I don't usually post in touring, but this seemed to be the best place.
I'm moving soon, and need to box all my bikes for moving.

I've watched a few videos and things seem reasonably straight-forward, but I had a few questions?

1) What do you use to protect the cranks/chainrings?
I've just got an empty bike box from the store and don't really want the bike resting on the chainring, what's good to place under the bottom-bracket and how do you prop it there?

2) Alternatives to wheel caps?

3) Protection for drop-outs?
I don't have the bike shop plastic things, what else works.

Thanks in advance.
