAM XDR™

Aerodynamics, efficiency and versatility.
The Mavic Cosmic SL 45 Disc rear wheel is a high-quality carbon wheel for ambitious road cyclists who value speed, comfort and versatility. With its wide UD carbon rim, it offers an optimum combination of aerodynamic efficiency and riding stability.

The 45 mm high and 32 mm wide rim noticeably reduces air resistance and, in conjunction with the Mavic Aero spokes, ensures improved aerodynamics, which has been tested in the wind tunnel. This allows you to put more watts on the road with the same amount of power.

Thanks to the high-quality INFINITY hub with its Instant Drive 360 freehub system and smooth-running QRM auto bearings, your power transfer is particularly efficient. The wheel reacts quickly and directly, which makes for a noticeably more agile riding experience.
Its balanced construction makes the Cosmic SL 45 Disc one of the most versatile carbon wheels from Mavic. The lightweight rim and precise spoking not only guarantee low weight, but also stability and reliability on long tours and in racing.

Whether flat sprints, hilly stages or intensive training sessions – the Mavic Cosmic SL 45 Disc system wheel impresses with aerodynamic advantages, high stiffness and exceptional versatility.


Top technologies:
• Aero Wide Rim Technology: Less drag, more watts thanks to the aerodynamic rim profile developed by our aero experts and tested in the wind tunnel.
• ID 360 Instant Drive: A lightweight and low-friction Dual Ratchet freewheel system for explosive propulsion and reliable power transmission. 
• UST tubeless technology: The Mavic standard for tubeless tyres not only improves traction, comfort and rolling resistance, but also reduces the risk of tyre defects.
• QRM Auto (Qualité de Roulements Mavic Auto): Smooth-running, double-sealed and maintenance-free industrial bearings with high dimensional accuracy and self-adjusting bearing preload.
