Mavic Cosmic SLR 45 SI-CL700 Carbon UST Wheelset - Centerlock - 12x100mm | 12x142mm - XDR

Perfect balance between dynamic, reactivity and stability.

The new Cosmic SLR 45 isn't just an update—it's a complete redesign of the most versatile wheel. With its 23mm wide inner rim and ceramic bearings, it's the go-to choice for cyclists looking to maximize their performance on any terrain.

It’s lighter, more stable in crosswinds (Aero Wide Rim / Aero Spokes), and incredibly responsive thanks to the absence of a rim floor (Fore Carbon). It offers predictable handling and instant power transfer. Whether you’re sprinting or climbing, it turns every pedal stroke into pure acceleration.

The Cosmic SLR 45 turns your bike into a highly efficient racing machine, regardless of the route's profile.

Technologies of the Mavic Cosmic SLR 45 Disc Carbon

Aero Wide Rim Technology: unmatched combination of speed, control and comfort

The technology: An aerodynamically optimized tread pattern for tires ranging from 28 to 30 mm (internal width 23 mm).
The concrete effect: The tire is better supported, preventing the “balloon effect.” Downhill tracking is more precise, and crosswinds are neutralized, allowing you to stay in the aero position longer even in variable wind conditions.
The added value: Greater comfort and grip without compromising aerodynamics.

Fore: stiffer, longer lasting rim-spoke connection with practical Tubeless advantages

The technology: The spokes are anchored directly into a metal insert integrated into the carbon shell, ensuring that the upper rim edge remains intact.
The concrete result: You get a rim that is 40% more torsionally rigid. On the road, this means there is absolutely no lateral instability during explosive accelerations.
The added value: No rim flange. You eliminate the risk of leaks, save weight on the tires, and make tire installation easier. It is the most reliable tubeless solution on the market.

Adaptive Layup Carbon Technology

Optimized carbon layup for a tailored combination of lightness, stiffness, and flexibility.

Instant Drive 360 Technology

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

Infinity Hubs Technology

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