Blackbearing IS42/30 Lower Headset Bearing

The Blackbearing IS42/30 Lower Headset Bearing is designed to deliver smooth steering and long-lasting durability for integrated headset systems. Built with tight tolerances, it ensures consistent performance and secure alignment between the fork and frame.

Optimized for 1-1/8" Forks: Compatible with 1-1/8 inch (30mm) fork steerers, this bearing fits frames with a 42mm inner diameter at the head tube. Its integrated design provides a clean, low-profile setup, reducing weight and enhancing the bike’s overall aesthetics.

Durable and Low-Friction Design: Manufactured to high standards, the IS42/30 bearing minimizes friction for smoother rotation and better handling. Its durable construction ensures reliable performance across miles of rough terrain or wet weather riding.

Sealed for Longevity: Fully sealed against dust and moisture, it maintains smooth steering and prevents contamination. The Blackbearing IS42/30 Lower Headset Bearing offers an ideal blend of precision, protection and long-term reliability for discerning riders.

Following the SHIS specification (IS42/30 for lower headset position), it guarantees precise fitment and easy replacement on modern road, gravel and MTB frames that use the same standard.
