Precision Steering Performance for Tapered Headsets

Description

The Blackbearing D20 40x49x6mm 45/45° Headset Bearing delivers consistent, play-free steering with a durable, low-friction feel designed for premium cycling performance.

Correct Fit for 1-1/2" Forks: Sized at 40mm (ID) x 49mm (OD) x 6mm (width), this bearing is made for 1-1/2" fork steerer interfaces—commonly used as the lower bearing on tapered headsets for modern road, gravel and MTB frames.

45/45° Angular Contact: A true 45/45° angular contact profile ensures stable load distribution under braking and cornering, improving headset alignment and extending service life.

Chrome Steel Construction with Seals: Precision-ground chrome steel balls and races provide excellent hardness and wear resistance. Integrated seals help keep out water and grit for smooth performance in real-world conditions.

Factory-lubricated with high-quality grease, the D20 drops in cleanly and runs quietly, reducing maintenance while keeping your steering light and accurate.

Features
  • Optimized Fit for 1-1/2" Forks: Engineered for modern tapered headsets, ensuring accurate alignment and stable steering under varying loads.

  • Durable Chrome Steel Build: Chrome steel balls and races provide high wear resistance and low rolling friction for consistent performance.
