ENDURO BEARINGS 6806 LLB OSID

6806 LLB OSID - 1-1/8 Headset Bearing (30.2 x 42 x 7mm: 45deg ID only) This 1-1/8 Drop-In, Internal Headset features 52100 High-Carbon Chromium alloy races paired with grade 10 Balls with 90% fill, high-pressure, water-proof grease. This only application for this bearing size is as a direct replacement for some Pinarello bikes. 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 line is, 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. Enduro
