Mavic Ksyrium S (pr)

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 60g 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 30g per wheel. 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. Those 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 an Instant Drive 360 freewheel coupled with our 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.

It's available for Shimano cassettes, and can convert to Campagnolo or XD-Road with optional driver bodies.
