This versatile carbon road wheel is ideal for riders seeking the perfect balance between weight, aerodynamics and efficiency. New spokes and hubs give the Cosmic SL 40 a light and lively feel for climbing and accelerating.The rim is engineered with a NACA rim profile that’s 40mm deep and 26mm wide, designed specifically for all-rounder performance on flat or hilly terrain. The new rim bed shape makes it easier than ever to fit tubeless and tube-type tires. 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. Combined with our all-new Infinity hub platform, which makes them feel quick and responsive out of every corner, they are stiffer and more efficient.The Cosmic SL 40 is engineered specifically for rim brakes. Our proven iTgMax technology features a patented laser treatment of the brake track that shortens stopping distance in both dry and wet conditions, while a special lay-up and heat treatment process makes it the strongest and most durable of all carbon rims for rim brakes. They are available for Shimano cassettes, and convert to Campagnolo and SRAM XD-R with optional driver bodies.These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.Accelerate and climb faster, hold higher speeds40mm NACA inspired rim shape minimizes drag for added speed.Reduced inertia of the lightweight rim delivers instant acceleration.Flat double butted spokes saves weight and improves responsivenessVersatile performance for all road riding conditionsMinimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types of terrain, from the flats to mountain climbsiTgMAX brake track offers the best braking efficiency and highest reliability of all carbon rimsImproved UST Road delivers more speed, comfort and control in an easy to use tubeless systemNo tubes means less friction, better efficiency and grip, a reduced risk of puncturesNew rim bed shape makes it easier to mount and change tires
The Cosmic name has always been synonymous with speed and performance. This 65mm version for disc brakes is no exception, and it’s the fastest of the family when it comes to hammering the flats and in the wind.The 65mm deep airfoil rim slices through the wind with minimal drag, and its 26mm wide profile makes it highly stable in crosswind. It also uses our patented elliptical spokes that save another 5 watts to maximize your efficiency.Another key factor in efficiency is rolling resistance, which we address with our updated UST Road Tubeless system that makes it easier than ever to mount and change tires. No tube means no friction, and more air volume means a smoother, faster ride. Exclusive Fore Carbon technology attaches the spokes to the rim without the need to drill the upper rim bed. With the new rim bed shape, no tape is needed, eliminating any hassles and saving 30g per rim.We further lowered the weight of the rim with a new laminate and local reinforcement.Our new Infinity hub platform optimizes spoke lacing and tension for maximum power transfer.The Instant Drive 360 freewheel, coupled with automatic bearing preload (QRM Auto), provides fast engagement, high stiffness and added durability. It's available with Shimano or SRAM XD-Road driver bodies and converts to Campagnolo with an optional driver body. It's compatible with 12x100 axle up front, and 12x142 rear, and can convert to Quick Release with supplied adapters. For Center Lock disc rotors only.KEY BENEFITSUnbeatable aero efficiency and added stability in crosswinds65mm deep/26mm wide NACA rim profile produces super low drag and stability in cross windsPatented lightweight aero spokesFaster acceleration and powerful braking performanceNew Infinity hub plaform: stiff axle, durable bearings and new hub design with ID360 freewheel technologyNew rim design eliminates need for tape, saving 30gPurpose-built for disc brakesImproved UST Road delivers more speed, comfort and control in an easy to use tubeless systemNo tubes means less friction, better efficiency and grip, and a reduced risk of puncturesNew rim bed shape makes it easier to mount and change tiresFore Carbon drilling technology doesn't require the use of rim tape
