The Mavic Cosmic SL 45 Carbon Disc wheels strike a perfect balance between aerodynamic efficiency, lightweight construction, and everyday versatility—making them an ideal choice for road cyclists who demand performance across flat terrain, rolling hills, and climbs alike. Featuring a 45mm deep unidirectional carbon rim and a widened 23mm internal width, the SL 45 is engineered to reduce drag while improving ride comfort and tire volume. Optimized for tubeless use with Mavic's UST system, the hookless design allows lower tire pressures, enhancing control and reducing rolling resistance. With a total wheelset weight of just 1555g (720g front, 835g rear), these wheels offer climbing capability without sacrificing speed on the flats. Front and rear wheels are sold separately.

Responsiveness is at the core of the Cosmic SL 45's design. Mavic's INFINITY hub platform maximizes power transfer for instant acceleration, while steel extra-flat spokes reduce air turbulence and increase lateral stiffness. The 2-cross lacing pattern provides a balance of strength and comfort, and ABS locking nipples ensure long-term spoke tension stability. Compatible with 12x100 front and 12x142 rear thru-axles—and convertible to quick release with optional adapters—the SL 45 adapts seamlessly to most modern road bikes. Center Lock disc compatibility ensures precise, consistent braking in all conditions.

Built for both performance and reliability, the SL 45 features sealed QRM Auto cartridge bearings that self-adjust for durability and smooth operation with zero maintenance. The INFINITY aluminum hub body is lightweight, durable, and supports Shimano HG road freehub systems. Delivered with rim tape pre-installed, UST valve, axle adapters, and a multifunction adjustment wrench, the Mavic Cosmic SL 45 Carbon Disc wheels are ready for fast training rides, race-day action, and long-distance epics. Whether you're sprinting into a breakaway or climbing toward a summit finish, these wheels deliver aerodynamic advantage and all-around excellence.
