^^ pretty much just track frames. But then you'd have another sticky wicket trying to hack a RD hanger on. Take note, the OP has said nothing about cable stops.


If you have calipers, measure the OD of your downtube. If you don't have calipers, find someone that does and have them measure the OD of the downtube. Then get to googlin' and find a clam on pair of DT shift bosses. Pretty much your only option unless you want to monitor the area like a hawk looking for cracks.
