I own a bicycle, presumed 1980's, it is badged as Steyr-Daimler-Puch and also Made in Austria. I is labelled as EVEREST, but I can find no other info on the web. It has a triple chain set, giving 15 gears. Road bike with dropped handlebars and weinmann 700c wheels and brake components, reynolds 501 frame. I would like as much ifo as possible on this model, anyone ableo help, thanks
