I am nostalgic as the next guy. I'm 64 and wish I still had my old Peugeot PX10. I'd buy back the Colnago in a minute and then upgrade it. Maybe turn it into a fixed gear bike - they are GREAT riding. I have a fixed steel bike that I love to ride. If not, I just bought a new carbon frame - the rs2 group buy from the forum- and built up the bike. 16 lbs. I have been a steel guy, with one cannondale exception, and I tell you what, the rs2 rides like a dream! You can get a lot of bike for $1600-2000 these days. It's good advice to look at the Giants. If I were you I'd look at Cannondale too. Their aluminum rides great. The main thing is that it fits you and you like it. Let us know what you end up doing. The main thing is to get something you will ride.
