I have just bought a Proflex 550 without any wheels. My 'new' frame has a gripshift with only a 6 speed rear changer. Does anyone know or can anyone remember what speed rear cassette was fitted to the 550 as standard. I'm a bit old now and even though I owned one back in the day I can't remember what speed the rear bloc was.
Thanks in advance for any replies.
