Aerodynamic efficiency, quick acceleration and the improved ride quality of UST Tubeless. You have it all with this easier to use and lighter carbon road wheel with Road Tubeless technology.Pair Weight: 1600gFront Weight: 705gRear Weight: 895gThis versatile carbon road wheel is ideal for cyclists looking for 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 designed with a 40mm high and 26mm wide NACA rim profile, specifically designed for all-purpose performance on flat or rough terrain. The new rim base shape makes it easier than ever to mount tubeless and tubeless tires. Riding UST Tubeless means there´s no tube, so no friction, and more air volume means a smoother ride. The result is a faster ride with very low rolling resistance.Refined spokes make these wheels 80g lighter than their predecessor, the Cosmic Pro Carbon UST. Combined with our new Infinity hub platform, which makes them fast and responsive through every corner, they are stiffer and more efficient.The Cosmic SL 40 is designed specifically for rim brakes. Our proven iTgMax technology includes a patented laser treatment of the braking track that shortens braking distance in both dry and wet conditions, while a special lamination and heat treatment process makes it the strongest and most durable carbon rim for braking. of tire. They are available for Shimano cassettes, and convert to Campagnolo and SRAM XD-R with optional hubs.These wheels have been designed, engineered and patented by Mavic in Annecy, France, and are 100% hand-made in our European carbon factory.Accelerate and climb faster, maintain higher speedsThe NACA-inspired 40mm rim shape minimizes drag for increased speed.The reduced inertia of the lightweight tire provides instant acceleration.Flat double-butted spokes save weight and improve responsivenessVersatile performance for all road driving conditionsIts minimum resistance, low inertia and high lateral rigidity make it fast and efficient on all types of terrain, from flat to mountain climbs.iTgMAX braking track offers the best braking efficiency and reliability of any carbon rimImproved UST Road offers more speed, comfort and control in an easy-to-use tubeless systemTubeless means less friction, better efficiency and grip, lower risk of puncturesNew rim base shape makes mounting and changing tires easierTiresMaterial: 100% carbon fiberHeight: 40mmInner width: 19mmPerforation: traditional (18 holes in front and 24 holes in back)Braking: brake padsETRTO size: 622x19TCTire: UST Tubeless Ready - Use with Mavic tubeless rim tapeRadiosMaterial: steelShape: straight, flat, constricted (front and rear on the opposite side to the freewheel)Shape: straight, flat, anti-rotating (rear freewheel side)Spikes: steel, ABS, blackLacing: Radial (front) - Isopulse (rear)BushingsBody material: aluminumBody Design: INFINITYShaft material: aluminumAxle size: front 9x100 / rear 9x130 - Quick release onlyFreewheel technology: Instant Drive 360Freewheel: Shimano HG roadBearing technology: Self-adjusting QRM - sealed cartridgeCompatibilityFreewheel body: SRAM XD road convertible (kit V2580101 sold separately)Freewheel body: SHIMANO HG lightweight road convertible (kit V3850101 sold separately)Freewheel body: SHIMANO MS convertible (kit V3990101 sold separately)Freewheel body: CAMPAGNOLO ED convertible (kit V3440101 sold separately)Delivered withUser GuideQuick closing level 2Carbon brake pads with each wheelUST rim tape mounted on the wheelUST valve not mounted on the wheelMultifunction adjustment wrench with rear wheelIntended useMinimum tire size: width 23 mm - max. pressure 6.75 Bar/97 PSIMaximum tire size: width 62 mm - max. pressure 3.8 bar/55 psiASTM category 1: road onlyMaximum weight supported by the wheels: must not exceed 120 kg (including the weight of the bicycle)
