Mavic Cosmic SLR 45 Rear Wheel - 28" | Carbon | Clincher | Centerlock | UST - 12x142mm - SRAM XDR

The Cosmic SLR was designed for riders who demand more, combining speed, stability, and precision to turn every ride into a true performance experience.

Mavic Ceramic: Exceptional Smoothness, World-Class Performance

With high-quality ceramic bearings, Mavic sets new standards in performance optimization. The ceramic bearings - which are inherently smoother and more durable - combined with low-friction grease and extremely low-friction gaskets ensure faster and more efficient rotation, ride after ride. Together with the quick-engaging ID360 freehub system, every effort is instantly converted into forward momentum. This technology gets the most out of every watt. The result: an exceptionally smooth ride, increased durability, and consistent performance even under the toughest conditions.

Wide design for higher speeds, smoother rides, and absolute confidence

The wider rim profile ensures maximum efficiency and a seamless transition between the rim and tires, reducing drag and eliminating microturbulence. Optimized aero spokes further minimize aerodynamic losses. Together, they reduce rolling resistance, improve flow stability, and ensure predictable handling in crosswinds. By optimizing the tire’s contact patch, the system also allows for lower tire pressures, delivering greater comfort and a smoother, faster ride on any surface.

FORE technology: Where Performance Meets User-Friendliness

Mavic’s FORE technology ensures a strong and precise connection between the rim and the spokes by screwing them directly into the rim at an optimal angle. This eliminates unwanted movement and improves stiffness and long-term reliability. The Adaptive Layup construction—in which strategically placed carbon reinforcements strengthen the rim while reducing its weight—further contributes to this. Since the upper rim flange is not drilled through, this design also ensures a completely airtight structure, enabling faster, easier, and more reliable tubeless installation. The result: maximum power transfer, an optimized strength-to-weight ratio, and minimal maintenance.

Technologies of the Mavic Cosmic SLR 45 rear wheel

Instant Drive 360 freewheel technology

The Instant Drive 360 freehub system is extremely lightweight and efficient. A large, non-contact rubber seal ensures low friction, while a wide range of end caps makes it extremely versatile.

Aero Wide Rim Technology

The ideal combination of stiffness and efficiency for maximum speed.

Adaptive Layup Carbon Technology
Optimized carbon layup for a tailored combination of lightness, stiffness, and compliance.

UST tubeless technology

Traction and control. Universal standard for tubeless. Ready-to-ride tubeless system. The UST concept improves traction, control, and comfort while reducing inertia and the risk of flat tires.

Infinity Hub Design

Efficient power transfer thanks to optimized contactless spoke lacing (no noise under load) and tension distribution. The length of the front and rear spokes is identical. Maintenance is easy thanks to a tool-free solution.

QRM Auto-Bearing Preload

These cartridge bearings are double-sealed and feature a C3 inner clearance. Their preload is automatically adjusted to ensure smooth, play-free running over long distances.
