The Cervelo FSA Upper Headset Bearing 1-1/4", 45x45 is a replacement bearing assembly designed for use in compatible Cervelo frames that accept a 1-1/4" upper headset interface. It delivers smooth rotational performance at the fork steerer and frame interface, supporting precise steering response and reduced friction during handling inputs.

This bearing set features 45x45° contact angles that help balance load distribution and durability, promoting stable performance whether climbing, cornering, or navigating varied terrain. The geometry maintains consistent contact with headset cup surfaces under varied load directions, reducing binding and enhancing steering precision over time.

Manufactured to tight tolerances, the bearing surfaces and races are finished to support smooth articulation and extended service life when correctly installed and maintained. Proper lubrication and periodic inspection help preserve performance and minimize the risk of premature wear from contamination or high-mileage use.... Read More
