The Cervelo FSA Lower Headset Bearing 1-1/2", 36x45 is a replacement bearing assembly designed for use in compatible Cervelo frames with a 1-1/2" lower headset interface. It provides smooth, precise rotation at the fork steerer and frame interface, supporting accurate steering response and reliable handling across varied riding conditions.

This bearing unit features complementary contact angles of 36x45°, engineered to balance load distribution and promote durability under both axial and radial forces. The geometry helps maintain consistent contact with the headset cup race, reducing binding and friction during steering inputs, descents, and technical maneuvers. This contributes to a stable and predictable ride feel.

Manufactured to tight tolerances, the bearing surfaces and races are finished to enhance smooth articulation and long-term 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
