In addition to the superlight, 100% tubeless 32mm carbon rim, Cosmic SLR gets ceramic bearings. The perfect mountain roads wheelset.Features:Adaptive Layup Carbon technology:- Strong where it matters, light everywhere else.Infinity hub design:- Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.UST tubeless technology:- Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.Instant Drive 360 freewheel technology:- The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.Fore technology:- Stiffer and stronger. Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.Aero Wide Rim Technology:- Unmatched speed, control, and comfort combo.Mavic Ceramic Premium bearings materials, premium performance:- With its special properties, ceramic makes bearings spin a little faster and are more durable. Together with premium ceramic material, we use premium low-density grease paired with ultra slick seals.Adaptive Layup Strong where it matters, light everywhere else:- Carbon is lighter than alloy, but weight always add up. Using the right amount of fibers where the rim is less stressed to reduce rim weight with no compromise on reliability, this gives wheels that are livelier and more enjoyable while climbing. Up to 70g saved per rim.FORE Stiffer, high precision and durable rim/spokes link with convenient Tubeless benefits:- The lower bridge of the rim is threaded to receive the spokes directly at the appropriate angle. This gives a stiff link, no spoke movement (less spoke break), and the rim upper bridge remains undrilled so 100% airtight for easy Tubeless set up.Specifications:Rims:- Tire: UST Tubeless Ready- Braking: Disc- Drilling: Fore Carbon tapeless tubeless technology (rear 24 holes)- Material: 100% Unidirectional carbon fiber- Internal width: 21 mm- ETRTO size: 622x23TC- Height: 32 mm- Weight Rear: 760 gramsSpokes:- Lacing: Crossed 2 (rear) - Screw: M6- Shape: Straight, aero, constricted, antirot (rear)Hubs:- Axle material: Aluminum- Body material: Aluminium- Freewheel: Shimano HG road / Sram XD road- Disc standard: Center Lock® only- Axle size: Rear 12x142- Bearings: Mavic CeramicIntended use:- ASTM category 2: Road and offroad with jumps less than 15cm- Maximum weight supported by the wheels: Must not exceed 120 kg (bike weight included)- Maximum tyre size: Width 64mm pressure max. 3.25Bar/51PSI- Minimum tyre size: Width 25 pressure max. 6.1Bar/88PSICompatibility:- Freewheel body: Convertible Shimano HG light road - Freewheel body: Convertible Campagnolo N3W - Freewheel body: Convertible SRAM XD roadIn the box:- User guide- Rim tape mounted on wheel
