FSA ACB TH-873DJ replacement headset bearing, 1.1/8 inch, 41.0mm outer diameter with a 36x45 degree angle, in stock in Kennington, south London.
A single replacement headset bearing from FSA, the angular contact ACB TH-873DJ, sized for 1.1/8 inch forks with a 41.0mm outer diameter and 36x45 degree contact angles. Those three figures are what decide whether it drops into your frame, so check them against the bearing you are removing before ordering. It is a genuine FSA component, so it matches an existing FSA headset properly.
If your steering feels notchy, loose or stiff to turn, worn headset bearings are usually behind it, and a fresh bearing brings back smooth movement. Plenty of riders tackle this at home with basic tools, though it pays to take your time seating everything squarely. We have it on the shelf in Kennington for free click and collect, and our mechanics can press it in for you the same day if you would rather not.
