A well-known flipper in my area (really two, Old Fat Guy and RedXJ) found that students value the looks and reliebility of well-assembled Schwinns, Raleighs, and other classics as utility bikes. The demand enables pricing of several hundred for well-rebuilt transportation from these two. That hasn't really translated IMO into a very different market in Ann Arbor for the collectibles and high-value '80s/'90s midrange steel bikes, as far as I can tell.
I do imagine that collectors will have less disposable income for a while to come. I don't see buying a "new" classic until I sell a few. I doubt that classic Masi- and DeRosa-based bikes will become substitutes for a good Raleigh Sport, to commute back and forth to class.
I am worried that soft-riding classics like early PX-10s will all become drewed and irreversibly fixed. Maybe we need a "Save the PX-10s" movement.
