Typically put a cut-down worn-out chainring in the outer position as a chainguard.

My recent adventure rig setup is 11 speed, 46-30 and 11-40, which is more range than legacy triples, indexes perfectly and is evenly spaced. Triples made sense decades ago when the derailleur technology of the time could not manage large ranges or gear differentials.
