The Mavic Cosmic SLR 45 D CL Rear Wheel features several advanced technologies designed to enhance speed, control, and efficiency. The wheel utilises Aero Wide Rim Technology, which contributes to a combination of speed, control, and comfort. It incorporates Fore Carbon Tapeless Tubeless Technology, resulting in a stiffer and stronger rim. This technology features a fully sealed upper rim bridge, eliminating the need for rim tape, as the spokes are directly screwed into a threaded metallic insert wrapped inside the carbon layups of the lower rim bridge.
The wheel is built around the Instant Drive 360 Technology, which is super light and efficient. This system includes a large contactless rubber seal that provides low friction, and a wide array of end caps for versatility. The Infinity Hub Design ensures an ultra-reliable, high-performance hub with efficient power transfer, thanks to the optimised non-contact spoke lacing and tension distribution. The spoke lengths are identical on both the front and rear wheels.
Mavic's QRM Auto Bearing Preload Technology (Qualite de Roulements Mavic Auto) uses double-sealed cartridge bearings with E3 internal clearance. The preload is automatically adjusted to guarantee a perfect spin with no play over the long run. The UST Tubeless Technology improves traction, control, and comfort while reducing inertia and flats.
