The best combination of light stiff and aero proven in the UCI World Tour by the world’s top road cyclists. These are the Formula One of road racing wheels.

Key benefits

Unbeatable pro-level ride quality and stability.

40mm deep and 25mm wide rims integrate perfectly with 25mm or wider tires NACA profile provide unbeatable crosswind stability

Ultralight weight helps you climb sprint and accelerate faster.

Rims spokes and hubs feature a full carbon monobloc construction. for minimum weight and maximum rigidity.Incredibly light at only 1250g.

Stiffest wheel system in its class gives you sharp handling and maximum power transfer.

R2R full carbon spoke technologyNo spoke drilling ensuring maximum rigidity and strengthAsymmetrical rear rim profile for maxium power transfer

Ultimate is not just a name it’s the word we reserve for perfection. And it’s how we define this wheelset.

The Cosmic Ultimate was introduced 10 years ago and quickly became the wheel choice for pro racers seeking a competitive advantage. With a NACA-inspired 40mm deep 25mm wide full-carbon tubular rim profile 20 super-bladed spokes and high thin carbon hub flanges it offers a clear and proven aero advantage.

It’s also ultra-stiff thanks to the unidirectional carbon fiber spokes that don’t stretch. These spokes run continuously from one edge of the rim to the other through the hubs (R2R technology) creating one single spoke instead of two. This eliminates the need to mechanically attach the spokes to the hub.

The rear rim is asymmetrical to improve the drive-side bracing angle so spoke tension is balanced and the wheel stays stiff under the heaviest lateral loads such as sprints or attacks. The rim is made of 12k carbon fibers wrapped over a super rigid foam core. Full-carbon construction means the whole wheel is incredibly light at just 1250g.

Our unique iTgMax technology delivers reliable and consistent braking performance in both wet and dry conditions. It’s no surprise the Cosmic Ultimate is pro’s choice for the most challenging World Tour races.
