On the small-small the derailleur cage folds back on the derailleur until the chain sags.

benefit to small/small sizing is you get max amount of chain, so fewer issues if the big/big is a bit tight......I know from personal experience (fall and go boom....but at least is was slow and only hurt my ego)
