Zipp 404 Firecrest Tubeless Rim 700c Front Wheel

Zipp’s legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake wheelset is, for the first time, tubeless ready. That means you can run reduced tyre pressure for reduced rolling resistance and increased cornering grip and compliance without the risk of pinch flats. This wheelset’s 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation – every triathlon distance, breakaways, field sprints and hilly finishes. Zipp’s ABLC™ Sawtooth™ Technology uses a complex dimpling pattern to improve aero efficiency. Zipp’s ShowStopper™ textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the center of the 404 Firecrest Tubeless rim-brake is a versatile and durable new hubset, the German engineered ZR1. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.

Technologies

Showstopper

their 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 their 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, Zipp’s 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 their new HexFin ABLC dimples for improved airflow.
