After a bit of research, I (we) have (most likely) decided to purchase 2 Trek 520's. Problem is, in our area, there are no shops that stock them, or any touring bikes for that matter. But after talking with a LBS, we have recieved a good quote to purchase 2 of them. My question is what swap out/upgrades would you make on the 520? They list a 11-32 cassette and 52/42/30 crank in the 2007 model, not sure what the 2006 model had, but it seems to be a big factor in previous posts. What else would you change? Just looking for opinions, and there seems to be alot of them here! Thanks. Anyone out there have a Rocky Mountain Sherpa to weigh in on?
