- FSA/TH Industries TH-873 headset bearings, pair
- 1-1/8″ threadless, ACB 36°x45°
- Dimensions: 30.2mm ID x 41mm OD x 6.5mm
- Fits most 1-1/8″ integrated/semi-integrated headsets
- Compatible with IS41 headtube standard
- Includes: two (2) bearings
Condition: Used, pulled from an FSA headset. Bearings are in excellent shape — seals are intact, no play or roughness. Smooth spin with no grit. Plenty of life left.
Notes from MyBikeThing: These are the most common 1-1/8″ headset bearings out there. If your steering feels notchy or gritty, fresh bearings make a huge difference for a few bucks. TH-873 fits FSA Orbit, No.57, and dozens of other headsets using the IS41 standard. Swap takes five minutes with a headset press — or just drop them in by hand on most integrated setups.
You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition 🙂
