I'm 50. Never quit riding or wrenching since the early 70s, but haven't had a major bike upgrade in 25 years. Just keep riding the Columbus steel frame and replacing those chains and freewheels. Downtube friction shifters still do the job! And a 22 lb bike is still pretty decent. But I do need a new headset now. Maybe I'll splurge on a new frame one of these years and enter the modern era (freehub, cassette, more than 12 speeds, STI shifters, threadless headset). I do lament the demise of certain favorite components, like the Regina Oro chain and freewheel. And I can't find Campy grease anymore (but Pedro's is just as good).
