My last tri gave us TT stickers that wrapped around the tube and the adhesive was to paper. It formed like a sleeve with a handle if you will.

Perhaps you could fab something similar? A "sleeve" of paper (and perhaps a piece of tape to keep it in one place, that comes off easily) could be the mount for your TT sticker. Prevents sticking things directly to the bike.

I still have sticker residue on my lid though...
