Enduro Headset Bearing 1.5" XD-15 Stainless ACB 68

ACB 6808 CC SXD 1-1/2" XD-15 Angular Contact Headset bearing (40mm x 52mm x 6.5mm; 36 x 45deg)

Angular contact Bearing for Internal Headset featuring 440C stainless steel balls paired with XD-15 races to provide lifetime corrosion resistance.

This is the last headset bearing you will ever install into your bike.
A recent Enduro development, these full 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 more abusive application of the headset. The mechanical properties of stainless steel balls provide a level of impact resistance superior to ceramic balls for headset application. Enduro testing of bearings with XD15 races have been run 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 full XD-15 headset bearings for life, against corrosion.

This size bearing is also known in the bike Industry by these part numbers:
HD 1404K
BAA0006K
MR-127
MR-196
MH-P25K
BAA1132

The Enduro line of headset bearings consists of two basic performance levels that are a substantial step up from standard bike industry specifications. Enduro "entry-level" headset bearings feature premium materials like Black-Oxide treated races and carry a two year warranty, while our premium 440C stainless headset bearings carry a full lifetime warranty. 

All Enduro bearings are always engineered with the largest balls possible and feature dual lip labyrinth seals for maximum protection against sweat and the elements and to contain the 90% high pressure water proof grease, keeping everything running smoothly for the duration. The Angular Contact (A/C) design of Enduro headset bearings allow all balls in the bearing to engage the load, spreading the force over a larger surface area minimizing any possibility of premature wear and greatly extending bearing life.
