The Mavic Cosmic Ultimate 45 Wheelset represents the pinnacle of Mavic’s road racing wheel technology, engineered for riders who demand maximum speed, minimal weight, and absolute precision at the highest level of performance. Designed and built in Europe, the Cosmic Ultimate 45 is a no-compromise wheelset trusted by professional racers and elite climbers alike.
Featuring a 45mm full carbon rim, the Cosmic Ultimate 45 delivers an ideal balance of aerodynamic efficiency and low rotational weight, making it exceptionally fast on climbs, rolling terrain, and high-speed descents. The rim is optimized for modern road tires, providing excellent tire support, predictable handling, and reduced rolling resistance in real-world riding conditions.
What truly sets the Cosmic Ultimate 45 apart is Mavic’s one-piece carbon spokes (R2R – Rim to Rim) technology. These ultra-stiff, lightweight spokes are molded directly into the rim, creating a structure with exceptional power transfer, razor-sharp responsiveness, and precise tracking under load. The result is immediate acceleration and unmatched control during out-of-the-saddle efforts, sprinting, and aggressive cornering.
Paired with Mavic’s premium hub system and high-quality bearings, the Cosmic Ultimate 45 delivers smooth rolling efficiency and long-term reliability, making it a top-tier choice for race-day builds and high-performance road bikes where every watt matters.
