1-3/8_ Angular Contact Bearing for Internal Headset featuring anti-corrosion Black Oxide/Magnetite coating of 52100 High-Carbon Chromium alloy races paired with grade 10 Balls. The Enduro line of headset bearings begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure waterproof grease, so you never have to guess if there is grease inside.
