We do not propose bearings for headsets of the inferior range. 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 (of nature). They are 90% filled with high-pressure grease, so you don't have to wonder if there is grease inside. BLACK OXIDE: Enduro bearing uses races made of a 52100 chrome alloy and high-quality carbon which has undergone thermal and cryogenic treatment. This means that everything is brought to a temperature of –190°, which ensures a certain hardness and thus reduces wear on the balls. We then give the bearing a magnetic treatment (black or Black Oxide colour) which provides protection against corrosion and also easy assembly. The races are additionally polished after treatment to have the smoothest possible race. These are the best bearings for the suspension swingarm.
