FSA Impact PC Integrated Headset

An integrated headset means the bearings sit directly inside the head tube of your bicycle frame, rather than inside separate cups that are pressed into the frame. This design requires a frame specifically built with integrated bearing seats.

Compatibility depends on your frame's head tube standard. You need to verify that your frame is designed for an integrated headset and matches the specific bearing angle and diameter requirements of the FSA Impact PC.

The stack height is the amount of space the headset occupies above and below the head tube. The upper stack height of 7.8 mm and lower stack height of 8.8 mm are specific measurements designed to ensure the proper clearance and alignment between your fork, stem, and frame.

Yes, this headset is commonly used with carbon frames that feature integrated bearing seats. However, always double-check your frame manufacturer's specifications to ensure the bearing dimensions and seat angles match the FSA Impact PC.

Because this is an integrated headset, you do not need a traditional headset press to install cups. You will, however, need a crown race setter to properly seat the crown race onto your fork steerer tube.
