If you ask most people, they would probably guess front suspension came first......but they would be wrong. The earliest suspension bikes used rear suspension about 6 years before suspension forks surfaced. The builders often used motorcycles parts. The damping on this bike was actually adjusted by tightening the quick release skewer on the top of the shock! We've added this one to our Descender and Hanebrink SE Shocker which makes for a nice display of the evolution of the design.
