Zipp 303 Firecrest

No, the Zipp 303 Firecrest rims are designed specifically for tubeless setups. You must use tubeless-ready tires, though you can run them with or without sealant depending on your preference.

The maximum tire pressure for these wheels is 73 psi. Because of the wide 25mm internal rim profile, you will likely find that running lower pressures provides better grip and comfort without sacrificing rolling efficiency.

The 40mm depth is designed to be a 'do-it-all' profile. It offers significant aerodynamic benefits on flat stretches while remaining stable and predictable when you encounter gusty crosswinds, making it a great choice for varied riding conditions.

Yes, the 303 Firecrest is highly capable on mixed surfaces. The wide internal rim width provides excellent tire support for wider gravel tires, and the robust ZR1 hub is built to handle the vibrations and debris common on unpaved roads.

These wheels are compatible exclusively with Center Lock disc brake rotors. You will need to ensure your rotors are compatible with the Center Lock standard before installation.

The maximum system weight—which includes the rider, the bike, and all gear—is 114 kg (250 lbs). This limit ensures the structural integrity and long-term durability of the carbon rim construction.
