Super Record cranks didn't exist as such. A Super Record chain set was a set of Nuovo Record cranks with cut-away Super Record chain rings and a bottom bracket that had a titanium axle, alloy cups and ran 3/16" ball bearings. Similarly, Super Record brakes were actually Nuovo Record piccolo drop callipers supplied with drilled brake levers and brakes shoes with a black plastic coating on the wheel guides. The hubs will be Nuovo Record - Super Record hubs were made for about 18 months sometime in the mid-1970s and unreliable titanium axles, the rear of which snapped far faster than the standard Campagnolo steel items. Even back then they were so rare that nobody ever saw any.
