Description

The MAVIC COSMIC ULTIMATE 45 rear wheel lives up to its name: "Ultimate" is synonymous with absolute excellence. Developed to deliver the very best in performance, it combines extreme lightness, stiffness and aerodynamics in a package weighing just 1,260 g. Compatible with tubeless and clincher tyres as well as disc brakes, it is aimed at the most demanding cyclists in pursuit of speed, reliability and unique sensations.

Its carbon rim, featuring a 45 mm NACA profile and an external width of 32 mm, combines aerodynamic efficiency and stability. Thanks to a complex layup, the weight-to-stiffness ratio is optimised, while the Adaptive Lay Up layer stacking allows a weight saving of 70 g. Unpierced, the rim requires no rim tape for airtightness, ensuring simple and hassle-free tubeless use.

The UST Tubeless system and the 23 mm internal width simplify the installation of wide tubeless tyres from 700x28, offering greater comfort and manoeuvrability while reducing friction and the risk of punctures.

On the spoke side, R2R (rim-to-rim) technology makes the difference. The 20 elliptical spokes made from unidirectional carbon fibres are continuous, passing through the hubs to form a one-piece structure. This design considerably increases stiffness, improves aerodynamics and eliminates the weak points associated with traditional fixings.

The carbon hub integrates ceramic bearings for smooth and durable operation delivering Premium performance. At the rear, the ID360 freehub system ensures instant engagement with its 40 points, for explosive accelerations and lossless power transfer. Designed for 12x142 mm thru-axles and Center Lock disc brakes, this wheel is perfectly suited to modern bikes.

Entirely handmade in France at Mavic's carbon workshop in Annecy, the Cosmic Ultimate 45 Disc wheels benefit from unique expertise. Offered with a lifetime warranty and a generous replacement policy in the event of a crash, they represent the perfect alliance of innovation, durability and ultimate performance.
