I remember, around 85/86, when i first got into the sport, my neighbor had a Cannondale, with the huge, downtube. It always kind of put me off as a buyer, & I never really cared for it much. My question is...when did Cannondale, decide to just make all the tubing on their bikes one size, and stopped using the oversized down tubes? I also remember they were aluminum, and my neighbor was constantly having problems with his frame(he wasnt a big guy, nor was he very rough on his bike), is that way they went smaller?
