Features:

• Premium Headsets 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 44 mm 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
