Enduro bearings ACB 68025 CC - ABEC 5 - Black Oxide (angular contact) - 33.15x46.9x6.5 (36x45°)

We do not suggest bearings for the inferior range of head tubes. 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.
