Mavic Cosmic SLR 45 Disc 28" front wheel, 12 x 100 mm
This all-new carbon wheelset is a great choice for road riders who want to be fast and efficient in all types of riding and racing situations. Not only does the 45mm wing profile cut through the wind with minimal drag, it is also among the lightest in its category. This season, the outer carbon layer features our new UD² construction for a distinctive look and an even lighter rim laminate, saving an additional 15g per rim. The new rim laminate combined with our exclusive Fore Carbon technology leaves the upper bridge of the rim intact and reinforces the rim only where it is needed, saving 40g per rim. The spokes attach to the rim without the need for drilling into the upper rim seat, so there is no need for rim tape. This means greater weight savings (30g) and fewer problems when adjusting or repairing tubeless tires. The new rim bed shape makes mounting and dismounting tires easier than ever. The 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. Finally, our patented elliptical spokes save an additional 5 watts. Our new Infinity hub platform optimizes 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 increased durability. It is compatible with 12x100 axle. 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.
