The stealth outlook and superior braking performance of Exalith, now available with a wider and light ISM4D rim.
Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST gives you all the advantages of their 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 their 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.
UST Tubeless Ready - Traction, control and lightweight. The UST concept improves traction, control and comfort while reducing inertia and flats. The 'tubeless ready' construction results in a lighter tyre for improved performance.
Maxtal - Light and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than conventional 6106 alloy.
UB Control - Usine Brut Control. The braking surfaces are precisely CNC machined.
Instant Drive 360 - The new Instant Drive 360 freewheel system is super light and fast to engage with only 9 degrees. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Zicral - Light, stiff and strong. A specific aluminium alloy that provides spokes with high stifness-to-weight ratio while being stronger.
SUP - Soude Usine Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
ISM 4D - Inter Spoke Milling 4 Dimensions. An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag.
Isopulse - The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.
