The Mavic Cosmic SL 65 Carbon Disc wheels are built for aerodynamic speed and all-out performance on flat to rolling terrain. Featuring a 65mm deep unidirectional carbon rim and a 19mm internal width, this wheelset is optimized for reduced drag and stable handling in crosswinds. The rim profile was developed through extensive wind tunnel testing, making it an ideal choice for breakaways, time trials, and high-speed road racing. Despite its aerodynamic stature, the rim's reduced rotational inertia ensures quick acceleration and snappy response when the pace ramps up. Weighing in at just 1649g for the set—720g front and 882g rear—the wheels are sold individually for tailored upgrades.

Power transfer is amplified by Mavic’s INFINITY hub platform, which delivers stiffness and efficiency for responsive sprinting and consistent handling. The wheels are laced with extra-flat, straight-pull steel spokes using a 2-cross pattern for optimized strength and comfort. ABS locking nipples help maintain long-term spoke tension, while Center Lock compatibility ensures precise disc brake engagement. The tubeless-ready UST system simplifies tire setup and allows lower pressures for improved traction and reduced rolling resistance. Riders can run modern road tubeless tires or standard clinchers with equal confidence.

Durability and ease of maintenance are at the core of the Cosmic SL 65’s design. QRM Auto sealed cartridge bearings self-adjust for longevity and smooth rolling without the need for manual preload adjustment. The lightweight aluminum hubs are compatible with Shimano HG freehubs and include axle adapters for broader bike compatibility. Delivered with rim tape, UST valves, adapters, and an adjustment tool, the SL 65 is race-ready out of the box. Whether sprinting into the wind or hammering solo off the front, these wheels deliver unmatched aero gains with responsive, road-proven handling.
