The 2021 model of the US premium manufacturer’s elegant 303 S carbon rear wheel is the official successor of last year’s highly popular ZIPP 302 and is made for high-quality performance at a fantastic price.

ZIPP has put the focus on a completely overhauled rim profile and full tubeless compatibility to fit modern disc brake designs. The 303 S series also borrows design elements, such as the total system efficiency concept, from the higher-level 303 Firecrest™ disk brake wheelset.
The high-end carbon rims have been adapted to the needs of modern cyclists, with a 45 mm high tread and an impressive 23 mm inner rim width with an outer width of 28 mm. Thanks to this the hookless rims of the ZIPP 303 S rear wheel are aerodynamically optimised for 28 mm wide tubeless road tyres, though they also fit well to 50 mm wide tyres.
In other words, there is nothing standing in the way of your racing ambitions on paved streets, challenging rides on dusty gravel, or heated fights for the best position in cyclo-cross competitions.
