Restore the crisp, responsive handling of your bicycle with the genuine SPECIALIZED 1.5” ACB 45x45º Lower Steering Bearing. As a critical component in your bike´s headset assembly, the lower bearing endures significant stress from rider input and terrain impacts. Over time, this can lead to gritty steering, unwanted play, or a "notchy" feeling that compromises control and confidence.

By replacing your old component with this precision part, you are not just fixing a problem; you are investing in the long-term performance and safety of your bike, ensuring predictable control when you need it most.
