General Information
The Dynamic Professional was Sugino's copy of the classic French TA Pro 5 Vis / Stronglight 49D crankset popular with cyclotourists and randonneurs. Sharing the same distinctive 50.4 bolt circle diameter as its French ancestors, it can often be found mated to both French made rings as well as Sugino rings.  The Sugino chainrings, however, incorporate a different BCD for the inner chainrings.  Early on, the design of the Sugino chainrings was similar to their lower-end DJX-1 model, but were later changed to a design similar in appearance to the famous Rene Herse cranks.  At least three variants of the Sugino Dynamic Professional chainring are known to exist.

The Dynamic Professional was originally issued as a cottered crankset, and was upgraded to a cotterless design in the early 1970's.  It was replaced by the Sugino PX in the early 1980's.  Below is a page from the 1973 Sugino catalog, showing the Dynamic Professional crankset.  A later 1978 catalog refers to the same crankset as the "Pro-D".
