Hoping someone can help me as I don't know much about bikes.
I bought a 10 speed bike at a garage sale which the owner said was custom made by a bike maker in St. Louis, MO. She said the frame was chromoly steel. The frame has the name "Behring," which I assume was the builder, and there is a label on the bottom tube which says "Columbus Tubing."
Is anyone familiar with a bike of this description? I have some pictures if that would help.
