Cosmic Ultimate UST Carbon Wheel

What Our Gearhead® Experts Are Saying:

"I’ve ridden a lot of top-end wheels, but nothing compares to the feel of the Cosmic Ultimate 45. The acceleration is instantaneous, the stiffness unreal, and the carbon spokes give it that razor-sharp response without harshness. They’re featherlight yet feel bombproof, and the tubeless setup is completely hassle-free. It’s the kind of wheelset that makes every ride feel like a race."

The Mavic Cosmic Ultimate 45 Disc front and rear wheels represent the peak of modern carbon engineering—a handmade masterpiece designed for pure speed and control. Weighing only 1255 grams for the pair, they bring together aerodynamic efficiency, exceptional stiffness, and ultralight precision for riders chasing podiums and personal bests. The 45mm deep, 27mm wide NACA-inspired carbon rim profile slices through wind while maintaining predictable stability across changing conditions. Built entirely in Mavic’s carbon workshop in Annecy, France, these wheels are shaped by the same meticulous craftsmanship that defines the brand’s racing legacy.

Each wheel is constructed using a monobloc carbon design with continuous, unidirectional carbon spokes that run rim-to-rim through the hub using Mavic’s R2R lacing system. This eliminates mechanical spoke junctions, delivering unrivaled stiffness and immediate power transfer. The result is a seamless structure that’s both lighter and stronger than traditional builds. The tapeless UST tubeless-ready rims simplify setup and improve rolling resistance, while the QRM sealed cartridge bearings and Instant Drive 360 freehub maximize efficiency and engagement under load.
