We do not propose bearings for lower-end headset ranges. Instead, we start with chrome steel, Black Oxide A/C, and finally 440C stainless steel bearings. They are always constructed with the largest possible balls and their double-lip seals are seated in a small recess for ultimate protection against sweat and the elements. They are 90% filled with high-pressure grease, so you don't have to wonder if there's grease inside. BLACK OXIDE: Enduro bearings use races made from 52100 chrome alloy and high-carbon steel, which has undergone thermal and cryogenic treatment. This means everything is brought to a temperature of –190°, which provides a certain hardness and thus reduces ball wear. We then give the bearing a magnetic treatment (black or Black Oxide color) which provides protection against corrosion and also allows for easy assembly. The races are further polished after treatment to ensure the smoothest possible surface. These are the best bearings for suspension linkages.
