I keep obsessing over whether or not to get a newer bike someday for a rather lengthy commute. (like 42+ one way each day ) .. I currently have a Paramount PDG Series 3 with six speed freehub/cassette and a LeTour with 7 speed Suntour Blaze components seeing active duty. I keep repacking and replacing bearings .. replacing chains .. year after year .... just wonder what other people have experienced with how long this old six/seven speed Shimano & SunTour stuff lasts? Forever? Does it ever blow up? I've entertained the idea of upgrading to modern components but, I dunno....
