Designed exclusively for ENVE’s IN-Route internal cable system, this headset delivers an ultra-low stack profile while maintaining the smooth, reliable performance expected from a premium, USA-made component.\u003c\/p\u003e\n\n\u003cp\u003eMachined in Minnesota from aircraft-grade 6061 aluminum, the EC44 headset is built to complement modern aero frames and one-piece cockpits without unnecessary bulk or weight. Wolf Tooth’s focus here is refinement—tight tolerances, thoughtful sealing, and a finish that looks just as good as it performs. Available in multiple anodized color options, it’s an easy way to add subtle customization while keeping everything functionally dialed.\u003c\/p\u003e\n\n\u003cp\u003eAt the core of the system are Enduro stainless steel bearings, chosen for their smooth rotation and resistance to corrosion. These bearings are protected by Wolf Tooth’s industry-leading triple-seal system, designed to keep out water, grit, and road grime in all conditions. The result is longer bearing life, quieter operation, and consistent steering feel over thousands of miles.\u003c\/p\u003e\n\n\u003ch3\u003eSpecs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC-machined 6061 aluminum.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e Premium Enduro stainless steel bearings with lifetime warranty.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpper Stack Height:\u003c\/strong\u003e 15.8mm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLower Stack Height:\u003c\/strong\u003e 12.25mm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Weight:\u003c\/strong\u003e 116g (69g upper, 47g lower).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBevel Angle:\u003c\/strong\u003e 36 x 45 degrees.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility \u0026amp; Design Details\u003c\/h3\u003e\n\u003cul class=\"design_benifits\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Fits only the ENVE IN-Route System.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeadtube:\u003c\/strong\u003e 44mm internal diameter straight headtube.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteerer:\u003c\/strong\u003e 1-1\/8” to 1.5” tapered steerer tube.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegration:\u003c\/strong\u003e Designed for use with ENVE stems and one-piece cockpits using ENVE-provided top cap and split spacers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealing:\u003c\/strong\u003e Triple-sealed design including an internal o-ring top cap seal, molded upper cup lip seal, and dual-lip crown race seal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Complete upper and lower EC44 headset, Enduro bearings, and two 0.5mm spacers for fine-tuning compression.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThis EC44 Internal Aero Headset is a purpose-built solution for ENVE IN-Route frames, offering clean aesthetics, low stack height, and exceptional durability.
