I’ve been on 2 wheels for most of my life. The first “real” bike I can remember was a Schwinn Stingray, blue over silver with a banana seat and a coaster brake. Not only did I ride that bike as much as I could it also got me started with mods and tinkering. Changed the seat, handlebars, grips, chain, you name it. I was hooked.
My next bike after that was a “grown-up” 10 speed… except that it was yellow and it was from Sears. So as you can guess it didn’t have the best components on it and I destroyed several rear derailleurs in short order, twigs and mud can really do a number on them, especially when they are made of cheap plastic. I was a man ahead of my time… I was riding that bike like I was a CX racer long before I ever even heard about CX.
