Re:
The one in the photo looks to be from the ‘80s. I have a 1990 Royal with Shimano cantis and triple chainset, seven speed with indexed downtube levers. The frame is 531 ST. I think the earlier ones had double chainsets but I guess that they could be upgraded to a triple. They are excellent bikes, comfortable yet fairly nimble. I use mine as a light tourer/audax/winter trainer and if I didn’t have one already, I’d buy one! Or perhaps a Randoneur.
