Returns Simplified.The Enduro ACB 3645 3344 SS 1 1/8 SS Angular Headset Bearing is a premium 33x44x6mm (36×45) angular contact bearing, engineered with top-tier 440C stainless steel balls and races for unparalleled corrosion resistance and durability, especially in wet conditions or for frequently washed bikes. Unlike standard stainless steel, Enduro’s 440C alloy offers superior strength, hardness, and wear resistance, achieved through meticulous heat and cryogenic treatments. Featuring LLB type seals and CRC Marine Grease, these bearings are further waterproofed against the elements. Designed with the largest possible balls and dual-lip seals in a micro-groove, they provide ultimate protection against sweat and contaminants, and are filled 90% with high-pressure waterproof grease for long-lasting performance. Enduro’s angular contact design ensures all balls are engaged, distributing force over a larger surface area to minimize wear and extend bearing life.
