Description

The MAVIC COSMIC ULTIMATE 45 wheelset lives up to its name: "Ultimate" stands for absolute excellence. Developed to offer the ultimate in performance, they combine extreme lightness, rigidity and aerodynamics in a package weighing just 1260 g. Compatible with tubeless and clincher tires, as well as disc brakes, it is aimed at the most demanding cyclists in search of speed, reliability and unique sensations.

Its carbon rim, with a NACA profile of 45 mm and an external width of 32 mm, combines aerodynamic efficiency and stability. A complex assembly optimizes the rim's weight/stiffness ratio, while the superimposition of Adaptative Lay Up layers saves 70g in weight. Undrilled, the rim requires no rim tape for waterproofing, guaranteeing simple, worry-free tubeless use.

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

On the spoking side, R2R (rim-to-rim) technology makes all the difference. The 20 elliptical unidirectional carbon-fibre spokes are continuous, passing through the hubs to form a monobloc structure. This design significantly increases rigidity, improves aerodynamics and eliminates the weak points associated with traditional fasteners.

The carbon hubs feature ceramic bearings for smooth, long-lasting operation and premium performance. At the rear, the ID360 freewheel system ensures instant engagement with its 40 points, for explosive relaunching and transmission without loss of energy. Designed for through axles (12x100 / 12x142) and Center Lock disc brakes, this pair is perfectly suited to modern bikes.

Entirely handcrafted in France at Mavic's carbon workshop in Annecy, the Cosmic Ultimate 45 Discs benefit from unique know-how. Offered with a lifetime warranty and a generous drop-in replacement policy, they represent the perfect blend of innovation, durability and ultimate performance.
