Product Information

Full details

This product guide is for road and hybrid cyclists using 700c wheels, providing a reliable pack of five inner tubes. The key benefit is ensuring you have spares readily available for common tire sizes (18c-25c) with a long 80mm Presta valve for easier inflation on deeper rims. A potential caveat is that these tubes are specifically for 700c wheels and may not fit other wheel diameters.

Can I use these tubes with a Schrader pump?

Yes, but you will need a Presta-to-Schrader adapter to connect a Schrader pump to the Presta valve.

Are these tubes suitable for mountain bikes?

No, these tubes are specifically for 700c road and hybrid bike wheels and tire sizes. They are not compatible with mountain bike wheel or tire dimensions.

How many inner tubes are included in this pack?

This pack contains five (5) inner tubes.

What does '700c' refer to?

'700c' is a standard wheel size used for road bikes and many hybrid bikes. It indicates the approximate diameter of the wheel.

Troubleshooting

Tube won't hold air after installation

Ensure the tube is not pinched between the tire and rim. Check for small tears or punctures along the tube. Verify the valve is properly seated and not damaged.

Difficulty installing tire onto rim

Ensure the tube is only slightly inflated. Work the tire bead onto the rim gradually, starting opposite the valve. Use tire levers carefully if necessary, avoiding pinching the tube.

Valve stem leaks air

Check if the valve core is tightened properly. If the valve itself is damaged, the tube will need to be replaced.
