This has gotten a little out of hand... IGH's and derailleurs require maintenance and are subject to destruction due to the winter elements. Plain and simple. Going SS will make your bike ALOT more reliable in the long run while requiring ALOT less maintenance. You still must clean and lube the chain, clean sprocket, repack bearings, etc. You will not however have to adjust the derailleurs due to cable stretching etc. You will not have to clean and lube the derailleurs to get all the sand and road salt off. You will also not have those parts to break on you during your commute. IMO, Its a great conversion if your body and commute are willing.
