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

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.
