Road bikes are ever evolving and ever inspiring. The 404 Firecrest Carbon Clincher Tubeless Disc brake wheel offers cyclists the chance to experience best-in-class aero efficiency and stability with the benefits of tubeless compatibility along with a purpose-built rim shape for disc brakes and wider tire options.
Zipp's 404 Firecrest Tubeless Disc is all about road riding and racing. In use at the highest levels of professional cycling and triathlon, disc-brakes are poised for growth in all sorts of road riding. As for speed, the 404 Firecrest is where the Firecrest Revolution began. If you had to choose just one wheel, the 404 Firecrest should be your choice.
Without the constraints of rim brake caliper compatibility or brake-track requirements, the new Firecrest Carbon Clincher Tubeless Disc-brake wheel offers the increased stopping power and modulation of disc brakes and a whole lot more.
To maximize the aero performance of the wheels, Zipp's ABLC dimples extend all the way to the outer edge of the disc-specific rims. The new wheels are also optimized for wider tires to meet the performance needs of modern riders in search of low rolling resistance and aero efficiency with high comfort. The 404 Firecrest Tubeless Disc brake has an internal width of 19 mm and is aerodynamically optimized for 25 mm wide tires. The refined rim shape improves Firecrest's ability to yield low aerodynamic drag and high crosswind stability, a combination Zipp calls AeroBalance.
A new carbon fiber layup for the Indianapolis-made rims keeps weight low while maintaining the Firecrest Carbon Clincher's proven durability. The robust 177D hub, paired with 24 Sapim CX-Ray spokes, keeps the wheels stiff and responsive. To ensure compatibility with any bike, the versatile hub comes with swappable end caps to work with QR's and thru-axles, including 12x142 mm thru-axles.
