FAQs

Can I use inner tubes with these wheels?

Yes, but you must use a tubeless-ready tire that is certified for hookless rims, even if you are installing an inner tube inside it.

What is the maximum tire pressure?

The maximum tire pressure for the Zipp 303 S is 73 psi (5 bar).

Are these wheels compatible with rim brakes?

No, the Zipp 303 S is designed exclusively for disc brake systems.

Can I run 25mm tires on this rim?

Zipp recommends a minimum tire width of 28mm to ensure safety and proper fit on the wide hookless rim profile.

How do I check if my tire is hookless compatible?

Check the tire sidewall for a 'Tubeless Ready' or 'Hookless Compatible' marking, or consult the tire manufacturer's online compatibility chart.

Does the wheel come with a center-lock nut?

The wheel typically includes the necessary hardware; however, always verify the contents of your specific retail package.

Troubleshooting

Difficulty seating the tire bead

Ensure the tire is rated for hookless rims and use a soapy water solution around the bead to help it slide into position.

Loss of air pressure

Check the valve stem core for tightness and ensure an adequate amount of tubeless sealant is present inside the tire.

Brake rub or squeal

Verify that the center-lock nut is torqued to specifications and check for rotor alignment with the brake pads.

Pros and Cons

Pros

Improved rolling efficiency at lower pressures
Excellent versatility for both road and gravel use
Stable handling in varied wind conditions due to 45mm depth
Seamless tire-to-rim interface reduces drag
Durable hub construction

Cons

Requires tubeless-compatible, hookless-compliant tires
Not compatible with rim brakes
Hookless design limits maximum tire pressure to 73 psi (5 bar)

Setup, Compatibility & Care

To ensure optimal performance, the Zipp 303 S must be set up with tubeless-ready tires that are officially approved for use on hookless rims. When mounting tires, use a high-volume floor pump or a tubeless booster pump to seat the beads effectively. Check your tire manufacturer's pressure chart, as the maximum inflation pressure for this wheel is strictly 73 psi (5 bar). Maintenance is straightforward: clean the rim surfaces with mild soap and water to remove debris, and periodically inspect the hub bearings for smoothness. Always verify that your disc brake rotors are center-lock compatible before installation.
