Zipp 404 Firecrest Disc Centerlock Tubeless Wheels with Sram XDR 12-Speed Freehub Body

Zipp 404 Firecrest Tubeless wheels are a proven weapon for speed in any situation. With a depth of 58 mm, the wheels are ideal for road racing, time trials and triathlons, sportives and riding on varied terrain. The wheels' 23 mm internal width is perfect for using wider tubeless tyres at lower pressures. This is a vital component of Total System Efficiency™ (TSE™), an approach to speed across ever-changing roads and riding conditions. Specifically, TSE™ focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance and vibration losses. Zipp's ABLC™ Sawtooth™ technology uses an intricate dimple pattern to improve aerodynamic efficiency. With hookless construction, the transition between tyre and rim is smoother and more aerodynamic. Zipp's hookless rims have more efficient resin distribution, resulting in lighter, stronger wheels. At the heart of the 404 Firecrest Tubeless is a new versatile, durable hub, designed in Germany with an improved seal design for greater longevity and faster response with 66 engagement points.
