On road bikes you'll frequently see barrel adjusters mounted on those bosses for the derailleurs, but what to do if it's "just" a ss/fg conversion? I've been wondering about a solution for awhile now (other than just leaving them as is), so it's time to ask the masses. Maybe someone knows of some random product or has come up with something at home that proved itself useful. They're a bit unsightly just sticking out so if they can be put to some functional use that'd be fantabulous.
Non-destructive solutions, please.
