Strummer HS-EC34-BT is an External Cup (EC) headset designed for frames with a 34 mm head tube diameter and a 1-1/8-inch threaded fork. This headset uses an sealed Angular Contact Bearing (ACB) to provide smooth, stable steering and greater resistance to dust and water.
The aluminum alloy with a glossy anodized finish combines light weight, good strength, and a clean appearance. This headset is compatible with a 25.4 mm diameter quill stem, making it suitable for bicycles with a classic threaded fork system.
The bearing can be replaced and serviced, making maintenance easier and extending the component's service life.
