Avoids the hanging-derailler problem entirely, and is a lot more convenient to shift anyways (shifts while standing still). Only downside is the higher cost.
Yes, an Internal-Gear-Hub would not have the problem deraileurs have. But what about the front deraileur?-The front deraileur relies upon the slack in the chain, and the tension idlers on the rear deraileur, does it not? So Internal-Gear-Hubs are limited to seven or eight speeds, with no front deraileur.
