Mavic Ksyrium S Disc Road Disc Wheelset Description: The Mavic Ksyrium S Disc Road Disc Wheelset makes a more than worthy upgrade for OEM-equipped road wheels; lightweight and considerate engineering leaves Ksyrium S Disc wheels a significant boost to the performance of any road bike. Clocking in at 40g lighter than Ksyrium UST Disc wheels, Ksyrium S rims manage to display higher strength and lateral stiffness, a result of the implementation of Fore technology. Fore technology dictates that the upper bridge remains undrilled, optimizing strength and rigidity and eliminating the need for rim strips, a measure that saves 30g per wheel. This special rim bed design also eases the process of installing and removing tires, while UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Infinity hubs elevate 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.
