Those 3-arm cranks are sweet. When did Campagnolo start making them? What are they called?
I believe they are actually Dia-Compe ENE. Kyle Brooks posted about the Bianchi prototype in his Retrogrouch blog back in June:
The Retrogrouch: Bianchi L'Eroica Bike
It seems the brakes, shifters, crank, and possibly stem are Dia-Compe products.
