Found this site while searching for repair advice. Very interesting site. Been riding off and on for many years. Since retiring, decided to get more serious about riding-exercise! Riding my old 10 speed Puch from the early 80s. Spend winters(3mos) in Sarasota, Fl., where this last winter I rode about 600 mi., great flat riding. Longest continous ride so far is 50 mi., hope to make it a lot longer before the summer is over.
