If you want to lighten that bike, I would suggest you start by finding a new frame. Those Continentals were some of the heaviest "lightweight bikes" made. There are a lot of vintage steel frames out there that can be built up to be under 20 lbs. My Hetchins weighs about 2 lbs. more than my Trek 5000. I imagine if I were to swap out all the components, the Hetchins would be lighter than the Trek. Heck, if I were to just trade the Brooks saddle for the Aliante, they would be close.
