Mavic Cosmic SLR 45 Disc 29/28" (622 mm) Disc Brakes 12x100-12x142 Shimano HG Center Lock Front Wheel-Rear Wheel 45 mm Wheels

With lighter 45 mm rims featuring UD2 finish, this carbon wheelset is the fastest, stiffest and lightest all-rounder for road bikes with disc brakes.

• This carbon wheelset is a great choice for road riders aiming to be fast and efficient in all types of riding and racing situations. Not only does the 45 mm airfoil rim slice through the wind with minimal drag, but it’s also amongst the lightest in its category. This season, the external carbon layer features UD2 construction for a distinctive look and an even lighter rim laminate, saving another 15 g per rims.
• A rim laminate coupled with exclusive Fore Carbon technology leaves the upper rim bridge intact and reinforces the rim only where needed, saving 40 g 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 (30 g) and less hassle when it comes to set up or repair tubeless tyres. The 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, patented elliptical spokes save another 5 watts.
• 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.

• UD2 rim laminate and Fore Carbon spoke attachment save 55 g and eliminate rim tape (another 30 g saved per wheel)
