The Tangeseiki Technoglide ZS225X Zero-Stack Headset is engineered for modern frames using a 44mm straight head tube and a tapered fork interface. It delivers smooth steering performance with a focus on durability, precision and long-term reliability.

Precision Alloy Construction: Built from lightweight yet strong duraluminum alloy, the headset maintains structural integrity while keeping overall weight low. The CNC-machined components ensure accurate tolerances for consistent fit and stable handling.

With its smooth bearing action and robust construction, the ZS225X offers confident, precise steering and dependable performance for everyday riding and long-term use.
