I’ve taken out the old tube which measures 700x35 45c but I could only find 700cx35 38. Will this fit ok? Many thanks

    How did you "measure" the old tube. (Hint: Check the side of the tire for measurements.) Commented Aug 10, 2022 at 13:40

    Does this answer your question? Can I use an inner tube that's too narrow for the tyre?

    What do you mean by "700x35 45c"? You should measure the diameter of your tire instead of the tube. Then you go find a tube that has your tire width in that range. Lets say you have a 38c tire, you could use one that's meant for 35-42c.
