1982 Specialized Stumpjumper

The Stumpjumper was generally considered the first "production" mountain bike. We are trying to get a list of bikes on the Specialized history page to compare specs and serial numbers so we can determine the chronology of the models. This bike is a very clean original bike including seat and tires. Since there were not mountain bike specific parts yet you see the use of some French touring parts (brakes and cranks), Japanese parts (hubs, shifters/derailleurs), motorcycle sourced brake levers, BMX stem and pedals......must have been a nightmare to put together these early bikes with parts from so many different sources.
