Zipp 404 Firecrest Carbon Tubeless Rear Wheel

Zipp 404 Firecrest Carbon Tubeless Rear Wheel

Zipp’s legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake rear wheel 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 rear wheel’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 centre of the 404 Firecrest Tubeless rim-brake is a versatile and durable hub, 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.

ABLC Sawtooth

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