Zipp 404 Firecrest Wheelset

No, the Zipp 404 Firecrest wheels feature a hookless rim design that is strictly compatible with tubeless-ready tires only. You must run these as a tubeless setup to ensure safety and proper tire retention.

The maximum recommended tire pressure for this wheelset is 73 psi. Because of the wider 23mm internal rim width, you will likely find that running lower pressures provides better rolling efficiency and comfort without sacrificing speed.

While the 58mm rim depth is optimized for aerodynamics on flats and rolling terrain, the 1559-gram weight makes them surprisingly capable on climbs. They are designed as an all-around wheelset, so they perform well on varied courses rather than being limited to just flat time trials.

The German-engineered ZR1 hub is designed for durability and ease of service. With 66 points of engagement, it offers quick power transfer, and the internal seals are robust enough to handle varied weather conditions with minimal regular maintenance.

Yes, the maximum recommended system weight—which includes the rider, the bike, and any gear—is 114 kg (250 lbs). Staying within this limit ensures the structural integrity and performance of the carbon rims.

These wheels use a Center Lock disc brake interface. You will need Center Lock compatible rotors, which are standard for most modern disc-brake road groupsets.
