Mavic Ksyrium 29/28" (622 mm) Rim Brake 9x100-9x135 Shimano HG Pair of Wheels Wheels #44397

Lightweight and very durable, laterally stiff but vertically compliant. The Ksyrium SL raises the bar, setting a standard for aluminum road wheels. Ksyrium has always represented the best of aluminum wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the 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 wheel is lightweight (100 g lighter than the former Ksyrium Elite despite its wider rim) and durable as ever thanks to 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 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 30 g saved per rim). The rim bed’s shape makes it easier than ever to mount and remove tires, and UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while the Instant Drive 360 freewheel coupled with 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.   KEY BENEFITS Superlight and durable for everyday performance ISM4D rim weighs only 400 g Patented lightweight aero spokes and 22 mm deep/19 mm wide rims keep inertia low and control high Solid upper rim bridge eliminates the need for rim tape, saves 60 g   Laterally stiff, vertically compliant for a more dynamic ride Fore technology keeps the rim upper bridge solid to make the rim stiffer Infinity hub plaform: stiff axle, durable bearings and 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 Rim bed shape makes it easier to mount and change tires Fore drilling technology doesn't require the use of rim tape Weight (g): 1480.0 Type of Product: Pair of Wheels Wheel Diameter: 29/28' (622 mm) Number of Spokes: 20;24 Usage Bikesport: Road Cassette Mount: Shimano HG Inner Rim Width: 19.0 Axle Standard: 9x100;9x135 Material: Aluminium Brake Type: Rim Brake Colour: Black Made in: Romania
