  • Cosmic Ultimate

    The best combination of light, stiff and aero, proven in the UCI World Tour by the worldís top road cyclists. This is the Bugatti Chrion of bike wheels

    Road wheelsets are delivered as Wheel-Tyre system

    Ultimate is not just a name, itís the word we reserve for perfection and how we define this Wheel-Tire System.
    It was first 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. Itís also ultra-stiff thanks to the unidirectional carbon fiber spokes that simply donít 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, eliminating 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. The system is delivered with Yksion Pro tubular tires, optimized for front and rear performance.
    The front uses GripLink with a tread pattern that improves water evacuation when leaning through corners and the rear offers minimum rolling resistance with grooves that release pressure on the ground but deliver plenty of traction in the rain thanks to the water evacuation channel. Itís no surprise the Cosmic Ultimate is proís go-to choice for the most challenging World Tour races.
