I'm just about to put a nice Trek 780 touring bike with step-through 18" frame up for sale. It's not quite a mixte, although a similar frame design just without twin lateral tubes. I got it for my wife and built it up as a touring bike with nice components. What's a 780, you ask? It's the European version of the 720 hybrid bike and has chrome-moly tubing. It has rear rack braze-ons, lowrider braze-ons on the fork, and other nice touches. Almost new touring wheels with Shimano LX hubs, etc. I can't recall if it's a 8 or 9 speed at the moment, but if it's an 8 speed it could easily be converted into a 9 speed rear (the freehub will take 8-9-10). PM me for more details if you are interested. I'm in the Philadelphia area, but am willing to ship. Probably looking in the $475 price range. The wheels cost me $200 alone and they are almost new.
