Zipp has released new versions of their 303, 404 and 808 range which they claim brings more speed, better braking, greater stability and also reduced weight. See their press release below.


Innovation permeates all we do. To that end, Zipp Firecrest Carbon Clincher rim-brake wheels now offer best-in-category aero efficiency and stability – a speed-inducing combination we call AeroBalance – along with greater stopping power at our most popular rim depths:
303 Firecrest (45mm rim depth) – An all-around performer as adept in the mountains as it is on rolling hills, or a field sprint.
404 Firecrest (58mm rim depth) – Our all-time best seller because it’s all about aero, while also being nimble on climbs and corners.
808 Firecrest  (82mm rim depth) – An all-out aero weapon preferred by  triathletes, time trial specialists or any cyclists with the need for speed.
These wheelsets feature technologies previously only available in Zipp’s halo-level NSW lineup. This migration of technology allows NSW wheels to be the repository for Zipp’s most cutting-edge designs, which then eventually are shared across the wheel lineup as new NSW wheels are refreshed with new features.
More Speed: Revised rim profile for reduced aerodynamic drag developed by our advanced development team in Indianapolis, Indiana, USA.
Greater AeroBalance: ABLC  Sawtooth Technology, a complex dimpling pattern that helps reduce high yaw drag while improving crosswind stability.
Better braking: Zipp’s ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions.
Lighter Weight: At each rim depth, the new Firecrest rim brake wheelset is lighter than its predecessor.
Every Firecrest rim is designed and made by hand in Indianapolis. At the center of these wheels is the pro-proven 77/177 hubset. The 177 rear hub is also XDR driver body compatible for use with SRAM 10-42 cassettes
