can anyone tell me which duomatic hub was used on the ccm muscle bikes the model 515 which hade to be screwed out of the hub to take apart or the onethat could be taken apart when the cones were removed this sounds like a job for    duomatic   thanks william rudolph.


Ive never heard of a 515 duomatic two speed kick back hub. My 67 Imperial came with the r102 duomatic. 

goofed it 515 is a 3 speed with a backpedal brake but externaly looks like a duomatic. thanks william rudolph
