Same here. Bought a run down bike for 50 € for use in the city (it looked so worn down nobody with a sane mind would think about stealing it) and then found out that it was a travel bike (Campus Voyager III). A few years later I had to replace the wheels (the flanks of the rims got too thin) and still use it sometimes. It's absolutely silent and nice to drive.I purchased a 2nd hand mtn bike at a yard sale that was plastered up worse than that one. Layers on layers. Wanted it for something cheap to use where I worked. Something I could just throw in the back of my truck and not worry about too much. I was very surprised it rode so well for a $20 bike. When I pulled a few stickers it turned out to be one of the early high end Trek's with a True Temper S3 frame.
