Zipp 303 Firecrest Tubular Wheels

The Zipp 303 Firecrest Tubular rim brake wheelset delivers key innovations for performance-minded riders. It’s the revolutionary wheelset designed to conquer Roubaix and Flanders. Maintaining their versatile 45mm rim depth, the 303 Firecrest Tubular rims feature construction designs for impact protection. When it comes to pure speed, the Zipp 303 Firecrest Tubular packs a punch. It’s lightweight with ABLC™ Sawtooth™ technology, a complex dimple pattern first developed for our top-tier NSW wheel line. This technology helps optimize low aerodynamic drag and crosswind stability, which we call AeroBalance™. Zipp ’s ShowStopper™ textured braking surface delivers unmatched rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubular rim brake is a new versatile and durable hub,

Technologies

Showstopper™

Our industry-leading Showstopper™ silicone carbide brake track continues to evolve and improve, delivering unmatched stopping power and modulation regardless of weather conditions or descent length.

ABLC Sawtooth™

Our new ABLC Sawtooth footprint design features 12 nodes that are specifically spaced so that aerodynamic shear takes effect at a frequency of 50 Hz when the rider is riding at 24 km/h. Sawtooth accomplishes this by inducing small vortex sheets that flow at a low intensity but higher natural frequency, reducing the laminar bubble effect on the opposite side of the rim profile exposed to the wind, further reducing high drag and improving stability in crosswinds.

AeroBalance™

AeroBalance™ simultaneously reduces both aerodynamic drag and side force

XDR™

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.
