ZIPP 404 Firecrest carbon wheels 58mm tubeless tyre/rim brake 2024

Zipp 404 Firecrest Wheels

Zipp 404 Firecrest wheels , Zipp 's ultimate weapon for speed, are better than ever. This versatile rim brake wheelset is, for the first time ever, tubeless compatible. This means you can opt for lower tire pressure to gain more forgiveness and cornering grip and reduce rolling resistance without the risk of a pinch flat. The 58mm rim height of this wheelset is a classic feature that has brought athletes to victory in all sorts of events and situations: all distances in triathlons, long distance breakaways, sprints and finishes. by rating. Zipp 's ABLC™ Sawtooth™ technology employs an intricate dimple pattern to improve aerodynamic efficiency. Zipp 's ShowStopper™ Textured Braking Surface delivers unmatched rim braking performance in wet and dry conditions. At the heart of the 404 Firecrest tubeless rim brake is the ZR1, a new all-around, rugged hub designed in Germany. If you need to choose a single wheel for the road and competition, the wisest choice is to opt for the Zipp 404 Firecrest tubeless known for its speed.

Technology

Showstopper™

Our industry-leading silicone carbide Showstopper™ drag track continues to evolve and improve, delivering unmatched stopping power and modulation regardless of weather conditions or length of descent.

ABLC Sawtooth™

Our new ABLC Sawtooth footprint design features 12 nodes that are specifically distributed so that aerodynamic shear takes effect at a frequency of 50 Hz when the rider is riding at 24 km/h. Sawtooth accomplishes this feat by inducing small vortex sheets that flow at low intensity, but at a higher natural frequency, thereby decreasing the laminar bubble effect on the opposite side of the rim profile exposed to the wind, to further reduce the strong drag and to improve stability against side winds.

AeroBalance™

AeroBalance™ simultaneously reduces both aerodynamic drag and side force

XDR™

The XDR™ driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR™ interface is 1.85mm longer than XD™ and is designed for road hub applications. XDR™ driver bodies are compatible with all XD™ cassettes when the cassette is installed with a 1.85mm spacer.

Guarantee
