Mavic's Ksyrium SL discs represent the pinnacle of aluminium wheel technology. These wheels offer a combination of lightness, high lateral stability, and flexibility for dynamic riding. Equipped with Fore technology for maximum tubeless performance and high-quality Infinity hubs, they deliver an exceptional ride experience. The SM4D rim weighs only 400g and features patented lightweight aero spokes and 22mm deep/19mm wide rims to minimize inertia and maximize control. Fore technology eliminates the need for rim tape, saving 30g per wheel, and keeps the rim upper bridge solid for increased stiffness. The new Infinity hub platform ensures wheel stability with a stiff axle and durable bearings, complemented by ID360 freewheel technology for improved power transfer. The improved UST Road system enhances speed, comfort, and control in an easy-to-use tubeless setup. Running tubeless means less friction, better efficiency, improved grip, and a reduced risk of punctures. The new rim bed shape simplifies tire mounting and removal. Engineered specifically for disc brakes, these wheels are compatible with 12x100 front and 12x142 rear axles and can be converted to Quick Release. They are designed for Center Lock disc rotors only and are available for Shimano or Sram XD-Road cassettes, with optional Campagnolo driver bodies.
