Wolf Tooth Premium IS52 Internal Headset for ENVE In-Route System

The Wolf Tooth Premium IS52 Internal Headset for the ENVE allows you to use the ENVE IN-Route System with most IS52 frames (see Compatibility tab for more information). This headset gives you a clean, aero cockpit and keeps cables and brake lines completely out of sight. In addition, it features an ultra-low 3.5 mm upper stack height which results in a smooth transition from cockpit to headset to frame.

Sealing against the elements is also very important on fully integrated bikes and the Wolf Tooth IS52 Internal Headset for ENVE uses their triple-sealed system to protect bearings from the elements. It includes Enduro stainless steel bearings that use the largest possible ball size and are filled with high-pressure waterproof lubricant. Machined from aircraft-grade 6061 aluminum, it is also lightweight at 78 grams for the complete headset.

 

Features

  • Premium Enduro stainless steel bearings.
  • Internal o-ring top cap seal prevents water intrusion around the steerer tube.
  • Custom-molded upper cup lip seal provides additional protection for the upper bearing.
  • Custom molded dual-lip seal on the crown race to protect lower bearing in the toughest conditions.

Compatibility

  • Made for the ENVE IN-Route System and compatible with bikes that use an IS52 upper / lower headset and a 1-1/8” to 1.5” tapered steerer tube
  • Use top cap and split spacers provided with ENVE stems and one-piece cockpits
  • Use the compression plug that comes with your fork
