Ahead-headset building classes: Ahead-headsets are divided into the "classical" building class, the semi integrated "Press Fit" and the full integrated "Drop In" headsets. The "classical" version has a bearing which is located outside the steerer tube. "Press Fit" and "Drop In" headset bearings are located inside the steerer tube which results in a lower stack height. In contrast to "Press Fit" headsets "Drop In" headsets don't have to be pressed in. The bearing rests directly on the angled (36° or 45°) surface of the steerer tube. The most common "Drop In" versions are called "Drop In Campy" for Campagnolo Hiddensets and "Cane Creek" . For more detailed information please contact our service team. The FSA configurator easyHeadset makes it easier to choose the right headset.
