Zipp 404 Firecrest wheels have been icons of cycling speed for the last three decades, and now, they're updated with the latest developments in aerodynamics and tubeless technology.
The 404's heritage as Zipp's icon of speed extends back decades, and its future is even brighter. At 58mm deep, the 404 Firecrest Tubeless is ideal for road races, time trials and triathlon, and gran fondos.
The wheelset's 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency, or TSE, an approach to speed on 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 dimpling pattern to improve aero efficiency.
Zipp's use of hookless (straight side) rims in the 404 Firecrest is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter, stronger wheels.
Outdoor testing commissioned by Zipp revealed the real-world gains of Zipp TSE. A bike-and-rider system weighing 85kg (187lbs) on the new 404 Firecrest with 25mm tires required 286 watts to maintain a speed of 40kph. That's a 4-watt saving compared with the previous model 404 Firecrest.
At the center of the 404 Firecrest Tubeless Disc-brake is a versatile and durable hubset, the German-engineered ZR1 DB. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless Disc brake is a savvy and speedy choice.
*Lightest configuration: 12mm through axles and XDR body. No tape or valve included in weight.
