Zipp 404 Firecrest Disc Centerlock Tubeless Wheels Sram XDR 12v Hub

The Zipp 404 Firecrest Tubeless wheels are a proven speed weapon for any situation. With a depth of 58 mm, the wheels are ideal for road racing, time trials and triathlons, gran fondos, and riding on varied terrain. The 23 mm internal width of the wheels is perfect for using wider tubeless tires at lower pressure. This is a vital component of Total System Efficiency™ (TSE™), an approach to speed on roads and riding conditions that are always changing. Specifically, TSE™ focuses on overcoming speed-specific barriers: wind resistance, gravity, rolling resistance, and vibration losses. Zipp’s ABLC™ Sawtooth™ technology uses an intricate dimpling pattern to improve aerodynamic efficiency. With hookless, the transition between tire and rim is smoother and more aerodynamic. Zipp’s hookless rims have a more efficient resin distribution, meaning lighter and stronger wheels. At the heart of the 404 Firecrest Tubeless is a new versatile and durable hub, designed in Germany with improved sealing design for longer life and quicker engagement with 66 points of engagement.
