The FSA Orbit CE Integrated Headset is designed for road and mountain cyclists running a 1-1/8 inch steerer tube in a 46mm outer diameter headtube. It serves as a reliable, precision-engineered steering component that offers Campagnolo-compatible geometry for smooth handling; however, it requires a specific 46mm integrated headtube standard, making it incompatible with frames using press-fit or external cup systems.

No, this headset is strictly designed for 1-1/8 inch straight steerer tubes.
You should look for the TH870 top and bottom replacement bearings.
Yes, the H6119 crown race is included with the headset.
No, this is specifically for 46mm outer diameter integrated headtubes.
The bearings are sealed, but you can periodically wipe them clean and apply a thin layer of grease to the contact surfaces.
The total stack height is 9.4mm, which includes the 8.5mm top cap and the 0.9mm adjustment shim.
The angular contact bearings have likely become contaminated or worn; inspect the TH870 bearings and replace them if necessary.
Remove the fork, clean the internal headtube interface and the bearing seats, apply a fresh layer of bicycle grease, and re-torque the top cap adjustment.
Ensure the 0.9mm adjustment height is correctly seated and check that the top cap is not bottoming out on the steerer tube before removing all play.
Compatibility is strictly limited to 1-1/8 inch steerer tubes and 46mm integrated headtubes. During setup, ensure the frame's headtube is cleaned and lightly greased with a high-quality bicycle-specific bearing grease. When pressing in the crown race, use a dedicated crown race setter to avoid damaging the 7075T6 surface. For maintenance, remove the top cap periodically to inspect the yellow-sealed bearings. If you feel 'notching' in the steering, the TH870 bearings should be replaced to restore factory-smooth rotation.
