Ksyrium has always represented the best in aluminum wheel technology. In the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Ksyrium SL moves up a gear. It's the ideal all-around wheel for riders looking for reliable support for everyday performance on the road.
This new wheel is light (100g less than the old Ksyrium Elite, despite a wider rim width) and still just as durable thanks to our patented ISM 4D process. This machining process makes it possible to remove all the excess material between each spoke hole, while maintaining sufficient wall thickness where spoke tension and stresses are greatest. These rims are made in France, in our aluminum rim factory.
Butted spokes further reduce weight and make for an even more responsive wheel. Their patented elliptical shape also saves energy to increase efficiency.
Fore technology reinforces rigidity. The upper bridge of the rim is not drilled; it therefore remains resistant and rigid, and does not require the installation of a rim tape (another 30 g less per rim). With the new profile of the upper bridge of the rim, mounting and demounting a tire has never been so easy; our UST Tubeless technology reduces rolling resistance and increases grip while limiting the risk of punctures. Our new Infinity hub platform optimizes stiffness and power transfer, thanks to carefully tuned spoke tension. The Instant Drive 360 freewheel body, combined with the automatic adjustment of the QRM Auto bearings, guarantees quick engagement, good rigidity and increased durability.
It can be fitted with Shimano cassettes, and is convertible to Campagnolo or SRAM XD-Road using optional freewheel bodies.
