Zipp Wheel - 404 Firecrest Carbon Tubeless Disc Brake Center Locking 700c Rear 24Spokes 12x142mm Standard Graphic B1

OVERVIEW
The Zipp 404 Firecrest Tubeless Disc brake is a pro-proven speed weapon designed for any situation. Its heritage as an icon of speed extends back decades, and its future is even brighter. At 58mm deep, this wheel is ideal for road races, time trials, triathlons, and gran fondos. The 23mm internal width is perfect for running wider tubeless tires at reduced air pressure, a vital component of Total System Efficiency™ (TSE™). This approach focuses on overcoming the four key barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses.

Zipp’s ABLC™ Sawtooth™ Technology uses an intricate dimpling pattern to improve aero efficiency, while the use of hookless (straight side) rims ensures a more seamless transition between the tire and the rim. This design results in more efficient resin distribution, creating a lighter, stronger wheel. At the center is the German-engineered ZR1 DB hubset, providing versatility and durability for those who want one wheel that can do it all.
