Raleigh Pros had six gears in the rear as early as 1972. I have a 1972 with 126 spacing and a six speed cluster. The 1972 catalog does not specify a six speed cluster but the 1973 catalog does. BTW, Pro's were the first production bikes equipped with Campy brakes IIRC. Also, most of the early Pro's and Internationals that I've seen from the early 1970's had 172.5 cranks for some reason. If you have a no date pre-1973 crank with 172.5 arms I'd say the odds are better than even it came from a Raleigh.
So when were six speed clusters introduced?
