Versatile Endurance Wheelset for the Modern Road Cyclist — 303 Firecrest
Zipp's 303 Firecrest Tubeless Rim Brake wheelset is an all-around wheelset for a new era of road riding. It's rich in heritage yet loaded with innovations. It's as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints.
This wheelset features a 19mm internal width and is tubeless ready. That means you can run lower tire pressure for greater cornering grip and compliance with reduced rolling resistance without the risk the pinch flats. When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch.
It's lightweight with ABLC™ Sawtooth™Technology, a complex dimpling pattern first developed for our top-level NSW wheel lineup. This technology helps to achieve the optimization of low aerodynamic drag and crosswind stability, which we call AeroBalance™. Zipp's ShowStopper™ textured braking surface delivers unrivaled rim braking performance in wet or dry conditions.
At the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hubset, the German-engineered ZR1.
Features:
New Zipp graphics and cosmetic identity that scream speed
New ZR1 hub 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
Tubeless ensuring secure performance even when ridden at lower tire pressures
Versatile 45mm rim profile that's fast, stable and versatile
ABLC Sawtooth™ dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel
Showstopper™ textured brake track delivers superior modulation and shortest stopping distances in wet and dry conditions
XDR™ or SRAM/Shimano driver bodies
Ships with QR end caps, quick release skewers
Campagnolo driver body sold separately
Hook bead, allowing you to run a tube-type tire or a tubeless specific tire.

Easy Setup On A Fast Wheel

Bought these as a wider gravel wheel and an aero road wheel for 28mm plus tires. Have carbon wheel experience with several versions of Reynolds Assault and Attacks. I liked them... but the Zipps are SOOOO easy to set up, the hookless rim with Panaracer gravel or Pirelli road tubeless tires. After struggling so much with the Reynolds over the years, these are pure pleasure. Hookless has changed my mind about the hassel of tubeless. Now I have no problem going back and forth from gravel tires to road. The 303 Firecrests are light and climb well, responsive, and comfortable. In hilly New England gravel rides they are an asset. 500 + miles so far, no issues and trust it will stay that way. Make sure you check your front thruaxle size to insure the hub inserts shipped with wheels (15mm?) are the right size for your bike. I needed 12mm and had to order them after the wheels arrived. Cheers!

Have these on my gravel bike with Rene Herse Snoqualmie Pass (44mm) tires set up tubeless. My first ride with them I nabbed a bunch of PRs. They are light, responsive, I guess a little aero, and just pretty much awesome. The hubs engage instantaneously, the sound is nice (not too loud, not too soft), and did I say they are light? My bike flies up hills with these wheels. Can't comment on durability as I've only got 500 miles on them, but so far so good.
