Trying to get a year and value on this bike. I believe it's a 54cm frame, shimano Exage motion drivetrain in said to be rideable and good condition other than some play in the rear wheel. Would this be worth the asking price? I was thinking in the $25-$40 less range but I'm not great at pricing. 54 may fit, 56 would be ideal. I plan on adding a rack (if the dropouts allow for it) and panniers and keeping it...but if it doesn't fit and I chose to resell after a thorough cleaning and greasing, what would be the expected value?
