Product Information

Full details

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.

Extended Product Information

FAQs

Does this headset work with tapered forks?

No, this headset is strictly designed for 1-1/8 inch straight steerer tubes.

What replacement bearings should I buy?

You should look for the TH870 top and bottom replacement bearings.

Is the crown race included?

Yes, the H6119 crown race is included with the headset.

Can I use this on a 44mm headtube?

No, this is specifically for 46mm outer diameter integrated headtubes.

How do I maintain the bearings?

The bearings are sealed, but you can periodically wipe them clean and apply a thin layer of grease to the contact surfaces.

What is the total stack height?

The total stack height is 9.4mm, which includes the 8.5mm top cap and the 0.9mm adjustment shim.

Troubleshooting

Headset feels 'notchy' or gritty when turning the bars

The angular contact bearings have likely become contaminated or worn; inspect the TH870 bearings and replace them if necessary.

Creaking noise coming from the headtube area

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.

Play in the headset even after tightening

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.

Pros and Cons

Pros

Durable 7075T6 crown race material
Easy to source spare parts like TH870 bearings
Smooth steering due to 45x45 angular contact design
Standardized compatibility with common Campagnolo-style frames

Cons

Not compatible with 44mm or tapered headtubes
Requires professional tools for proper installation
Specific 46mm headtube requirement limits frame options

Setup, Compatibility & Care

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.
