Product Description
The Ksyrium has always represented the best of aluminium wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Ksyrium SL Disc lives up to this standard. If you're looking for a pair of aluminium wheels for weekend races and training miles, wherever the road takes you, this is your best choice.
This new wheel is super light (120 g less than the old Ksyrium Elite UST Disc) and more durable than ever thanks to our patented ISM4D technology. This manufacturing process removes excess material between each spoke hole while keeping the rim wall thick enough where tension and stress from the spokes are highest. These rims are made in France, in our aluminium rim factory. The double-butted spokes help reduce weight while making the wheel more responsive. These spokes also have a patented elliptical shape that saves 5 watts for improved efficiency.
Stiffness is optimised thanks to Fore technology. The upper bridge is not drilled, remaining solid and rigid, eliminating the need for rim tape (an additional saving of 30 g per wheel). The new rim bed shape makes mounting and removing tyres easier than ever, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Our new Infinity hub platform optimises stiffness and power transfer with highly controlled spoke tension, while an Instant Drive 360 freewheel combined with our automatic bearing preload adjustment (QRM Auto) offers quick engagement and great longevity. Specifically designed for disc brakes, the wheels are compatible with a 12x100 axle at the front and 12x142 at the back and can be converted to Quick Release with adapters. For Center Lock discs only. They are available for Shimano or Sram XD-Road cassettes and can be converted for Campagnolo with an optional freehub body.
Main Features
Super light and durable for everyday performance
The ISM4D rim weighs only 400 g
The patented light spokes and rims with a depth of 22 mm and a width of 19 mm reduce inertia and increase control.
The solid upper bridge of the rim eliminates the need for rim tape, allowing a saving of 60 g.
Lateral stiffness, vertical compliance for a more dynamic ride
The Fore technology keeps the upper bridge of the rim solid for more rigidity.
New Infinity hub shape: stiff axle, durable bearings, and a new hub design ensuring wheel stability
ID360 freewheel technology for better power transfer
The improved UST Road offers more speed, comfort, and control in an easy-to-use tubeless system.
The absence of an inner tube reduces friction, improves efficiency and grip, and decreases the risk of punctures.
The new rim bed shape makes tyre fitting and changing easier.
The Fore drilling technology does not require rim tape.
