FSA ACB TH-072E cartridge headset bearing, 51.0mm with 36 x 36 angles, a replacement for a loose or notchy headset. In stock in Kennington, south London.
The FSA ACB TH-072E is a single cartridge headset bearing, the sealed ring that sits in your headset cup and lets the fork steerer turn smoothly. The numbers that matter here are the 51.0mm size and the 36 x 36 angular contact seat, so check those against the bearing you are taking out before ordering, as headset bearings vary a lot between frames.
It is the part you want when the steering starts feeling notchy, gritty or loose, or when you are building a bike up and need a fresh bearing rather than a whole headset. We keep this one on the shelf at our Kennington workshop for free click and collect, and if you would rather not press it in yourself, our mechanics can fit it the same day.
