Not only does the 40mm airfoil rim slice through the wind with minimal drag, but it's also the lightest in its category. 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 and less hassle when it comes to set up or repairing tubeless tyres. The shape of the rim bed also makes it easier than ever to mount and remove tyres. 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, our patented elliptical spokes save another 5 watts. Mavic's Infinity hub platform optimises 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. In addition to more speed, you also get better braking control with Mavic's proven iTgMax technology. A patented laser treatment of the brake track shortens stopping distance in both dry and wet conditions, and a special lay-up and heat treatment process makes it the strongest and most durable of all carbon rims for rim brakes. These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in their European carbon factory. **Technologies** **Fore Carbon tapeless tubeless technology** Stiffer and stronger. A fully sealed upper rim bridge eliminates the need for rim tape. The spokes are directly screwed in the insert. A threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge. **Instant Drive 360 technology** Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile. **Isopulse lacing design** Optimum energy transfer. The spokes are laced radially on the drive side **UST tubeless technology** Traction and control. The UST concept improves traction, control and comfort whilst reducing inertia and flats **iTgMAX Carbon Clincher technology** Integral Glass Transition Temperature. The inner rim bed is finished with multiple layers of seamless carbon fibre to achieve a unique one-piece rim contour without cutting any fibres. The brake track is then finished with laser machining to ensure the best braking efficiency. **Infinity Hub Design** An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear. **QRM Auto bearing preload technology** Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run. **Technical Specifications:** * Profile depth: 40mm * Inner width: 19mm * Front axle: 9x100mm Quick Release * Rear axle: 9x130mm Quick Release * Discipline: Road * Spokes: Steel, Straight, aero * Rim Diameter: 700c * Nipples: Brass Black * Rim material: 100% carbon fibre * Tyre compatibility: UST Tubeless Ready * Maximum weight: 120kg including bike * Bearings: QRM automatic setting - sealed cartridge * ETRTO Size: 622x19TC * Weight: 1390g **What's in the box?** * Wheelset * User guide * Quick release level 2 * x2 Carbon brake pads * UST valve not mounted on the wheel * Multifunction adjustment wrench * Spoke M6 wrench with rear wheel **Intended Use** * Minimum tyre size: width 23mm - pressure max. 6.75Bar/97PSI * Maximum tyre size: width 62mm - pressure max. 3.8Bar/55PSI * ASTM category 1: road only
