There is a complete Sugino 75 road group, which was created to celebrate Sugino's 75 year anniversary in 1985. the derailleurs were based on the Suntour Superbe Pro line and manufactured by Maeda for Sugino. I believe Sugino, in turn, used to manufacture SSP cranks for Suntour. Both were members of the JEX trade group.

The group consists of cranks, FD & RD, brake calipers, carbon levers, carbon DT shifters, carbon clipless pedals, and the aluminum honeycomb Tyranno disc wheel. Although, I'm not sure if the carbon stuff dates from the same time as the rest of the group set.

high quality stuff and infuriatingly rare.
