Managed to navigate the confusing multiple systems for describing tyre size, and ordered these. The tube is labelled much as the original tube was, and appears to be of good quality. Diameter is perfect. but cross sectional area is much smaller than the old tube. I assume that the old tube has stretched over the years and installed the new one. Early days, but the tyre is fully inflated a week later.

Good quality. Does the job well.

It was ok

Good quality inner tubes and easy to fit to bike

Arrived on time item as described

Great seem to do the iob

The delivery was quick, arrived by the expected time, next day. The size described for the inner tube was the exact size I needed for my bike. No problems encountered, would order again from this seller.

Ordered 28” tubes we’re 29” Tight squeeze getting them in.

Good to be able to choose exact size and valve type online. Tubes delivered to my door.

Très bonnes chambres à air, remarquablement plus épaisses que les autres du marché. La taille correspond bien, RAS.

Alles bestens

Now that's a bike tube. Be sure you get the correct valve type for your bike
