I've heard that internal gear hubs are less efficient than derailleurs. ?? But there are a lot of pluses for internal gear belt drive. I'm not gonna be the one to tell Co-motion and such that they are doing something wrong.
A rohloff hub is nearly as efficient as derailleur systems. Sometimes even more efficient due to the extreme chainlines today's derailleur systems see.
