PRESTA VALVES: Frequently asked questions

Do I need to use sealant in these tubes?

No, and most people will not use sealant in these tubes.

How do these tubes fit so many tyre sizes?

Unlike tyres, inner tubes are quite flexible and therefore can fit a range of tyre sizes.

How do I know if I'm buying the right size tube?

The correct size tubes fit to your tyres. Please double check the product description for sizing information.

What happens if I use the wrong size tube for my tyre?

You really want to avoid using the wrong size tube where possible. In an emergency situation it might get you home, but there's a high risk of flatting in the process.

Should I carry spare tubes when I'm riding?

Yes, most people will carry one or two spare inner tubes when riding. In the event of a puncture, a replacement tube can be relatively easily swapped out so that you can keep riding.
