Specialized Aethos Headset

No, this specific headset kit is engineered exclusively for the Specialized Aethos frame. It is not a universal part, so please verify your frame model before purchasing to ensure the bearing dimensions and stack height match your bike's requirements.

Yes, it comes with the essential components for a complete overhaul, including the upper and lower bearings, compression ring, a 45mm carbon cone cover, and five carbon spacers. You will only need your existing fork and stem assembly to complete the installation.

Yes, the kit features high-quality sealed bearings. These are designed to keep contaminants like grit and moisture out of the race, which helps maintain smooth, responsive steering over the long term.

This headset is designed to work with the factory-spec Aethos fork geometry. If you are installing an aftermarket fork, you must ensure the steerer tube diameter and crown race seat match these bearing specifications exactly; otherwise, the fit may be compromised.

The included carbon cone cover is specifically shaped to integrate seamlessly with the Aethos head tube profile. Using the factory-spec cover ensures the correct stack height and maintains the bike's intended aerodynamic and aesthetic lines.
