As I mentioned over in the 50+ forum, I often ride with a bunch of 40-to-60-somethings in the local YMCA's MasterFit group. Even when I ride the Bianchi, I almost always have the oldest bike in the group, and of course it's no contest with Capo #1, which turns 50 this year. Most of the others ride contemporary circa 18 lb. carbon or carbon mix bikes, but I am often at or near the lead on the major climbs, particularly on the Bianchi, which is noticeably stiffer than the Capo, having been designed for modern smoothly paved roads instead of Europe's cobblestones, which were still prevalent in the 1950s.
