This wheel is engineered for the modern road cyclist who demands versatility and speed on any terrain, from steep mountain climbs to fast, flat sprints. It represents the pinnacle of all-around performance, designed to give you a tangible competitive edge.As Mavic states, Aero efficiency, quick acceleration and the improved ride quality of UST Tubeless. You get it all with this disc-brake specific wheel featuring easier to use Road Tubeless technology and lighter weight. This ethos is built into every aspect of the Cosmic SL 45, making it the ultimate upgrade for your disc brake road bike.Key Benefits:* Accelerate and Climb Faster: The 45mm deep rim profile is lightweight, minimizing rotational inertia for explosive acceleration and effortless climbing. Its refined carbon layup provides the lateral stiffness needed to transfer every watt of power directly to the road, ensuring no energy is wasted when you attack a climb or sprint for the line.* Superior Aerodynamic Performance: Developed using a NACA (National Advisory Committee for Aeronautics) inspired profile, the 45mm deep rim slices through the wind with minimal drag. This advanced aerodynamic design not only makes you faster on flat roads and descents but also provides exceptional stability and predictable handling in challenging crosswinds, boosting your confidence at high speeds.* Enhanced Ride Quality and Control: Embrace the future of road cycling with Mavic´s user-friendly UST Tubeless system. Running lower tire pressures without the risk of pinch flats results in a smoother, more comfortable ride and significantly improved grip in corners. The Fore Carbon drilling technology creates a fully sealed upper rim bridge, eliminating the need for rim tape and making tubeless tire installation simpler and more reliable than ever.Main Features:* A 45mm deep, wind-slicing carbon rim with a NACA-derived profile for low drag and crosswind stability.* Fore Carbon tubeless technology, which requires no rim tape for a perfect air-tight seal and increased rim strength.* The state-of-the-art Infinity hub platform, optimized for disc brake forces, ensuring perfect spoke tension and wheel durability.* Instant Drive 360 (ID360) freehub system provides ultra-fast engagement for immediate power transfer out of corners and during sprints.* Patented elliptical aero spokes that reduce air resistance and enhance wheel stiffness.* A disc-brake specific build engineered to handle the unique stresses of modern braking systems with confidence and power.Technical Specifications:* Category: Wheels and tyres* Subcategory: Wheels* Wheel Position: Rear* Discipline: Road Cycling* Diameter: 28´´- 700* Material: Carbon* Tire Compatibility: Clincher / UST Tubeless Ready* Brake System: Disc Brake (Center Lock)* Rim Depth: 45mm* Internal Rim Width: 19mm* Spoke Count: 24
