Wolf Tooth Premium EC44 Aero Headset for Semi-Internal Routing

Built for riders who prefer the flexibility of semi-internal (under the stem) routing, our Headsets for Semi-Internal Routing were developed for frames using an EC44 headset. These headsets are equipped with a custom seal at the cable entry ports that eliminates contamination from moisture and debris, maximizing bearing life.

Machined from aircraft-grade 6061 aluminum at Wolf Tooth in Minnesota, USA.

Semi-Integration

This Internal headset helps reduce aerodynamic drag by hiding cables away from airflow, while still preserving a more user friendly experience when building up and traveling with your bike. It presents a svelte profile with its ultra-low stack height and narrow, machined profile. Extremely lightweight at only 120g, it sets the benchmark in performance for a semi-integrated cockpits.

Slammed.

These headsets feature an ultra-low 20.1mm upper stack height for a smooth transition from cockpit to headset to frame.

Triple-Sealed Weatherproofing

Sealing against the elements is critical on fully and semi-integrated bikes, where a bearing replacement involves disassembly of the cockpit and a brake bleed.

Like all Wolf Tooth headsets, this new option features our best-in-class triple-sealed system to protect bearings from the elements. It also includes Enduro stainless steel bearings that use the largest possible ball size and are filled with high-pressure waterproof lubricant. 

Machined In-House

Machined and assembled right here in Minnesota, USA. Our new Premium EC44 Aero Headsets for Semi-Internal Routing are covered by our Right to Repair program that offers individual replacement parts and service guides.

Wolf Tooth Premium Headsets carry a lifetime warranty.
