Details

Zipp's 303 Firecrest Tubeless rim brake wheels offer all-around performance for a new era of road riding. They're rich in heritage yet loaded with innovations; as adept in the mountains as on rolling hills, windswept farm lanes, or ferocious field sprints. At Zipp, we never rest on laurels. These wheels feature a 19mm internal width and are tubeless ready. That means you can run lower tire pressure for greater cornering grip and compliance while still benefiting from reduced rolling resistance and without the risk of pinch flats.

When it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. They're lightweight and feature 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. The ShowStopper textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. Lastly, at the center of the 303 Firecrest Tubeless rim-brake is a new versatile and durable hub, the German-engineered ZR1.

- Tubeless for secure performance even when ridden at lower tire pressures
- New ZR1 hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement
- 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
- New Zipp graphics and cosmetic identity that scream speed
- Ships with QR end caps, quick release skewers

Showstopper

Our industry leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.

ABLC SawTooth

ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel.

AeroBalance

Zipp’s sole mission is to help you go faster. That's why our wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, our engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.

Tubeless technology

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
