Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST gives you all the advantages of Mavic's Road Tubeless system including less rolling resistance and a smoother ride quality. When paired with the new Yksion Pro UST tubeless tires, you get a perfect union between the wheel and tire, ensuring easy, hassle-free installation and removal thanks to Mavic's proven UST technology. And no tubes means no friction with the tire, so you roll faster using less energy. You can also lower your tire pressure for a smoother, more compliant ride, even on rough roads, with a reduced risk of punctures. Beyond the benefits of tubeless, all the other favorite features of this wheel stay the same. A wider rim shape (17mm internally) allows for an 18% increase in air volume for your tires. That extra volume gives you a more controlled and comfortable ride without compromising efficiency. The Zicral alloy spokes 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%. 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. Total wheel weight is about 1420g.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
