Are you running Campagnolo? Rear derailuer looks vintage Campy. Would be real nice if you had put the old style triangle shaped Campagnolo brakes on it, however those brakes, while they looked good in the day were not the best stopping brakes. Your bike looks awesome! Love the old school downtube shifters too! Classic, even the tire stems look as if they are Schrader valve and not Presta.
