Mavic Cosmic Ultimate Disc Road Wheelset The Mavic Cosmic Ultimate Centre Lock Disc Road Wheelset stands as the pinnacle of carbon engineering, representing the most advanced all-round wheelset ever produced by the brand. Weighing a remarkable 1260g, this full carbon masterpiece combines a 45mm deep profile with a modern 23mm internal width to deliver a ride that is as fast as it is light. Every element is designed for the competitive cyclist who demands absolute excellence, offering a transformative upgrade that excels whether you are contesting a mountain summit or leading out a high speed sprint. Unmatched Power Transfer with R2R Carbon Spokes The defining feature of this wheelset is the R2R carbon spoke technology, where a single continuous carbon spoke spans the entire width of the wheel from one rim edge to the other. This unique construction creates a perfectly balanced system with incredible lateral stiffness, ensuring that every ounce of your energy is converted into forward motion. These extra flat spokes are not only aerodynamically optimised but are also engineered to provide vertical compliance, offering a surprisingly comfortable and controlled ride quality even during the most intense efforts. Elite Materials and Adaptive Construction Performance is further refined through an adaptive carbon layup which strategically places material only where strength is required, shedding up to 70g per rim to make your bike feel incredibly lively on steep gradients. To ensure the wheels spin with minimal resistance, Mavic has equipped them with premium ceramic bearings, low density grease, and ultra slick seals for long lasting durability and maximum speed. Complete with UST Tubeless compatibility and a 100% carbon fibre build, the Cosmic Ultimate is the definitive choice for riders seeking the ultimate combination of weight, stiffness, and aerodynamic efficiency.  What's in the box  Wheelset User guide Wheel Cover UST valve not mounted on the wheel 2 Multifunction adjustment wrenches with the rear wheel
