I used to run 7-speed Shimano 13 14-28s on my International using a narrow KMC chain and NR derailleurs with no problem. Cheap and more reliable than the Regina days of yore. Never had a ghost shifting problem with them using barcons or DT levers. I played around with a Taiwanese knockoff of a Wolf Tooth hanger extender and found I could probably support a 30 or 32 tooth low if I wanted one.
