Zipp Wheel - 404 Firecrest Carbon Tubeless Disc Brake Center Locking 700C Rear

The Zipp 404 Firecrest Tubeless Disc Rear Wheel is built for riders who want proven aero speed without sacrificing versatility. With its 58mm carbon hookless rim, wide 23mm internal profile and tubeless-only design, it gives serious road riders a fast, efficient platform for racing, triathlon, gran fondos and high-speed training.

The 404 Firecrest is designed around Zipp’s Total System Efficiency approach, targeting the real-world forces that slow riders down: wind resistance, rolling resistance, gravity and vibration losses. Its ABLC Sawtooth surface texture helps improve aerodynamic performance, while the wider rim profile supports modern tubeless tyres at lower pressures for better comfort, grip and efficiency across varied road surfaces.

At the rear, the German-engineered ZR1 Disc Brake hub delivers durability, improved sealing and fast engagement through its 66 points of engagement. Combined with Centre Lock disc brake compatibility and a SRAM/Shimano Road driver body, this is a premium rear wheel built to deliver race-ready speed and dependable performance across changing conditions.
