Campagnolo Record track headset for 1 inch threaded forks. These great Campagnolo headsets are for all of you who can not use NJS sized headsets such as Shimano Dura Ace and Hatta. The Campagnolo Record headset will fit frames such as those from ITALY like Cinelli Pista, Colnago, Pinarello and others which use the 26.4mm fork bearing race size and the 30.2mm head tube internal diameter standard (widely referred to as ITALIAN or ITA). This headset is made with the same attention to detail and high quality as all Campagnolo Record items. Silver Anodized. Retainer cup and cone bearings.
