This is what the dropout looks like on my Charge Duster frame.
It’s got an eccentric BB (it’s a real weirdo, even wears a cravat). I’m not completely opposed to the idea of running SS, but I can’t see - beyond a bodge - how I can fit an RD.
It’s an option, but it snot an easy dropout to replace ATMO. It’s tig welded in and not brazed, so cutting and grinding it out would be hard, and I don’t know how it would effect the metal.
