Working on this A-D for my sister that I believe is from 77, as that is how the Normandy hubs are marked. Had to go to the co-op as I didn’t have the small 2 prong freewheel tool for the Regina 5 speed on it. Taking off revealed a shim behind the freewheel that abuts the flange on the spoke protector disk. I’ve never seen one and wondered if it was just necessary in this application. Suntour and Shimano freewheels screwed on fine.
It seems that a 6 speed might fit fine on this bike even with 121 rear spacing. I will know in a day or so after new bearings and spoke tightening. Stainless spokes on this bike interestingly. Is that Regina something nice? I don’t have the tool, so I’m not in a hurry to use it.
