BLACK OXIDE: Enduro bearings use races made of 52100 chrome alloy and high-quality carbon, which undergo thermal and cryogenic treatment. This means that everything is brought to a temperature of –190°C, which ensures 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 the suspension linkage. LLU: Similar to our LLB type seals, the LLU is a contact seal where the double "lips" sit in a groove of the inner ring. Guaranteed better sealing, these seals are ideal for suspension pivots or headsets that are constantly exposed to salt, sweat, and dust. This improved sealing and the 2 "lips" help retain 90% of the grease we use on the bearings, thereby protecting them from moisture and continuously lubricating the balls and the raceway.
