Speaking of unusual cranks like PMP, does anyone remember the FB variable geometry crank which had a sliding crank within a crank to provide different crank lengths at different points in the crank rotation? It was shown at the Milan show in the late 1970's at the Mairag booth but was the design of Fontennaz and Berclaz.

Just one of the reasons to go to bike shows is to see the offbeat ideas that someone has made the effort to put into prototype form!
