I think I may be at fault for Doug Van Cleve's Vitus, since that I'm pretty sure that was the Campagnolo Donor Bicycle that I eventually parted out.
Before I took the bike apart I rode it some and it felt ok, but slightly "noodly" out of the saddle, up a hill, much different than my experience with modern tigged aluminum and oversize tubing. I'm no lightweight and I was in the big ring so I was kinda pushing the bike. Interestingly enough I found the ride much more forgiving than a modern aluminum bike. I'm not sure if that is due to the smaller tubing or the bonded construction, but I suspect this is why people really like 'em.
It was *real* light though!
