Heres showing my age.I started collecting bikes in 1970.This was the time when 10 speeds were really invading he U.S. The collectors of that era had the same concerns about the end of balloon tires,krates,etc.Many thought it was the end of bike collecting.The hobby evolved and those who saved the old style bikes saw the prices rise and started collecting the "new" quality 10 speeds of that era.What was quality back then is now considered a classic now.Hang in there and evolve with the hobby.
