I'm thinking about replacing my Trek 7.3fx with this. I love the idea of no derailleur for commuting and those dusty dusty Katy Trail rides! I keep my Surly off of that trail because it is a nightmare to clean that dust out. Anyone know how the internal hub will affect weight? Any experience with the hubs? I had one on my downtube, but didn't keep it long enough to really form an opinion on it.
