Zipp Wheels 303 S Carbon Tubeless Ready Disc

The Zipp 303 S Tubeless disc brake wheels provide all the versatility while maintaining the speed that all today's cyclists demand and want.

Greatly expanding on their legacy of conquest in the Spring Classics, the 303 S wheels retain their ideal all-terrain identity with a rim height of 45 mm, adding a significantly wider internal width to ensure greater performance and ride quality.
Right now, road bikes are more versatile than ever regardless of the road surface, but they keep their speed intact.
The 303 S has a redesigned design and rim profile to optimize the performance of any cyclist who wants to rely on this innovative new product. Tubeless, for disc brakes, the 303 S give the possibility of mounting wide tires, at low pressures, to be able to tackle even dirt roads.

The 303 S are among the lightest wheels in the Zipp range and are optimised for the best aerodynamic performance with a 28mm tyre, but can fit off-road tyres up to 50mm wide.
The significant innovation is in the design of the new 303 S; The outer width of the rim is increased by 2 mm, to 27 mm, and the tire bed is 7 mm wider, 23 mm inner width. The ability to inflate the tire to lower pressures helps reduce rolling resistance and consequently provides a more comfortable ride.
Translated into numbers, according to internal tests carried out by Zipp, traveling on a flat road at a speed of 40 km/h with a 28 mm tire allows you to save 10 watts.
Last but not least, a really interesting price and renewed graphics that will make you immediately visible within the group.
