With the lowest rolling resistance of any wheel in its category, this high-performance carbon all-rounder features our all-new UST Road Tubeless technology. It’s designed for competitive riders seeking the most advanced, high-performance wheel and tire technology for speed, puncture resistance and smooth-riding comfort on the road. Not only does it out-perform other wheels with its low rolling resistance, deliver a smoother ride, and reduce your risk of punctures, but it’s also the most user-friendly tubeless system when it comes to installation, removal and maintenance. As a pioneer in tubeless technology with our proven UST system, Mavic provides the confidence that comes with our history and expertise. The rim design of the Cosmic Pro Carbon SL UST Disc features a 19mm inner width that’s ideal for 25mm tires. The aerodynamic NACA profile reduces wind drag and improves crosswind stability. This model is built specifically for disc brakes, with 24 spokes front and rear to evenly distribute brake torque. The front spokes are also crossed on each side of the hub to transfer the braking load to the ground with no loss of stiffness and no wheel wobbling. The rear wheel has Isopulse lacing (radial on the drive side) for maximum power transfer. It’s built on the Instant Drive 360 hub, which offers fast freewheel engagement and compatibility with any kind of frame. It’s delivered with 12x142 and converts to quick release. The system comes with Yksion Pro UST tires that provide a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather. The Cosmic Pro Carbon SL UST Disc works with 6-Bolt and Center Lock rotors and Shimano or SRAM cassettes. It’s convertible to Campagnolo or SRAM XD with optional driver bodies.

UST Tubeless Ready

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.

Instant Drive 360

Instant Drive 360

The new Instant Drive 360 freewheel system is super light and fast to engage with only 9°. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.

Isopulse

Isopulse

Optimum energy transfer
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.
