Strummer HS-EC34-BT Threaded Headset

The Strummer HS-EC34-BT is an External Cup (EC) type headset designed for frames with a head tube diameter of 34 mm and threaded forks of 1-1/8 inch. This headset uses Angular Contact Bearing (ACB) sealed bearings to provide smooth, stable steering rotation that is more resistant to dust and water.

The aluminium alloy with anodized glossy finish provides a combination of lightweight, good strength, and a neat appearance. This headset is compatible with quill stem diameter of 25.4 mm, making it suitable for use on bikes with a classic threaded fork system.

The bearing can be replaced and serviced, making maintenance easier and extending the lifespan of the components.
