“The new Wolf Tooth Premium Internal EC44 Headset for the ENVE IN-Route System was developed to meet the needs of framebuilders using the ENVE IN-Route System of cable integration and cyclists who want a clean, aero headset solution. The Wolf Tooth internal headset profile contributes to aerodynamics by hiding cables from airflow, has a short stack height, and is extremely lightweight. Wolf Tooth headsets are machined with aircraft-grade 6061 aluminum at Wolf Tooth in Minnesota, USA.” – Wolf Tooth Components

“The new Premium Internal Headset features an ultra-low stack height (15.8mm) top cap for a smooth transition from cockpit to headset to frame. This is the shortest stack height of all internal EC headset for the ENVE IN-Route System, and among the shortest for any internal EC headset for any fully integrated cockpit on the market. The new headset is also incredibly lightweight at only 116g for an upper/lower pairing.”
“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 the 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. The bearings also have a dual-lip seal system for an added layer of protection.”
