Hi Does anyone know how to remove a 1st series Edco Competition Bottom bracket. I assume it was made in the late 1970¹s and has a 26mm nut on each side and no lock rings. Turning the nuts in either direction makes no difference to the positioning of the BB shell or axle as far as I can tell. It looks nothing like the later Edco BB on the CR site I have close up pictures if anyone is unsure of what I am describing. Sheldon Brown site has no mention of this model BB Any suggestions gratefully accepted. It is in a 1951 Bianchi Paris Roubaix that I am hoping to restore and it needs to be removed!!
