FSA Orbit C-CX Integrated Headset This FSA Orbit C-CX Integrated Headset won't make much sense on anything but a cyclocross bike, with that integrated cable hanger. But for CX, it's stellar. It's a Hiddenset design, with an integrated 42.0mm OD, 45 degree bearing. Yeah, basically the regular FSA Orbit with the hangar for your cyclocross canti brakes.
