FSA ACB Micro Headset Bearing – 36×45 mm, 1 1/8″ Standard

Description

The FSA ACB Headset Bearing Micro 36×45 – 1 1/8″ is a direct-replacement angular contact bearing designed to restore smooth, precise steering to 1 1/8″ headsets. The 36×45-degree contact angle geometry handles both radial and axial loads simultaneously — the combination that defines proper headset bearing performance under real riding conditions.

FSA’s ACB (Angular Contact Bearing) series is built to the tolerances you’d expect from a manufacturer that supplies headsets to professional road and mountain teams. Whether you’re servicing a worn-out headset or keeping a second set of bearings on hand, this micro-format bearing fits a wide range of 1 1/8″ headset cups from FSA and compatible third-party systems.
