Sim Works is proud to announce SimHeads ($150) by Tangeseiki, a premium headset developed in collaboration with one of Japan’s most respected precision component manufacturers…
The SimHeads is based on Tangeseiki’s Technoglide Classic model—the most durable and precise offering in the Technoglide series—SimHEADS is custom-specified to meet SimWorks’ performance and durability standards.
Tangeseiki manufactures its own bearings in-house, a rarity in modern bicycle component production. The stainless steel bearings used in SimHEADS feature machining accuracy of ±0.004mm and mirror-polished raceways. Combined with an angular contact bearing structure, this results in exceptional rotational smoothness, durability, and long-term performance under load.
Unlike conventional headsets that rely on cost-saving 6000-series aluminum for non-rotating components, SimHeads utilizes A7075-T6 aluminum for the crown race and top cap, matching the material used throughout the rest of the assembly. This material choice delivers approximately double the tensile and yield strength, improving durability while maintaining a consistent, high-quality finish across all components.
We trust Tangeseiki because they control the entire manufacturing process, from bearings to final assembly. That level of precision is essential when the goal is to eliminate the gap between rider intention and bicycle response.
SimHeads will launch initially in standard Threadless 1-1/8” headset format, with the potential for additional standards to become available in future production. The product is intended for riders who value precise steering feel, long-term reliability, and components manufactured without compromise.
