That should'nt happen obviously, but the chain hangs on the chainstay when you remove the rear wheel. If you do this alot to flip the wheel. Its probably nice to have the protector (guessing).
Good guess! I couldn't see why my frame came with one until I had the wheel out a few times. Still plenty chipped near the BB though. I need to tape that shit up.
