The Enduro ACB 3645 SS Angular Contact Headset Bearing is engineered for smooth steering and long-term durability in compatible bicycle headsets. Manufactured with 440C stainless steel balls and races, it provides excellent corrosion resistance, particularly in wet conditions and environments exposed to sweat and moisture.

Efficient Load Distribution: The angular contact design distributes steering loads evenly across the bearing balls, reducing concentrated wear and supporting consistent headset performance. Hardened stainless steel construction provides strength and resistance to mechanical wear.

Advanced Sealing: LLB dual-lip seals and Almagard 3752 waterproof grease help protect the internal components against contamination. The sealed construction retains lubrication and supports dependable operation during regular riding and demanding conditions.
