Upgrade Your Ride with Precision Steering: The DEDA IN-4 Integrated Headset
Experience a new level of steering precision and reliability with the DEDA IN-4 Integrated Headset. Expertly engineered for both demanding road cyclists and rugged mountain bikers, this component is a cornerstone of high-performance bicycle Steering Systems. It is designed to provide flawlessly smooth rotation and long-lasting durability, making it the perfect upgrade or replacement for your premium build with a tapered 1 1/8” – 1 1/4” fork. Enhance your bike´s handling and responsiveness, and feel the immediate difference in every corner and on every climb.
The heart of the DEDA IN-4 lies in its superior ACB (Angular Contact Bearing) design. These high-quality chrome steel bearings are meticulously engineered to handle both radial and axial loads, which translates to exceptionally fluid steering action under pressure and a significantly longer service life compared to standard bearings. This advanced system ensures that your front end remains stable, predictable, and free from play, giving you the confidence to push your limits. A standout innovation is its full compatibility with the revolutionary Deda H.S.S. (Headset Stack Spacers) system. This allows for a seamless and aesthetically superior integration of spacers directly over the headtube, creating a clean, professional, and aerodynamically optimized cockpit.
Finished with Ded´s exclusive graphics and a sleek Polish on Black (POB) finish, the IN-4 headset adds a touch of Italian class to any bicycle. To perfectly match your bike´s aesthetic and performance goals, it is available with either a lightweight alloy top cover or a premium, weight-saving carbon top cover. At just 73 grams, this headset delivers robust performance without a weight penalty, making it an essential part of any modern, lightweight bicycle setup. Choose the Deda IN-4 for a superior connection between your frame and fork, and unlock the true potential of your bike´s Steering Systems.
