Wolf Tooth Premium EC44 Internal Aero Headset for ENVE IN-Route System
Wolf Tooth Premium Internal EC44 Headsets were developed for frames using the ENVE IN-Route System of cable integration with a 44mm head tube. It was made for cyclists who want a clean, aero cockpit that keeps cables and brake lines out of sight. Wolf Tooth headsets are machined with aircraft-grade 6061 aluminum at Wolf Tooth in Minnesota, USA.
Full Integration
This Internal headset helps reduce aerodynamic drag by hiding cables away from airflow, and presents a svelte profile with its ultra-low stack height and narrow, machined profile. Extremely lightweight at only 116g, it sets the benchmark in performance for a fully integrated cockpit.
Slammed.
The new Premium Internal Headset features an ultra-low 15.8mm upper stack height for a smooth transition from cockpit to headset to frame. This is the shortest stack height of any internal EC headset on the market.
Triple-Sealed Weatherproofing
Sealing against the elements is critical on fully integrated bikes, where a bearing replacement involves disassembly of the entire 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 in Minnesota, USA
