It typically features high-grade steel races and balls, along with quality seals to keep out water and dirt, helping to extend service life and reduce maintenance intervals. Whether you are refreshing a worn-out headset or building up a new frame, this bearing offers a cost-effective upgrade that can noticeably improve steering feel. Ideal for road, MTB, gravel, and urban bikes alike, it is a smart choice for riders who value reliability, precision, and long-lasting performance in their cockpit components.
