    "Grub screw"

    Any idea what the "grub screw" does on the spring cage cover of a Campy Nuovo Record derailleur? I can't make heads or tails of it. Got the name from the 1974 catalog description.

    I think it's a "set screw" in the U.S. A set screw is usually a headless screw that threads into an assembly in such a way that it retains it in position or adjustment.

    Ok thanks. I get it now. The one on the Nuovo Record spring cage cover serves as a stop to the rearward movement of the pulley cages. So it does not adjust.

    Any hardware store, Home Depot or Lowes has them. Just look in the drawer marked "set screws" and pick the right diameter and length. Most places even have them in metric sizes.

    Exactly right. But expect a blank look if you ask for "grub screws" in the US Midwest.
