The 303 brings a lot to the table, including heritage proven in the world's hardest races. At the center of the wheelset is Zipp''s 77/177 hubset, which results in improved stiffness, durability, simplicity and versatility. The carbon wheel that helped pioneer the Firecrest rim platform for improved aerodynamics and crosswind stability also features the unspoken durability that has repeatedly won Paris Roubaix and the Tour of Flanders
Firecrest rim technology affords the rider more speed, more stability, and more strength. This technology offers stable, predictable handling, and the wider rim increases lateral stiffness while offering greater vertical compliance
