When did new bikes stop being sold with 27" tires? Early 80's? It's amazing to me that there are enough 30 year old bikes on the road wearing out rubber that factories are still cranking out 27" tires in production volumes.

It indicates the lasting impact of the bike boom.

Tuesday night on my commute home I encountered only two other bikes, both from the 70's. Including mine, that made 100% C&V iron. I guess when the going gets tough, only the tough remain going.
