BLACK OXIDE: Enduro bearings use races made from a 52100 chromium alloy and high-quality carbon that have undergone both thermal and cryogenic treatment. This means everything is brought to a temperature of –190°C, which provides 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 allows for easy installation. The races are further polished after treatment to ensure the smoothest possible surface. These are the best bearings for full suspension frames. LLU: Similar to our LLB type seals, the LLU is a contact seal where the double "lips" are housed in a recess of the inner ring. Guaranteeing better sealing, these seals are ideal for suspension pivots or headsets that are constantly in contact with salt, sweat, and dust. This better seal and the 2 "lips" help to retain 90% of the grease we use on the bearings, thus protecting it from moisture and continuously lubricating the balls and the race.
