Trusted Mavic technologies and design, all packaged in a lightweight, durable wheelset with a stunning finish make this a smart upgrade for any road rider.This lightweight aluminum wheelset is a no brainer for anybody looking to make an easy upgrade from OEM wheels. The Ksyrium S can significantly boost any bike’s performance and is an easy entry point to Mavic quality that doesn’t take any shortcuts.The Ksyrium S is 60 g lighter than the former Ksyrium UST while also being wider, stronger and laterally stiffer. Stiffness is optimized using Fore technology. The upper bridge remains undrilled, optimizing strength and rigidity, and it doesn’t require the use of a rim tape, which saves another 30 g per wheel. 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. Those rims are made in France, in aluminum rim factory.Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while an Instant Drive 360 freewheel coupled with automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. The Ksyrium S doesn’t just ride fast, it looks fast too. Matte painted hubs, invisible rim welding and deep black spokes give this wheelset a premium look that stands out from the crowd.KEY BENEFITSLightweight and durable for everyday performanceRim weighs only 430 gNo rim tape is needed, saving 60 g over a traditional wheelFlat, lightweight spokes and ID360 freewheel technologyLaterally stiff and vertically compliant for a more dynamic rideFore technology keeps the rim upper bridge solid to make the 19 mm wide rim stifferInfinity hub plaform: stiff axle, durable bearings and hub designImproved UST Road delivers more speed, comfort and control in an easy to use tubeless systemNo tubes means less friction, better efficiency and grip, a reduced risk of puncturesRim bed shape makes it easier to mount and change tiresFore drilling technology doesn’t require the use of rim tapeAxle Standard: 9x100Axle Standard: 9x135Brake Type: Rim BrakeCassette Mount: Shimano HGColour: BlackMade in: RomaniaMaterial: AluminiumUsage Bikesport: RoadWheel Diameter: 29/28’’ (622 mm)Type of Product: Pair of WheelsWeight (g): 1570.0Number of Spokes: 20Number of Spokes: 24Inner Rim Width: 19.0
