A single FSA Micro ACB stainless headset cartridge bearing for 1 1/8 in headsets, with 45 degree by 45 degree contact angles and a blue/gray seal.

Compatibility

• Note: A 45 x 45 degree bearing is not interchangeable with a 36 x 45 degree bearing, even at the same steerer size.
• How to check yours: Headset cartridge bearings are identified by inner diameter, outer diameter, height, and the two contact angles. Pull your old bearing and read the code stamped or etched on it, or measure it with calipers, and match all of those numbers before you order. OMG's bike shop can identify and install headset bearings.
