Engineered for tapered steerer forks (1.125" x 1.5"), this integrated headset delivers precision performance in bikes requiring 42mm top and 52mm bottom head tube dimensions. The 36°/45° chamfered bearing design pairs with premium 440C stainless steel races for durability and smooth rotation. Features a concealed preload adjuster, crown race, and compression ring for streamlined aesthetics and reliable adjustment without compromising structural integrity.
Built with Enduro's commitment to longevity, this headset incorporates 440C stainless steel balls and races paired with dual-lip seals at both bearing positions. The 90% bearing fill combined with high-pressure waterproof grease ensures superior protection against contamination and moisture ingress. Backed by a lifetime warranty, it's engineered to outlast your bike.
This drop-in headset combines a 1-1/8" upper bearing (30.5mm ID, 41.8mm OD, 6.3mm width) with a 1-1/2" lower bearing (40mm ID, 52mm OD, 6.5mm width) for seamless integration into IS42/52 head tubes. Both bearings feature stainless steel construction and are recognized across multiple industry standards. The kit includes an upper spacer (HD-120) for added flexibility, with optional lower spacer (WA-36 1x150) available separately to fine-tune stack height and clearance around your fork crown and head tube interface.
