Wondering if there would be an issue with using another drum with Max Dia201mm. It's from a 1993 Acty The top image is my 1983 Acty which the rear drum is Max Dia 181mm. Thanks. Does anyone know if the tooth count on a 1993 hub is 27teeth?
Possible that the newer is larger diameter. It may work with your brakes still. As for spline count not sure.
