Zipp 303 Firecrest ® Tubeless Disc Brake Wheels are built for the real world… a world where conditions and roads are imperfect and the end goal is simple. Efficiency equals speed. They’re faster, lighter, and more capable on any terrain, from good to bad roads to trails. True to Zipp ’s commitment to dominating the early-season Classics, the new 303 Firecrest wheels have been redesigned to meet the demands of modern road bikes. When it comes to going fast on a bike, efficiency equals speed by reducing these elements: wind resistance, rolling resistance, rider fatigue, and weight. The 303 Firecrest Tubeless Disc Brake Wheels were designed using direct real-world measurements (not primarily wind tunnels or computer simulations). The results were impressive. The rim is slightly more dished than the previous version, with an external width of 32mm, an internal width of 25mm and a rim height of 40mm. The profile provides low drag and a better transition between the rim and the tire, which improves aerodynamic efficiency on the road. The rim width also helps reduce tire deformation, which lowers rolling resistance. With the combination of a wider tire, greater internal volume and lower pressure, rider fatigue can be reduced by smoothing out road imperfections: the tire and wheel absorb the vibrations, not the rider. At the heart of the Zipp 303 Firecrest Disc Tubeless Disc Brake Wheelset is the ZR1 DB, a new versatile and durable hub designed in Germany. For faster response, this hub features 66 points of engagement. The 303 Firecrest Tubeless Disc Brake Wheelset is for the serious rider looking for the latest technology. In a spirit of competition... in a race, against friends or simply to exceed your personal limits. The goal is to become faster and to match your motivation with the most advanced technologies.
Advanced Boundary Layer Control (ABLC) refers to the patented, instantly recognizable pattern found on all our carbon rims. ABLC, which attenuates airflow across the rim surface, is tailored to each model, from the 202 to the Super-9. The third generation of ABLC offers four times more footprints than before.
Total System Efficiency
AeroBalance™ simultaneously reduces both aerodynamic drag and side force
The XDR™ driver body is a universal mounting system for cassettes that incorporates cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR™ interface is 1.85mm longer than XD™ and is designed for road hub applications. XDR™ driver bodies are compatible with all XD™ cassettes when the cassette is installed with a 1.85mm spacer.
Zipp wheels, handlebars, stems and seatposts are guaranteed for life against damage that occurs while riding. Lifetime warranty is not transferable. Proof of purchase is required.
