Favorite bike?
Easy. I only had one bike for 42 years. It was a PX10, bought new in 1971. I rode it for recreation, to college, to work, touring to San Francisco, to Mexico, to Oklahoma ... and even competed with it a few times. It had four wheel sets - 2 clincher, 2 tubular. And I don't know how many component changes. Had a Phil Wood BB that lasted for decades! Maintained everything myself, including one complete paint job. The original Ideale saddle was still functional. I had a perverse feeling for that bike. My favorite by far.
But not my best. That would be my current road bike, a 1992 Paramount PDG 7. The ride is marginally better than the Peugeot, and so are the components. Other than the Phil Woods BB of course.
