I just received my BB and discovered it has this rubber pad on the bottom, with a label too, which I don’t like since it works poorly with Velcro.
If you can accept modifying the pedal you can flip the bottom lid - probably a known trick for most of you but maybe some pictures are still interesting to those who haven’t considered doing it.
Drill a new hole as a mirror image of the existing one. Countersink the new hole and the two at the other end for a flat surface.
Trim off a little rubber to allow the lid to sit flat.
Reattach the lid with the rubber now inside the pedal, add Velcro. Done!
