The allure of carbon combined alloy with proven Cosmic performance—fast, lightweight, strong and always reliable.

Lightweight, aero and efficient.

40mm NACA-inspired rim shape minimizes drag for added speed.

Reduced inertia of the lightweight rim delivers instant acceleration.

Mavic Road Tubeless UST improves rolling efficiency.

Versatile performance for all road riding conditions.

Minimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types terrain, from the flats to mountain climbs.

The Cosmic Pro Carbon has traditionally been favoured primarily for fast, flat races, but recent improvements have boosted this wheel's versatility.

Now it delivers incredible all-rounder performance at a price that can't be beat. Engineered with Mavic UST technology, the Cosmic Pro Carbon UST offers all the benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of flats.

The 40mm deep rims are NACA compliant for low drag and excellent crosswind stability, and their lighter weight results in reduced inertia for explosive acceleration and climbing efficiency.

The rims are made from Maxtal and 12K carbon fibre also feature Mavic's patented inter-spoke milling reducing the weight up to 40g making climbing and acceleration faster. 

Maxtal is an exclusive aluminium alloy that offers a higher strength to weigh ratio than conventional 6106 aluminium. The complete wheelset weighing in at 1650 grams excluding tyres. The wheelset is equipped with Mavic instant drive 360 giving superfast engagement and adjustable hub bearings allowing higher rolling efficiency with quick adjustment.
