These are Campagnolo super record non fluted cranks, 172.5mm in length with 52/42 rings. They have dust caps / crank bolts. Bottom bracket is Italian threaded with a titanium 108mm spindle (not sure on the bb make). These were part of a private collection. They have 21/11 numbers on them. These might show minimal wear from display. Box shows wear and the plastic inside is breaking from age.
