Zipp 404 Firecrest Wheel

No, the Zipp 404 Firecrest features a hookless rim profile, which is designed exclusively for tubeless-ready tires. You must use tubeless-compatible tires, though you can run them with or without sealant depending on your preference.

While deeper rims can be notoriously twitchy, the 404 Firecrest utilizes Zipp's ABLC Sawtooth dimple design. This pattern helps manage airflow across the rim surface, significantly improving stability and predictability in gusty conditions compared to standard deep-section wheels.

While these are primarily designed as road wheels, the 23mm internal rim width provides a stable platform for wider tires. They are capable of handling light gravel or rough pavement, but they are optimized for speed and aerodynamics rather than heavy-duty off-road durability.

The high engagement count means there is very little 'dead space' when you start pedaling. This results in near-instant power transfer, which is particularly noticeable when accelerating out of corners or navigating technical, punchy climbs.

Yes, these wheels are designed for Centerlock disc brake rotors. You will need to ensure your rotors are compatible with the Centerlock standard, which is the industry norm for modern disc-brake road wheelsets.

Zipp offers a lifetime warranty on these wheels. This covers defects in materials and workmanship, as well as damage that occurs while riding, providing significant peace of mind for an investment of this caliber.
