MAVIC COSMIC SLR 45: THE ABSOLUTE BALANCE BETWEEN DYNAMISM, RESPONSIVENESS, AND STABILITY The DNA of Mavic: Performance without compromise The new Cosmic SLR 45 is not just an update; it's a complete re-engineering of the most versatile wheel. With a 23 mm internal width rim and ceramic bearings, it stands out as the centrepiece for cyclists looking to maximise their efficiency on all terrains. Lighter, more stable against side winds (Aero Wide Rim / Aero Spokes) and incredibly responsive due to the absence of rim tape (Fore Carbon), it provides predictive handling and instant power transfer. Whether you're sprinting or climbing a hill, it turns every pedal stroke into pure acceleration. The Cosmic SLR 45 transforms your bike into an ultra-efficient racing machine, no matter the profile of your ride. Main Features Mavic Ceramic: premium material, premium performance The Technology: Integration of high-precision ceramic balls for minimal friction. The Concrete Effect: A claimed friction reduction of up to -28%. Beyond the numbers, it's a sensation of smoothness that persists mile after mile, particularly noticeable on flat sections at high speed where inertia is maintained longer. Aero Wide Rim: Unmatched combination of speed, control, and comfort. The Technology: An aerodynamic profile optimised for tyres of 28 to 30 mm (internal width of 23 mm). The Concrete Effect: The tyre is better supported, avoiding the 'balloon' effect. The trajectory is more precise in descents and side wind resistance is neutralised, allowing you to stay in an aero position longer, even in unstable winds. The Added Value: Improved comfort and grip without sacrificing aerodynamic drag. FORE: More stiffness and a sealed system for Tubeless. The Technology: The spokes are anchored directly into a metal insert integrated into the carbon layup, leaving the upper bridge of the rim intact. The Concrete Effect: You achieve a rim that is 40% stiffer in torsion. On the road, this translates to zero lateral blurring during explosive accelerations. The Added Value: Zero rim tape. You eliminate the risk of leaks, reduce peripheral weight, and make tyre installation easier. It's the most reliable tubeless solution on the market.
