Zipp 404 FireCrest Wheel

No, the 404 Firecrest features a hookless rim profile, which requires the use of tubeless or tubeless-ready tires. You can run these tires with inner tubes, but the tire itself must be tubeless-compatible.

The wider internal width allows you to run wider tires at lower pressures. This increases the contact patch for better grip, reduces rolling resistance, and helps dampen road vibration, which ultimately keeps you faster and more comfortable over long rides.

The wheel ships with either an XDR or SRAM/Shimano driver body, covering the vast majority of modern road groupsets. If you ride Campagnolo, you will need to purchase a separate compatible driver body.

Zipp optimized the tire bed on these rims to make tire installation significantly easier than previous generations. While tubeless tires can sometimes be tight, the design allows for a more seamless, aerodynamic transition between the tire and rim.

The German-engineered ZR1 DB hub is designed for durability with an improved seal design to keep out debris. With 66 points of engagement, it offers quick response, but like any high-performance hub, it should be serviced periodically to ensure the bearings and engagement mechanism remain smooth.

While the 404 Firecrest is optimized for road racing, time trials, and triathlons, its 58mm depth and wide internal profile make it capable on smoother gravel or mixed-terrain roads. However, if you are riding primarily rough, technical gravel, you might prefer a shallower, more impact-resistant wheelset.
