Enduro's angular-contact headset bearing combines Black Oxide-treated chromium steel races with premium engineering for uncompromising performance. A multi-stage chemical treatment creates a 3-micron anti-corrosive layer while simultaneously enhancing hardness through heat treatment. The races undergo precision super-grind polishing to achieve a mirror-smooth rolling surface. Oversized grade 10 balls distribute loads evenly across a larger contact area, reducing wear and extending bearing life. Dual-lip seals with micro-groove labyrinth design and 90% fill of high-pressure Almagard 3752 grease provide comprehensive protection against moisture and environmental degradation—essential for reliable headset performance in demanding conditions.
