However, as much as I am a fan of internals for Recreational riding I have never recommended them for aggressive mountain bike applications. Except for one model, The Rohloff 14 speed internal hub. These hubs are in a completely different league and that goes for price as well, a Rohloff setup usually runs around $1400.
Recently though Shimano has stepped up the game a little, the new Alfine 11 speed hub, although looking similar on the outside to the 7 and 8 that preceded it, are completely re-vamped internally. The 11s are even running an oil bath system just like the Rohloff. A sign that things have changed somewhat is the emergence of some cyclo-x rigs running the new Alfine 11. The hubs are also compatible with the new Gates belt drive setup. It is a bit soon to tell if these hubs have the durability required but initial feedback seems quite positive. We have a couple of projects in the workshop at the moment, which will feature a little later here on the blog, and an Alfine 11 is definitely on the short list as the drive choice.
