I want to do some long distance touring on this bike, but I wanted your opinions about it. It is a Trek 400 from the 1980's. It has 12 speeds. The frame and fork are both cro-moly. The tires are 700 x 25, but I think my rims could support 700 x 27. It is lightweight and only weighs about 23 or 24 pounds. I would be using front and rear panniers. I know the chainstay length wouldn't be a problem because I have ridden the bike with rear panniers before.
