The lovely Univega I bought from Mark Poore years ago has the early D/A aero group components, including the "DynaDrive" pedals/cranks (AKA "big-hole"). Does anyone remember when they were offered? Since it is non-indexing and just 6-speed, I'm assuming well before 1980, but "inquiring minds want to know." I've got all the stuff to build it up, and maybe it should be done for Cirque/VA, just for the ornery-ness of a very clean and very understated Japanese bike from that era.
