The Rollcii EC34 Headset is an external cup headset designed for performance, durability and long service life. It is suitable for frames with a 34mm head tube and 1-1/8" steerer tube setup.
A headset is an important part of the front-end steering system. It directly affects steering smoothness, fork stability and overall riding feel. The Rollcii EC34 uses AC sealed bearings, helping protect the bearings from dust, moisture and everyday dirt while maintaining stable steering performance over long-term use.
This model features CNC-machined aluminum alloy components, balancing lightweight construction with structural strength. For riders looking to replace a worn headset, clean up the cockpit setup or build a custom bike, it is a practical and easy-to-match option.
The EC34 standard is commonly used on steel frames and 1-1/8" straight steerer fork setups. Rollcii offers multiple anodized color options, including black, silver, orange, blue, purple and gray, allowing you to match the headset with your frame, stem, spacers or other components for a more complete cockpit look.
If you are looking for an EC34 headset with sealed bearings, CNC alloy construction and multiple color options, the Rollcii EC34 Headset is a practical choice for single speed bikes, steel frames and custom builds.
⚠️ Please note: this product includes the headset only. Fork, stem, headset spacers, top cap and display props are not included.
⚠️ Please confirm your frame head tube size, steerer tube size and crown race diameter before purchase.
⚠️ Headset installation requires proper pressing and adjustment tools. Professional installation is recommended.
⚠️ Actual color may vary slightly due to screen display and anodizing batch differences.
