take it... Randonneur was a Columbus Cromor frame build at a bike shop. The frame is better than your alloy frame and has Canti bosses, a rear rack boss and plenty of eyelets for fenders and racks. Look at the components (because those are bike store built). Your Trek has 600 or 105 index (I cannot remember) make sure that this is up to par (it is a pre index bike). Still the frame is a good deal compared to the Trek.
