Description

XD-15 stainless steel angular contact steering bearings.
Internal steering angular contact bearing with 440C stainless steel balls combined with XD-15 races for lifetime corrosion resistance.
This is the last headset bearing you will install on your bike.
A recent Enduro development, these complete XD-15 bearings are virtually identical in performance and corrosion resistance to our XD-15 ceramic hybrid bearings used for hubs and bottom brackets but lend themselves better to the most abusive steering application.
The mechanical properties of XD-15 stainless steel balls provide a higher level of impact resistance than ceramic balls.
Enduro testing of XD-15 race and ball bearings has been carried out in salt water for months without any corrosion, there is simply nothing on the market that compares.
We are so confident in this material that we guarantee these complete XD-15 headset bearings for life, against corrosion.
The Enduro line of angular contact headset bearings starts with black oxide treated chrome steel rings, progresses to full 440C stainless steel, and the top of the line is, with a lifetime warranty, XD-15 aerospace stainless steel (runs and balls).
They are always designed with the largest balls possible, feature double lip seals mounted in a microgroove (labyrinth), and are 90% filled with high-pressure waterproof grease for maximum protection from sweat and the elements.
Enduro angular contact (A/C) bearings are designed so that all balls are evenly engaged to distribute force over a larger surface area, minimizing wear and maximizing service life.
