MAVIC Ksyrium SL Tubeless road rear wheel 9/12 x 135/142 mm

Ksyrium has always represented the best of aluminum wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Ksyrium SL takes it to the next level. It’s the perfect all-rounder for those seeking a wheel that delivers reliable everyday performance on the road. This new wheel is lightweight (100g lighter than the former Ksyrium Elite despite its wider rim) and durable as ever thanks to our patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest. Those rims are made in France, in our aluminum rim factory. The double-butted spokes further reduce weight while making the wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency. Stiffness is optimized using Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of a rim tape (another 30g saved per rim). The rim bed’s new shape makes it easier than ever to mount and remove tires, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Our new Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while the Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. It´s available for Shimano cassettes, and can convert to Campagnolo or SRAM XD-Road with optional driver bodies. Features: Superlight and durable for everyday performance: - ISM4D rim weighs only 400g - Patented lightweight aero spokes and 22mm deep/19mm wide rims keep inertia low and control high - Solid upper rim bridge eliminates the need for rim tape, saves 60g Laterally stiff, vertically compliant for a more dynamic ride: - Fore technology keeps the rim upper bridge solid to make the rim stiffer - New Infinity hub plaform: stiff axle, durable bearings and new hub design guarantees wheel stability - ID360 freewheel technology for improved power transfer Improved UST Road delivers more speed, comfort and control in an easy to use tubeless system: - No tubes means less friction, better efficiency and grip, a reduced risk of punctures - New rim bed shape makes it easier to mount and change tires - Fore drilling technology doesn´t require the use of rim tape Specifications: Compatibility - Rear axle: Quick Release only - Freewheel: Shimano/Sram, convertible to Campagnolo and XD-R with optional driver bodies Compatible Adapters and freewheel bodies: - ID360 Shimano / Sram freewheel body (LV3430100 - Delivered on the wheel) - ID360 XD-R freewheel body (LV2580100) - ID360 Campagnolo freewheel body (LV3440100) - ID360 Shimano / Sram Light freewheel body (LV3850100) Hubs: - Infinity Hubs - QRM Auto bearing preload technology - Instant Drive 360 freewheel technology - Axle material: aluminum Rims: - Height: 22 mm - ETRTO size: 622x19TC Road - Weight reduction: ISM 4D - UST tubeless technology - Fore tapeless tubeless technology - SUP welding technology - Internal width: 19 mm - Tire: UST Tubeless and tubetype - Brake track: UB Control - Material: Maxtal Intended Use: - Max. Pressure: see indication on wheel and tyre. If they differ, use the lowest of the 2 - For a longer longevity of the wheel, Mavic recommends that the total weight supported by the wheels doesnn´t exceed 120kg, bike included - ASTM CATEGORY 2 : road and offroad with jumps less than 15cm - Recommended tyre sizes: 25 to 32 mm Versions: - Freewheel: Shimano/Sram or XD-Road - Disc standard: Center Lock (R) only Weight: - Rear without tyre: 835 grams Spokes: - Shape: straight pull, elliptical aero, double butted (patented) - Isopulse lacing design - Material: steel - Nipples: Fore integrated aluminum - Lacing: front radial, rear Isopulse - Count: 24 front and rear Technology: ISM 4D light rim technology: - Inter Spoke Milling 4 Dimensions An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance ; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag QRM Auto bearing preload technology: - Qualité de Roulements Mavic Auto Our latest innovation. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run. 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. Maxtal aluminum alloy: - Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy. SUP welding technology: - Stronger and smoother joint Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. Fore tapeless tubeless 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. Isopulse lacing design: - Optimum energy transfer The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges. Instant Drive 360 freewheel technology: - Instant Drive 360 freewheel technology The new Instant Drive 360 freewheel system is super light and fast to engage with only 9°. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
