Zipp 303 Firecrest® Force Disc Tubeless XDR Wheel Set

Zipp 303 Firecrest® Force Disc Tubeless Sram XDR Wheel Set

Zipp’s 303 Firecrest® Tubeless Disc Brake Rim is designed for the real world…a world of imperfections, road surfaces and, ultimately, simple elements. Efficiency = speed. Faster, lighter and more capable on a variety of terrains, whether the surface is all asphalt or no asphalt at all. Rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest has been purposefully rebuilt for the demands of modern road cycling.
Fast, light and versatile wheels: Zipp's 303 Firecrest Carbon Clincher
When it comes to going fast on a bike, efficiency is reduced: Wind resistance, rolling resistance, rider fatigue, weight. The 303 Firecrest Tubeless Disc-brake was designed using direct measurements from the real world (rather than primarily wind tunnel or computer simulation). The results were impressive. Its rim features a slightly bulgier design than its predecessor, with an outer width of 32 mm, an inner width of 25 mm and a rim depth of 40 mm. The profile provides low drag and an improved transition between rim and tire, improving aero efficiency on the road. The wide rim stance also offers less tire deflection for lower rolling resistance.

The combination of a wider tire, increased tire volume and lower tire pressure helps reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions – the tire and rim system absorbs the shock, not the rider. At the heart of the 303 Firecrest Tubeless Disc Brake is the German-engineered ZR1 DB, a versatile and durable new hub set. This hub set features 66 engagement points for quicker responsiveness. The 303 Firecrest Tubeless Disc Brake wheelset is for the dedicated cyclist who craves the latest technology. Compete against rivals… in races, against their peers or simply to conquer their personal limits. It’s about getting faster and matching your motivation with the most advanced technology.
