In the past two years, the 303 has emerged as one of the most formidable wheels in the Pro Peloton, with wins in the Tour de France, Paris-Roubaix, the Tour of Flanders, and more. Its speed, light weight, and utter reliability have been proven in pro cycling's most demanding races.

The 303 has been completely redesigned with Firecrest shaping. The Carbon Clincher preserves the aerodynamic advantages of its tubular brother, while adding the convenience of a clincher tire. And at just 1498 grams, it's light enough to climb up the steepest gradients with ease.

All of the hallmark characteristics of the 303 have improved with the Firecrest Carbon Clincher. The Firecrest shaping optimizes the aerodynamic profile of both the front half and the back half of the wheel. In addition, Firecrest moves the center of pressure of the wheel backwards, giving the 45mm-deep rim the crosswind stability a box-section rim. At the same time, the 26.2mm-wide brake track allows the clincher tire to take on a wider, more stable shape without compromising rolling resistance. It's faster, simpler, and more stable. Or as technical director Josh Poertner puts it, Firecrest is “lightning in a bottle.”
