Zipp Wheel - 404 Firecrest Carbon Tubeless Disc Brake Center Locking 700c Front 24Spokes 12x100mm Standard Graphic B1:

The Zipp 404 Firecrest Tubeless Disc is the benchmark aero road wheel for riders who want one wheelset that can do almost everything. Fast enough for road racing, stable enough for long days in changing conditions and efficient enough for triathlon, time trial and gran fondo use, it is a proven performance upgrade for serious riders.

With its 58mm rim depth, the 404 Firecrest delivers a clear aerodynamic advantage without becoming a specialist-only wheel. The wide 23mm internal profile supports modern tubeless tyre set-ups, helping riders run lower pressures for improved comfort, grip and efficiency on real-world roads.

Zipp’s Total System Efficiency approach is what makes the 404 more than just a deep-section carbon wheel. By targeting wind resistance, rolling resistance, gravity and vibration losses together, it is designed to help riders carry more speed across varied terrain, imperfect surfaces and changing conditions.

ABLC Sawtooth surface dimpling improves aerodynamic performance, while the hookless carbon rim creates a cleaner tyre-to-rim transition. At the centre, the German-engineered ZR1 Disc Brake hub adds durability, improved sealing and quick 66-point engagement, making the 404 Firecrest a premium wheelset built for repeated high-performance use.
