Mavic Ksyrium SL Heritage Road Disc Wheelet The Ksyrium SL Heritage Disc Wheelset represents the pinnacle of aluminum wheel technology, blending a featherweight build with elite-level durability. At the heart of this wheelset is the ISM4D rim, weighing just 400g and featuring a solid upper bridge that eliminates the need for rim tape, saving weight and simplifying tubeless setups. This design results in incredibly low inertia for snappy acceleration, while the 22mm deep profile and aero spokes ensure you maintain speed with minimal effort. It is the definitive all-rounder for cyclists who demand a wheel that is laterally stiff for explosive sprints yet vertically compliant for all-day comfort. Precision Engineering for Every Road Every component of the Ksyrium SL is meticulously crafted to enhance your riding dynamics and mechanical reliability. The Infinity hub platform provides a stable axle and ultra-durable bearings, paired with ID360 freewheel technology for near-instant power transfer when you step on the pedals. Thanks to the improved UST Road system and Fore drilling, mounting tubeless tires is easier than ever, offering you increased grip and a significantly reduced risk of punctures. With a total weight of 1575g and compatibility across Shimano HG, SRAM XD-R, and Campagnolo platforms, this wheelset delivers a premium, high-performance experience for those who refuse to compromise on their daily rides.
