Without Limits
Zipps 303 Firecrest Tubular rim-brake wheel offers key innovations for performance-minded cyclists. This is the game-changing wheel designed to conquer Roubaix and Flanders. Retaining their versatile 45mm rim depth, 303 Firecrest Tubular rims feature construction designs for impact protection. When it comes to pure speed, the 303 Firecrest Tubular packs a serious punch. Its lightweight with ABLC Sawtooth Technology, a complex dimpling pattern first developed for Zipp`s top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance. Zipps ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. At the center of the 303 Firecrest Tubular rim-brake is a new versatile and durable hubset, the German-engineered ZR1.
Highlights
- New Zipp graphics and cosmetic identity that scream speed
- Go-anywhere 45mm rim depth tubular pro-proven in the Spring Classics
- New ZR1 hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement
- Built with Sapim CX Sprint J-bend spokes
- Ships with QR end caps, quick release skewers
- Showstopper textured brake track delivers the best modulation and shortest stopping distances in wet and dry conditions

Technologies
ABLC® SawTooth®
Zipp`s new Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rims profile to further reduce high yaw drag and improve crosswind stability.
Firecrest
Zipp`s proprietary Firecrest® rim rewrote the fundamentals of wheel making, resulting in improved aerodynamics, ride quality, wheel strength and stability in even the strongest of crosswinds. As a result, the entire Firecrest family of wheels - from the 202 to 808 Firecrest - makes a bigger difference in more ways than ever including being laced into the new 77/177 hubset.
Firecrest technology, with rims that maintain a near-constant width almost all the way to the spoke bed, is the first aero profile that effectively controls airflow around the back half of the wheel. By moving the center of pressure - the focal point of side forces on the rim - to its optimal location near the steering axis, Firecrest offers stable, predictable handling at every wind angle. As they discovered when developing the Zipp 303 to thrive under unforgiving conditions at the Spring Classics, a wider rim such as used in Firecrest wheels increases lateral stiffness for sprinting and cornering, yet offers greater vertical compliance for more control, comfort, and durability on rough surfaces.
