Recently my wife and I arrived at the top dead-end of a canyon climb and got off to take a drink. There were two cyclists there on mid-level recent race bikes who were explaining how to choose a bicycle to two motocyclists who were apparently curious.
The racer cyclist pointed to our bikes as we rode up, mine that day an early 70s English race bike, hers an early 80s Batavus Professional, and was saying loudly to the Harley riders:
"Now look at these two bikes, they might be as old as ten years ago and they weigh between 35 and 40 pounds which was lightweight back then."
