Those are lovely bikes, but there's no reason you shouldn't ride them rather than have them on a pedestal someplace. They're certainly not dumpster or donation material. I had a 979 I rode for a couple of seasons, it had it's quirks but I kind of miss it now. And a Colnago has always been on my list to own one day.

I remember trying one of the early Roubaix's, having only ridden a vintage Alan for many years. I was amazed at the ride quality and comfort. Your vintage rides still win the beauty contest.
