Ksyrium Pro UST

The legacy of the Ksyrium family gets through a major step up: the lightest road tubeless alloy wheelset


Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST delivers comfort and performance for a variety of riding conditions. Key updates include a UST tubeless compatible rim. When combined with our new 25mm Yksion Pro UST tubeless tires, the result is an 15% increase in rolling efficiency at equal tyre pressure. Or 5% rolling resistance improvement with 1bar /15PSI lower pressure to get extra comfort and grip. Other major updates include redesigned lighter hub shells, the implementation of our fast engagement Instant Drive 360 hub and new automatic adjustment of the bearing preload for long terms smoothness with no lay. Still laced with our proprietary Zicral alloy spokes that are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel. Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20%, and makes tubeless super easy to use, without the need for a rim tape. Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400g. All in all, the total wheel weight is down to an impressive 1420g.
