The Enduro ACB 4545 150 SS is a 1-1/2" angular-contact headset bearing designed for extreme durability. Built with 440C stainless steel balls and races, it offers the highest level of corrosion resistance against rain, sweat, and road grime. It serves as a premium replacement for industry part numbers like TH-070, MR-128, and MH-P16.

Engineered for protection, it features LLB dual-lip seals and Almagard 3752 waterproof grease to keep contaminants out. The angular-contact design ensures even force distribution across the internal balls, reducing wear and extending the bearing's life in the most demanding riding conditions.
