Sugino made TA knockoff called Pro Dynamic(5 pin) which had TA
pattern rings and Rene Herse pattern rings. In around 1980 Sugino
also made Pro Dynamic Maxy(5 pin) which had arms and BB of Super
Maxy. This was a little cheaper than Pro Dynamic. Some said in
Japan that Pro Dynamic was more robust than original TA or
Stronglight 49D.
