  1. No, these are speed holes. They make the bike go faster, plugging them will instantly make the bike stop.

    Of course you can mount one.

    I have a cage on that down tube with a small spacer (1mm at most) and tightened just under the 2nm. Used a cage with flat mount vs curved mount to accommodate the grail’s flat down tube.
