4444S Mountain Bike Headset, Black

Key features

• 4444S BIKE HEADSET KIT: Includes 1 bicycle headset kit for compatible mountain bike frames. The 4444S designation helps identify the 44mm semi-integrated headset style for straight steerer applications. Please check your frame and fork dimensions before ordering to confirm fit.
• 44MM SEMI-INTEGRATED DESIGN: Designed for a compatible 44mm head tube with a semi-integrated headset configuration. The ZS44/28.6 specification corresponds to a 44mm frame interface and a 28.6mm (1-1/8 inch) upper steerer dimension. Verify the required headset standard and dimensions for your bicycle.
• ALUMINUM ALLOY CONSTRUCTION: Made with aluminum alloy components, this bicycle headset kit offers a lightweight, practical replacement option for compatible mountain bikes. The black finish pairs with a range of bicycle styles and component setups.
• CHECK HEADSET SPECIFICATIONS: The 4444S code is a convenient search reference, not a substitute for accurate measurements. Confirm the upper and lower headset cup dimensions, fork steerer diameter and required SHIS specifications before purchase. ZS44/28.6 and ZS44/30 refer to different dimensions and should not be assumed interchangeable.
• REPLACEMENT FOR MTB BUILDS: Suitable as a replacement headset for compatible mountain bikes using the specified semi-integrated configuration. Check your original headset markings and bicycle manufacturer's specifications before installation. Correct fit and proper installation help the headset function as intended.
