Description

The WOLF TOOTH AERO EC44 External Headset is designed for frames compatible with semi-internal cable routing below the stem. Developed for EC44 headsets, it combines an Aero profile with a very low stack height to offer neat integration while retaining the simplicity of standard 1"1/8 stems and spacers.

Machined in the United States from aeronautical 6061 aluminium, this headset stands out for its lightness and durability. Its exclusive Triple-Sealed Weatherproofing system effectively protects the bearings against water and contaminants. The Enduro stainless steel bearings, lubricated with waterproof high-pressure grease, maximise longevity and minimise maintenance requirements.

Designed for modern builds, it features six cable ports and a specific seal at the entry points to prevent any ingress. Supplied as a complete set (upper and lower cup), it benefits from Wolf Tooth's Right to Repair programme and a lifetime warranty on Enduro bearings.

Why choose an EC44 Aero model over a standard one? If you have a high-quality frame (steel or titanium) and want a modern look without cables "hanging" in front of the head tube, this model is the only reliable technical solution for routing cables neatly inside.

Is it compatible with straight headtube frames? It is designed for head tubes with a 44 mm internal diameter. To fit a tapered fork into this type of head tube, the lower cup must be of the external type (EC44).

Is stainless steel really necessary? Yes, because the cables passing through the headset can promote moisture ingress. Stainless steel bearings are the only guarantee that your steering will remain smooth and free of "stiff spots" after a wet or intensive season.

Can I install it myself? Cup installation requires a specific cup press. For cable routing, knowledge of mechanics is required, although the semi-internal system is much simpler to manage than a fully internal system.

Points forts

Integration Modernisation: Allows traditional frames (44 mm head tube) to benefit from a clean "Aero" cockpit with semi-integrated cable routing.

Enduro Stainless Steel Bearings: Uses premium stainless steel bearings, totally impervious to corrosion caused by moisture or sweat.

Multi-Level Sealing: Fitted with double lip seals and Wolf Tooth marine grease for total protection against the elements.

6061-T6 Machining: Each part is CNC machined in Minneapolis for a perfect fit, eliminating any risk of creaking.

Simplified Maintenance: The semi-internal system allows you to change the stem or handlebar without having to bleed the brakes or disassemble the entire drivetrain.
