In the past couple of weeks I've looked at more first and second generation linear pull brakes and just post Cranks of Death drive trains than I have since they were new. This reinforces my point about how many bikes get put aside for long periods even if they were bought with the best of intentions.
The mix does include older and newer specimens. It's just funny how a big wave will come in from a certain era. A few years ago it was a batch of mountain bikes from the early 1990s whose owners had finished college and were looking for a little nostalgic fun from their teen years. A few of them actually got back into mountain biking that way.
