ACB 3645 CC SXD - 1-1/8' Angular Contact Headset Bearing (30.2mm x 41mm 6.5mm: 36x45 deg)

Internal headset bearing featuring XD-15 races and balls to provide a lifetime corrosion resistance

The last headset bearing you will ever install into your bike.
These full XD-15 bearings are virtually identical in performance and torrosion resistance to our XD-15 Ceramic-hybrid bearings used for hubs and bottom brackets, but with XD15 balls that work better in the more abusive steering environment. The mechanical properties of XD-15 stainless steel balls provide a level of impact resistance superior to ceramic balls for headset application. Enduro testing of bearings with XD-15 balls and races have been run 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.
The Enduro line of angular-contact headset bearings start with Black Oxide treated Chromium steel races, steps up to full 440C stainless steel, and the top of the lines, lifetime-guaranteed, XD-15 aerospace-stainless (races and balls). They are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with high pressure water proof grease for the ultimate protection against sweat and the elements. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, decreasing friction, minimizing wear and maximizing life.
