I have an old Trek 720 Multitrack from 1990 or so. It's basically a steel mixte. It was off the road and on a trainer for a few years. Last year I took it to the LBS and he put some new, but basic, components on it to see if I still liked it. Well, it's still a fun bike. I have another straight bar bike with Tiagra components and I'm thinking about swapping everything out and putting the nice components on the old bike. Would this be a waste of money? Is it even possible? I love the idea of having a good old solid bike.
My other idea is to buy a Jamis Coda Sport and maybe still swap out the components. And then I'd have yet another bike.
