I've bought a Gazelle Trim Trophy (see Catch of the Day) a few weeks ago. I know it's a good bike, and that I got a bargain at $50, but I'd like to know more about it. It's 531, with nice lugs, Shimano 105 rear mech, Shimano Exage 300 Ex at the front. Weinmann centrepulls, but with aero levers which I'm sure aren't original. 700 x 20 wheels (eek!). It's all in good nick, but could do with a clean. The number on the BB is 3299051. Can anyone help me with age and approx value, and anything else interesting (where did it fit in the range etc)? Pics on the link below, and thanks in advance......
