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.

The Cosmic name represents that perfect balance between aerodynamics and weight. It’s about producing more speed on the flats while minimizing weight for the climbs. This all-new Cosmic Elite takes those qualities to the next level with Mavic's UST Tubeless Road Technology. Removing the tube reduces friction and allows you to run lower tire pressures with less worries about punctures. That makes it both faster and smoother, even on rough roads. It’s also engineered specifically for disc brakes, with steel-bladed straight-pull spokes that are stronger than traditional J-bend spokes, which are connected to Mavic's strongest hub platform running on smooth QRM bearings. Mavic's extensive wind tunnel testing led us to create a 30mm deep rim that optimizes aero performance and improves stability in crosswinds. The thickness of the rim wall is carefully tuned to hit the sweet spot between stiffness, strength and weight. Pedaling torque is efficiently transferred with Mavic's FTS-L freewheel system—light, smooth, stiff and easy to service. This hub easily converts from Shimano/SRAM to Campagnolo cassette. The Cosmic Elite Disc comes with Mavic's Yksion Pro UST tires, which deliver a very low rolling resistance to further enhance the efficiency of these wheels.

The Cosmic Elite is a perfect entry point into high-level race performance. This UST Road Tubeless system delivers a smoother ride and improved puncture resistance while retaining a lightweight feel for climbing and accelerating.
