6707 2RS - ABEC-3 Radial Bearing for Internal Headset - 35 x 44 x 5mm - Generally used as an upper Headset bearing in the Acros AI-70 Headset that is very popular headset on many Canyon Bikes. This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, double seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements. 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 water proof grease, so you never have to guess if there is grease inside. Enduro Max-type bearings are designed without retainers to maximize the number of balls to spread the force over a greater surface area, decreasing friction and minimizing wear. Enduro
