For World Cup racing and fast trail riding The most responsive UST wheel-system for fast accelerations Convenience and reliability of a Mavic UST system The lowest inertia: new ISM 4D rim. Stiff: 19 mm rim Thru-axle compatible

Material: Maxtal Joint: SUP Drilling: Fore Disc brake: specific profile Weight reduction: ISM 4D Valve hole diameter: 6.5 mm Tire: UST Tubeless and tube type Internal width: 19 mm ETRTO size 29": 622x19C Recommended tire sizes: 1.5 to 2.3 SPOKES Material: Zicral Shape: straight pull, bladed Nipples: Fore integrated aluminum Count: 20 front and rear Lacing: front crossed 2, rear Isopulse HUBS Front body: carbon with aluminum flanges Rear body: aluminum Axle material: aluminum Bearings: Adjustable sealed cartridge bearings Freewheel: ITS-4 alloy Freewheel Body: M11 (Shimano & SRAM 8/9/10/11-speed), XD Compatible (XX1-X01) with optional kit (Not included!) ISM 4D Inter Spoke Milling 4 Dimensions An exclusive Mavic patented concept, ISM 4D not only significantly reduces weight and reduces inertia without compromising durability, but also improves aerodynamics due to its new rim shape. Up to 50 grams lighter for faster climbing The lowest inertia for instant acceleration A smooth aerodynamic rim shape to reduce drag UST 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. No tube, no tape, fully sealed rim for convenient handling Enables to ride at lower tire pressure UST rim profile with specific humps to fix securely the tire beads Compatible with all types of tires (UST, Tubeless ready, tube type) ITS-4 Instant energy transmission Instant Transfer System 4: Using 4 pawls working 2 by 2, the system provides a more dynamic ride, thanks to a very fast engagement. Its versatility makes it compatible with all kinds of frame retention system. Better energy transmission: fast engagement, only 7.5° freeplay between two engaged positions Stiffer: 17 mm monobloc axle 12 mm through axle compatible to fit any kind of frame retention system Fore 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. Rim is 4 times more resistant to fatigue stress 20% increase in the rim rigidity to maximize power transfer
