FSA Headset Bearing ACB TH-870E 1.1/8 45x45 41.8mm 4545
This is a replacement headset bearing for FSA ACB (Angular Contact Bearing) headsets. It's designed for 1.1/8 inch forks and uses the 45x45 degree angular contact design, which is standard on many modern road and gravel bikes. If your bike has an FSA headset and you're noticing play or stiffness in the steering, a worn bearing could be the culprit. This bearing is a direct replacement part for the TH-870E model.
Headset bearings wear over time from riding, especially in wet conditions or if your bike doesn't get regular maintenance. Swa
