MAVIC COSMIC SLR 45: THE PERFECT BALANCE BETWEEN DYNAMISM, RESPONSIVENESS, AND STABILITY
Mavic DNA: Uncompromising performance
The new Cosmic SLR 45 is not just an update; it is a complete re-engineering of the most versatile wheel. With its 23 mm internal width rim and ceramic bearings, it is the go-to wheel for cyclists looking to optimize their performance on all terrains. Lighter, more stable in crosswinds (Aero Wide Rim/Aero Spokes), and incredibly responsive thanks to the absence of a rim base (Fore Carbon), it offers predictable handling and immediate power transfer. Whether you're sprinting or climbing a hill, it transforms every pedal stroke into pure acceleration.
The Cosmic SLR 45 transforms your bike into an ultra-efficient racing machine, whatever the profile of your ride.
Main features
Premium material, premium performance
The technology: Integration of high-precision ceramic balls for minimal friction.
The concrete effect: A reduction in friction of up to 28%. Beyond the figures, it is a feeling of fluidity that persists kilometer after kilometer, particularly noticeable on flat sections at high speed where inertia is preserved for longer.

Unmatched combination of speed, control, and comfort.
The Technology: An aerodynamic profile optimized for 28 to 30 mm tires (23 mm internal width).
The Concrete Effect: The tire is better supported, avoiding the "balloon" effect. The trajectory is more precise on descents and crosswind drag is neutralized, allowing you to stay in the aero position longer, even in unstable winds.
Added value: Increased comfort and grip without sacrificing aerodynamic drag.

Added value: Increased comfort and grip without sacrificing aerodynamic drag.
Greater rigidity
The technology: The spokes are anchored directly into a metal insert integrated into the carbon weave, leaving the upper rim bridge intact.
The concrete effect: You get a rim that is 40% more torsionally rigid. On the road, this translates into a total absence of lateral blur during explosive accelerations.
The added value: No rim base. You eliminate the risk of leaks, save weight on the periphery, and make tire mounting easier. It's the most reliable tubeless solution on the market.

“Got these wheels recently and had the chance to test them and I couldn't be happier. They are extremely fast and you can tell by the way the bike rolls on downhill”

“Paire de roue légère, rigide et très aérodynamique, j'ai monté un pneu Tubeless de 28 mm à l'avant et 30 à l'arrière, un jeu d'enfant avec son fond de jante non percé, super confort en limitant la pression à 4 bars. Des roues vraiment polyvalentes en toutes circonstances, très content de mon achat. ”
