Mavic Cosmic SL 45 Carbon Disc 700c Front Wheel

With its widened 23mm UD carbon rim, the Cosmic SL 45 is the most versatile of Mavic's carbon wheels, with improved comfort and performance. New spokes and hubs give the Cosmic SL 45 Disc a light and lively feel for climbing and accelerating.

Aero efficiency, quick acceleration and the improved ride quality of UST Tubeless. You get it all with this disc-brake specific wheel featuring easier to use Road Tubeless technology and lighter weight.

The rim is engineered with a NACA rim profile that's 45mm deep and 23mm wide, designed specifically for all-rounder performance on flat or hilly terrain. The rim bed shape makes it easier than ever to fit tubeless and tube-type tyres. Riding UST Tubeless means no tube, so no friction, and more air volume means a smoother ride. The result is a faster ride with super low rolling resistance. Refined spokes make this wheelset 80g lighter than its predecessor, the Cosmic Pro Carbon UST Disc. Combined with the Infinity hub platform, which makes the wheels feel quick and responsive out of every corner, they are stiffer and more efficient.

This Cosmic SL 45 Disc is engineered specifically for disc brakes, with an optimised spoke count and lacing. They are offered in CentreLock only and are compatible with 12mm thru-axles and can convert to quick release with included adapters. They are available for Shimano cassettes and convert to SRAM XD-R or Campagnolo with an optional driver body. These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in Mavic's European carbon factory.

Instant Drive 360 Technology

Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.

UST Tubeless Technology

Traction control. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats

Infinity Hub Design

An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.

QRM Auto Bearing Preload Technology

Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.

Improved Aerodynamics

• 45mm NACA inspired rim shape minimises drag for added speed
• Less drag, more Watts thanks to its 45mm rim profile and flat spokes developed by Mavic's aero experts and wind tunnel tested
• Reduced inertia of the lightweight rim delivers instant acceleration

Versatile Performance for All Road Riding Conditions

• Minimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types of terrain, from the flats to mountain climbs
• Disc-brake-specific build for improved control and compatibility with 12mm thru axles

Unrivalled Versatility

The lightness of its 23mm rim and its spoking make the Cosmic SL 45 Disc the most versatile Mavic road wheel ever designed.
