Wolf-Tooth headsets are manufactured in the USA from 6061 aircraft-grade aluminium and are available in two series, Premium and Performance, which differ in terms of bearing materials.

Wolf Tooth Premium bearings:

The Premium series, featuring stainless steel bearings, is designed for maximum durability and smooth operation. Multiple layers of specially shaped double-lip seals protect the bearings even under the harshest conditions. This makes them lightweight, strong and extremely durable.

ENVE IN-Route cable routing:

Hidden cables and wires are essential when it comes to modern bicycles and aerodynamic advantages in competition. As a complete system, ENVE IN-Route offers a variety of stem, handlebar, headset and fork combinations to provide the right fit for every frame material and rider size. It routes all shift and brake cables through the stem, then through the headset, and aligns them in front of the steerer tube. From there, the front brake cable enters a connection at the front of the steerer tube to be routed through the left fork leg to the brake. The rest flows around the steerer tube into the down tube. These features make IN-Route a complete solution for cable integration.

IN-Route works by routing brake lines and cables through the handlebars, into the stem and down into the front section of the head tube. This is achieved by using a fork with a round 1.125-inch steerer tube and routing the hoses/cables between the steerer tube and the larger 1.5-inch upper headset bearing. The upper bearing cap and spacers match the shape of the IN-Route stem and the SES AR One-Piece handlebar from ENVE.
