FSA ACB Headset Bearing 36x45 1-1/8" Black Seal MR122 Info
The FSA ACB Headset Bearing 36x45 1-1/8" Black Seal MR122 is a direct-replacement angular contact bearing designed to keep your headset running smoothly under load. Built to FSA's ACB (Angular Contact Bearing) standard, it uses a 36x45-degree contact angle geometry intended to handle the combined radial and axial forces that headsets encounter during everyday riding and hard cornering.
The black sealed design helps keep contaminants out of the bearing races — a practical advantage for riders who log miles in mixed conditions or simply want a bearing that holds up between service intervals. As an OEM-spec part, it slots directly into compatible FSA headsets without modification, making it a straightforward swap when worn bearings start introducing play into your front end.
