Imagine having access to the pinnacle of road racing performance—the same level of speed, acceleration and incredible ride quality that WorldTour pros demand—but without the need for your very own support car following you around. That's what you get with the new Cosmic Ultimate UST. It's the same superlight full-carbon design that has long been a pro favourite, but with the added reliability and puncture protection of our UST Road Tubeless system. The first thing you need to know is that the wheelset weighs only 1300g. That means you'll fly up the climbs and accelerate like a rocket ship. It's also super efficient, with a wind-slicing 40mm deep, 25mm wide full-carbon tubular rim profile, 20 super-bladed spokes, and high, thin carbon hub flanges. It’s also ultra-stiff thanks to the unidirectional carbon fibre spokes. 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 fibres wrapped over a super rigid foam core. And our unique iTgMax technology delivers reliable and consistent braking performance in both wet and dry conditions. The UST Road Tubeless setup, including our integrated Yksion Pro UST tires, saves about 15% in rolling resistance at equal tire pressure while being super easy to set up, inflate and maintain. It’s easy to see why the Cosmic Ultimate is the pro’s choice for the most challenging World Tour races. Now, with this UST version, it can also be yours.
