  • Does anyone know of a disc wheel valve adaptor shallower than the Zipp/Silca press-on like this?:

    I've just got a disc wheel with a very small hole and even this one is a bit too big, which means I'm losing a lot of air every time I try to take it off. I'm worried I might snap the valve core once I've actually stuck the tyre on.

    Any other options?

  • Valve adapters are meant to be fixed in place with tape on the threads not taken on and off.

    Dremel® time! You can cut pretty big chunks out of most discs (not stuff like Lighweight which have pre-tensioned skins) without weakening them enough to worry about.

    This looks more compact
