This lightweight aluminum wheelset is a no-brainer for anyone looking to make an easy upgrade from OEM wheels. The Ksyrium S Disc can dramatically improve the performance of any bike and is an easy entry point to Mavic quality that takes no shortcuts. The Ksyrium S Disc is 40g lighter than the previous Ksyrium UST Disc while being stronger and stiffer laterally. Rigidity is optimized thanks to Fore technology. The upper deck remains undrilled, optimizing strength and stiffness, and it does not require the use of rim tape, saving an additional 30g per wheel. The new shape of the rim tape makes mounting and demounting tires easier than ever, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. These rims are made in France, in our aluminum rim factory. Our new Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while our Instant Drive 360 ​​freewheel paired with our Automatic Bearing Preload Adjustment (QRM Auto) provides a rapid engagement and sustainability. The Ksyrium S Disc doesn't just ride fast, it looks fast too. Matte painted hubs, invisible rim welds and deep black spokes give this wheelset a premium look that stands out from the crowd. Designed specifically for disc brakes, it is compatible with a 12x100 front and 12x142 rear axle, and can be converted to Quick Release with the supplied adapters. It is available for Shimano and Sram XD-Road cassettes and can be converted to Campagnolo with an optional rider body. Only for Center Lock disc rotors.
