Ksyrium has always represented the best of aluminum wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Ksyrium SL Disc lives up to that standard. If you're looking for one aluminum wheelset for weekend races and training mileage, wherever the road takes you, this is your best choice.
This new wheel is superlight (120g lighter than the former Ksyrium Elite UST Disc) and durable as ever thanks to our patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest. Those rims are made in France, in our aluminum rim factory.
The double-butted spokes contribute to the weight reduction while making the wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency.
Stiffness is optimized using Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of a rim tape (another 30g saved 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. 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. Engineered specifically for disc brakes, the wheels are compatible with a 12x100 axle up front, and 12x142 rear and can convert to Quick Release with supplied adapters. For Center Lock disc rotors only. It's available for Shimano or Sram XD-Road cassettes and can convert to Campagnolo with an optional driver body.
