                                                About Tange Seiki

                                                Tange Seiki has been manufacturing precision cycling components in Japan since 1920, originally producing steel tubing before expanding into headsets and bottom brackets. Today the brand is synonymous with reliable, well-engineered bearing systems used across all disciplines of cycling.

                                                Their Technoglide series covers the full spectrum of modern headset standards — from fully integrated IS2 and IS24 systems to semi-integrated ZS and zero-stack configurations — making them a go-to choice for framebuilders and home mechanics alike. The T47 Bottom Bracket Conversion Kit further extends compatibility, allowing riders to run threaded bottom brackets in press-fit frames without compromise.

                                                Tange Seiki components are designed with longevity in mind. Precision-ground bearings, quality alloy cups, and tight manufacturing tolerances mean less play, less noise, and longer service intervals — even under demanding conditions. Whether you ride road, gravel, mountain, or commute daily, a Tange Seiki headset or bottom bracket is a dependable foundation for any build.

                                                At Swinnerton Cycles we stock a comprehensive selection of Tange Seiki headsets and bottom brackets to suit a wide range of frame standards and steerer tube sizes. If you need help identifying the correct headset for your frame, our team is on hand to assist.
