Purpose and benefit Precision headset assembly designed to deliver stable, smooth steering and longterm corrosion resistance. Ideal when you need a durable, lightweight interface between a tapered fork steerer and a 1.5' head tube. Key specifications (exact) Steerer: Tapered 1 1/8'1.5' 1.5' head tube requires a specific frame Made of stainless steel and aluminum alloy — lightweight, antirust, durable Bearing: Angula Bearings Why you need it Converts a tapered 1 1/8' to 1.5' steering assembly so you can use compatible forks and frames without sacrificing stiffness or reliability. Combines corrosionresistant stainless steel with a light aluminum alloy body to reduce weight while maintaining strength in loadbearing areas. Angula Bearings provide smooth rotation and consistent performance under repeated use, reducing steering play and maintenance frequency. Compatibility and installation notes Requires a frame with a 1.5' head tube. Confirm your frame's head tube specification before . Designed for tapered steerers with 1 1/8' upper and 1.5' lower diameters. Ensure fork steerer dimensions match these measures. Professional installation or correct tools recommended to ensure proper compression and bearing preload. Performance highlights Durable materials resist rust and wear in wet or corrosive conditions. Lightweight construction minimizes added mass to the front end while maintaining structural rigidity. Bearings deliver lowfriction, reliable steering response for both casual riding and more demanding use. Practical use scenarios Upgrading: a worn headset on a compatible frame to restore precise steering and reduce play. Fork swap: Install a tapered fork with a 1 1/8'1.5' steerer into a bike frame that accepts a 1.5' head tube. Trail and commuter use: Suitable for riders who need a corrosionresistant, durable headset assembly for mixed conditions and frequent use. Final considerations Verify frame and fork compatibility (taper dimensions and 1.5' head tube) before ordering. Maintains the original function and specifications: tapered steerer fit, 1.5' head tube requirement, stainless steel + aluminum alloy construction, and Angula Bearings for smooth operation.
