FAQs

What valve type does the AV4 use?

The AV4 uses a Schrader valve.

Is the AV4 suitable for all types of cycling?

It is suitable for general cycling, commuting, and use with Brompton bikes. Ensure the correct tire size compatibility.

How do I find the correct tire size?

The tire size is printed on the sidewall of your tire. The AV4 is compatible with the sizes listed in the compatibility section of this guide.

How often should I check the tire pressure?

Check your tire pressure before each ride, or at least once a week.

What should I do if I get a flat tire?

Remove the wheel, locate the puncture, and either patch the tube or replace it with a new one.

Can I use tire sealant with the AV4?

While it's possible, it is not recommended. Tire sealant can sometimes react with the butyl rubber.

Store spare tubes in a cool, dry place, away from direct sunlight.

Troubleshooting

Tire deflates quickly.

Check for punctures in the tire and tube. Locate the puncture, and replace or patch the tube.
