Description of ZIPP 303 Firecrest Carbon Showstopper Rear Wheel - Clincher - QR - black

Innovation permeates all Zipp does. To that end, Zipp Firecrest wheels now offer best-in-category aero efficiency and stability – a speed-inducing combination Zipp calls AeroBalance – along with greater stopping power.

The Firecrest AeroBalance carbon clincher rim brake wheels feature technologies previously only available in Zipp's halo-level NSW lineup. Firecrest carbon clinchers, first introduced in 2010, offer durability for everyday riding and race-ready performance with the ease of use of clinchers. Each wheel has key innovations, starting with a revised rim profile for reduced aerodynamic drag developed by Zipp's advanced development team in Indianapolis. In addition, the rims feature ABLC Sawtooth Technology, a complex dimpling pattern that helps reduce high yaw drag and improve crosswind stability. When it comes time to slow down, Zipp's ShowStopper textured braking surface delivers unrivaled rim braking performance in all conditions.

The 45mm deep, symmetrical rim is completely made of carbon for a high sprinting stiffness at an extra low weight. The wheel is equipped with a Zipp 177 hub and 24 double crossed Sapim CX-Sprint spokes.

Technologies of ZIPP 303 Firecrest Carbon


Showstopper™ is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin. Includes 317 groves on each side of the wheel that are directional to wheel rotation to increase stopping power and help clear away water from the braking surface. Delivers equal braking force in wet conditions when compared to industry leading aluminum rims.

ABLC™ SawTooth™ Technology (Aerodynamic Boundary Layer Control)

The 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 rim’s profile to further reduce high yaw drag and improve crosswind stability.


With the new proprietary Firecrest rim shape in Zipp's 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds and overall ride quality.

Carbon Clincher

Zipp's superior Carbon Clincher technology is the culmination of two years of intensive prototyping and testing. They worked with their composites supplier to develop an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards.
