XLC HS-I23 A-Head Semi-Integrated Headset | ZS44/28.6 EC44/40 | For Tapered Forks
Experience a new level of steering precision and control with the XLC HS-I23 A-Head Semi-Integrated Headset. As a crucial component of your bicycle´s steering system, a reliable headset ensures smooth, responsive handling on every ride. Whether you´re building a new bike from the frame up, upgrading an existing ride, or looking for a high-quality replacement spare part, the XLC HS-I23 offers an exceptional balance of performance, durability, and value. This headset is meticulously engineered to provide a solid and dependable connection between your fork and frame, giving you the confidence to push your limits.
Unlock Superior Steering Performance
At the heart of the HS-I23 are high-quality, sealed cartridge bearings. This premium design provides an incredibly smooth turning action while effectively shielding the delicate internal mechanisms from dirt, water, and grime. The result is a low-maintenance headset that delivers consistent, fluid performance ride after ride, in all weather conditions. Say goodbye to notchy, unreliable steering and enjoy the buttery-smooth feel of a well-made component.
Modern Compatibility for Increased Stiffness
Designed for modern bicycle frames, this headset is specifically made for frames with a 44 mm headtube and is fully compatible with tapered forks (a 1-1/8″ upper steerer tube and a 1.5″ lower). This tapered design is the industry standard for performance bikes, offering significantly increased stiffness and strength at the crucial head tube junction. This translates to more precise steering input, better control during high-speed cornering, and enhanced confidence when descending or navigating technical terrain.
Sleek Aesthetics and Robust Construction
The semi-integrated (Zero Stack upper, External Cup lower) design allows the headset cups to integrate cleanly with your frame. The upper cup sits nearly flush within the head tube, providing a sleek and modern aesthetic that complements any bike´s profile. Constructed with lightweight and robust aluminium cups and race, the HS-I23 strikes an ideal balance between weight savings and long-term durability, ensuring it can withstand the rigours of both demanding road and trail riding.
