    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.

    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.
