When we got the Co-Habitant's Surly Cross-Check frame, it was supposed to be an off-road-capable supplement to his vintage roadbike, not a replacement. But after he built up the Surly and took it on several rides, the old Motobecane was soon put away. We had expected that the modern cross bike with wide tires would be more comfortable, but slower and less agile than the vintage roadbike. Instead, it is more comfortable in addition to being just as agile and also faster - not to mention more stable and entirely lacking in shimmy on descents.
The Co-Habitant is a wee bit disillusioned in vintage bikes at the moment. All the lugs and "patina" in the world are not worth it to him, if a reasonably priced, good quality new TIG-welded frame fitted with decent components offers a better ride. That is not to say that a mass produced mid-tier Motobecane from 1976 represents all vintage bikes. But sometimes experimenting with vintage until you find a good frame can be more expensive than buying new.
We've considered turning the Motobecane into a beater city bike, but that idea was eventually dismissed. Ultimately, he likes wide tires and stable handling for city riding, and a twitchy 1970s French roadbike is just not his idea of a good time in our pothole-ridden neighbourhood. Fair enough.
So, what to do with a retired bike? One option is to sell it as a complete bicycle. The other option is to strip all the good components, keep them for future projects or trades, and sell just the frame. In the past, we've always gone with the former, even though financially it makes less sense. This time we are considering the latter, but ultimately still leaning toward the former out of sheer sentimentality - if Myles is kept intact, at least he would still be "alive." But of course that's ridiculous.
low bottom bracket issue I've now actually experienced pedal strike on this bike and that's enough to convince me that I need a fixed-gear specific road frame. In the case of the Moser, I plan to move its wheelset and some of the other components to the new frame when I get it, and just hang on to the Moser frame as a keepsake. I got in in Austria and the memories associated with it are worth more to me than whatever money I could get for the frame. Maybe some time later I will give it away to a friend as a gift, but I just don't feel that it's sellable.
What do you do with bicycles that you replace or retire? Does sentimental attachment get in the way of reason?
