Original Cane Creek headset for IS42 frames (41.8mm bearings). This 'tall' version has a 15mm stack height which is shorter than many of the original Cannondale headsets. Designed for 1 1/8" straight steer tubes.
Kit includes two IS42 bearings, one crown race with integrated seal, one upper wedge/seal with alloy cap, and a star nut with bolt and top cap.
This high quality headset is a great replacement for Cannondale's KB002/ headset found on many road bikes over the years.
