The Mavic Cosmic SLR 45 Disc carbon wheels are the ideal choice for road cyclists looking for speed and efficiency in all situations, including racing. The streamlined 45 mm rim cuts through the air with minimal drag. It's also one of the lightest in its class. For this season, the outer carbon layer benefits from Mavic's new UD² design, which gives it a distinctive visual identity and further reduces the weight of the carbon layer: 15 g saved on each rim
!
The combination of the new layering technique used to manufacture the rim and Mavic's exclusive Fore Carbon technology means that the upper deck is left intact and the rim is reinforced only at critical points. The result is a 40g lighter wheel. As the spokes are anchored without drilling the upper bridge, there's no need for a rim tape, which means additional weight savings (30 g), and fewer problems when fitting or repairing tubeless tires. With the new profile of the rim top bridge, mounting and demounting a tire has never been so easy. With the UST Tubeless system, no tubes, no friction. And greater air volume means smoother handling. The result: greater speed, with greatly reduced rolling resistance. And last but not least, Mavic's patented elliptical spokes save even more energy, while
Mavic's new Infinity hub platform optimizes spoking. Carefully adjusted spoke tension optimizes power transfer. Their Instant Drive 360 freewheel body, combined with QRM Auto automatic bearing adjustment, guarantees fast engagement, high rigidity and extended durability. The wheels can be fitted with Shimano and SRAM XD-Road freewheel bodies, and are convertible to Campagnolo by means of an optional freewheel body. They are compatible with Center Lock brake discs only. These wheels are designed, manufactured and patented by Mavic in Annecy, France, and entirely handcrafted on their European site.
Product advantages
- Faster acceleration, quicker climbs, better speed retention: Mavic's new UD² layup technique and Fore Carbon spoke anchoring technique save 55g and eliminate the need for a rim tape (another 30g less per wheel). NACA rim profile 45 mm high/26 mm wide optimized for disc brakes Patented lightweight aerodynamic spokes.
- A stiffer wheel for better power transfer: Fore Carbon technology guarantees the strength of the rim's upper bridge, enhancing its rigidity. Infinity hub platform: a rigid axle, durable bearings and a new hub design optimize spoke layout and tension. ID360 freewheel body for instant power transfer.
- The optimized UST Road system provides more speed, more comfort and better handling, all with an easy-to-use tubeless system: no inner tube means less friction, greater efficiency and grip, and better protection against punctures. The profile of the rim's upper deck facilitates tire mounting and changing. Fore Carbon drilling technology eliminates the need for a rim base.

Technologies
- Fore Carbon tubeless technology without rim tape: stiffer and stronger. Instead of drilling the rim to anchor the spokes and fit the nipples, a threaded metal insert is integrated into the draping of the rim's lower bridge, enabling the spokes to be screwed in directly. The upper rim bridge remains intact. No need for a rim base to ensure a watertight seal!
- UST Tubeless technology: traction and control Universal Standard for Tubeless. Ready-to-ride tubeless system. The UST system improves traction, control and comfort, while reducing inertia and the risk of punctures.
- Instant Drive 360 freewheel system: the new Instant Drive 360 freewheel system is ultra-light and efficient. An oversized non-contact rubber seal reduces friction to a minimum, and a wide choice of adapters makes it compatible with all types of frames and axles.
- QRM Auto bearing adjustment technology: Mavic Auto bearing quality Our latest innovation. These cartridge bearings are, of course, double-sealed, with C3 internal clearance. Their preload adjusts automatically to ensure perfect, long-term rotation without any play.
