My '91 Bottechia is the newest bike I own. I usually ride between 50-100 miles a week, split up between the Bottechia, my '84 LeTour and my '81 WorldSport.
There's a group ride that does about 35 miles averaging 15 mph that starts near my house, I've been thinking about checking it out. Apparently its a big mix of older experienced riders and novices--sounds like it could be fun.
