With stunning acceleration, the new DURA-ACE R9270 C36 wheelset will change the way you experience climbs, corners, even stop lights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. With both a lighter, wider all-carbon rim and a lighter hub, the new DURA-ACE C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile the hub features an alloy FREEHUB body and new engagement mechanism for increased rigidity.

Zipp's 303 Firecrest Tubeless rim brake wheels offer all-around performance for a new era of road riding. They're rich in heritage yet loaded with innovations; as adept in the mountains as on rolling hills, windswept farm lanes, or ferocious field sprints. At Zipp, we never rest on laurels. These wheels feature a 19mm internal width and are tubeless ready. That means you can run lower tire pressure for greater cornering grip and compliance while still benefiting from reduced rolling resistance and without the risk of pinch flats. When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. They're lightweight and feature ABLC Sawtooth Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. The ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. Lastly, at the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hub, the German-engineered ZR1.

With a shallow-depth aero profile and lively acceleration, the ULTEGRA R8170 C36 wheelset is a climber's delight that delivers performance every road rider will appreciate.
