Hello folks...new to the forum and new (this summer) to cycling. I was just given a Raleigh Gran Sport that I think is from the 70's. It is the biggest frame I've ever seen on a bike (The seat tube is 27" or 28" - not sure exactly where to measure). It is light blue, with Gran Sport in green on the downtube. I've been researching, but all I've seen are ten speeds. This is a 12 speed, with shifts on the downtube. Any ideas how I might determine what year it is? Thanks...
