In stores, as a regular customer, you will never...and I mean never, get a detailed answer from a salesperson. For lots of diff reasons. What you will get is, "sure this bike would be fine for touring", or "absolutely the gearing is so low on this bike you can pull tree-stumps", and while I am being cynical, this is nearly always from someone who has never toured, or is young, and or young and strong, and only rides very light bikes very fast, or wouldnt want to appear wimpy gearing wise.
Cynical, I know, but ....
Yup.
Before I got into touring the only off-the-shelf-production touring bikes I could look at in stores was the Trek 520 and a Fuji. I wanted steel, did not go into a Cannondale store.
One sales person told me that the bike I REALLY needed to get was one that he then showed me how great it was because it had extremely short chainstays. Yup, he said I wanted short chainstays for touring. I knew better and promptly walked out.
Now if you go in a store that sells camping gear and bikes, at least there is a chance that the sales staff might know someone that does touring if they have not done any themselves. But they still are only selling their brands.
