I've got a 1989 Trek 1500 that's dieing. I'm looking for a frame to put all my components on. There's a '85 Eddie Merckx corsa on ebay and I'm wondering if that would be a good match for the 600/ultegra stuff on my bike. Would this be really heavy? I have picked up steel bikes that were lighter than my aluminum 1500 but those were modern frames and parts. I like to pretend I'm fast and don't want a boat anchor.
