COSMIC SLR 45 SILVER

Main features

Mavic Ceramic: Premium smoothness, world-class performance

With high-end ceramic bearings, Mavic pushes watts optimisation to the next level. Naturally smoother and more durable, ceramic bearings, combined with low-density grease and ultra low-friction seals, deliver faster, more efficient rotation ride after ride. Paired with the fast-engaging ID360 freewheel system, every input is translated instantly into forward motion. This technology maximizes every watt you put in. The result: an exceptionally smooth ride feeling, enhanced durability, and consistent performance even in the most demanding conditions.

Built wider to go faster, smoother, and with total confidence

Engineered for maximum efficiency, the wider rim profile creates a seamless transition between rim and tire to reduce drag and eliminate micro-turbulence, while optimized aero spokes further minimize aerodynamic losses. Together, they lower rolling resistance, enhance airflow stability, and ensure predictable handling in crosswinds. By refining the tire’s contact patch, the system also enables lower pressures, delivering increased comfort and a smoother, faster ride on any surface.

FORE Technology: When performance meets ease of use

Mavic’s FORE technology creates a strong, precise connection between the rim and the spokes by screwing them directly into the rim at an optimal angle, eliminating unwanted movement and improving stiffness and long-term reliability. This is further enhanced by the Adaptive Layup construction, where strategically placed carbon reinforcements strengthen the rim while reducing its weight. By leaving the upper rim flange unpierced, this design also ensures a perfectly airtight structure, making tubeless setup faster, easier, and more reliable. The result: maximum power transfer, an optimized strength-to-weight ratio, and minimal maintenance.

Key technology

Efficiency RigidityAero Wide Rim Technology
Unmatched speed, control, and comfort combo.
LightnessAdaptive Layup Carbon technology
Optimized carbon layup for tailored combo of lightness, stiffness and compliance
Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
