Curious as to what chainrings came on those owned by members. Seems like 52/44 NR rings are correct. My 74 catalog does not specify, but the Team Pro is listed as having 52/42 SR rings. On "Retro Raleigh's" a ' 72 is described as having a 52/44, and a ' 73 having 52/43.
Side note-Raleigh trivia: The Professional shown in the catalog has the front brake cable improperly installed, front lever is hanging loose like the cable end wasn't engaged. Hmmm............
