• Cosmic SLR 45 Disc 23mm

With its wider 23mm UD2 carbon rim, the Cosmic SLR 45 Disc 23 is the best-performing road wheel ever designed by Mavic. Not only does the 45mm airfoil rim slice through the wind with minimal drag, but it's also amongst the lightest in its category. The external carbon layer features Mavic's UD2 construction for a distinctive look and an even lighter rim laminate, saving another 15g per rim. This wheelset weighs in at only 1482g.

Enhanced aerodynamics

• Mavic's new UD2 rim laminate and Fore Carbon spoke attachments save weight and eliminate the need for rim tape.
• Less drag, more watts thanks to its 45mm rim profile and elliptical spokes developed by our aero experts.
• Patented lightweight aero spokes are featured.

Faster than ever

• Fore Carbon Technology keeps the rims upper bridge solid and secure and creates a stiffer rim.
• Optimised lacing and spoke tension from Mavic's Infinity hub platform with stiff axles and durable bearings
• ID360 freewheel technology for instant power transfer

A more agile ride

• No tubes means less friction, improved efficiency and grip with reduced risk of punctures
• The rim's reduced inertia means instant acceleration and perfect power transfer.

Weight

• Pair: 1482g
• Rear: 806g
• Front: 676g

ADDITIONAL INFORMATION

A new rim laminate coupled with our exclusive Fore Carbon technology leaves the upper rim bridge intact and reinforces the rim only where needed, saving 40g per rim. The spokes attach to the rim without any need to drill the upper rim bed, so no rim tape is required. That means more weight savings (30g) and less hassle when it comes to set up or repair tubeless tyres. The new shape of the rim bed makes it easier than ever to mount and remove tires. UST Tubeless setup 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. At last, our patented elliptical spokes save another 5 watts.

Our new Infinity hub platform optimizes the spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 freewheel with automatic bearing preload adjustment (QRM Auto) provides fast engagement, high stiffness and added durability. It's available for Shimano and SRAM XD-Road driver bodies and can convert to Campagnolo with an optional driver body. It's compatible with a 12x100 axle up front, and 12x142 rear, and converts to Quick Release with supplied adapters. For Center Lock disc rotors only.

These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.

Technologies

Fore Carbon tapeless tubeless technology

Stiffer and stronger. A fully sealed upper rim bridge eliminates the need for rim tape. The spokes are directly screwed in the insert. A threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge.

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.
