PRO Spider Expansor for 1 1/8 HeadsetsEnsure the integrity and performance of your high-end cockpit with the PRO Spider Expansor, an essential spare part for any cyclist running a modern threadless headset system with a carbon fiber steerer tube. Designed with precision and reliability in mind, this expander plug provides the critical internal support needed to properly preload your headset bearings, guaranteeing smooth, responsive steering and protecting your valuable components from damage. It is the professional-grade solution for a secure and stable front end, giving you the confidence to push your limits on every ride, from demanding climbs to technical descents.The primary benefit of the PRO Spider Expansor lies in its ability to deliver consistent and secure compression without harming the delicate structure of a carbon steerer tube. Unlike traditional star-fangled nuts that can cause delamination or cracking in carbon, this expander uses a robust mechanism that expands outwards to grip the inner walls of the steerer tube firmly and evenly. This results in a flawless connection for your top cap and compression bolt, allowing for precise adjustment of headset preload, eliminating play, and ensuring the longevity of both your fork and headset bearings. Its lightweight design is a testament to PRO´s commitment to performance, adding minimal weight while providing maximum security.Main Features:- Carbon Steerer Safe: Specifically engineered for use with carbon fiber steerer tubes, preventing any risk of damage associated with traditional headset spiders.- Secure Clamping Mechanism: Provides a reliable and evenly distributed anchor point inside the steerer tube for consistent headset preload and adjustment.- Enhanced Steering Precision: By enabling correct headset adjustment, it eliminates play and contributes to a more stable, responsive, and predictable steering experience.- Durable & Lightweight: Constructed for long-lasting performance and reliability without adding unnecessary weight to your performance-focused bicycle.- Universal Compatibility: Designed to fit the industry-standard 1 1/8 inch steerer tube diameter, making it a versatile spare part for a wide range of modern road, gravel, and mountain bikes.The Modern Alternative to Traditional SpidersIn the world of bicycle headsets, the term ´Spiders´ or ´star-fangled nuts´ refers to the classic component used to set preload in metal steerer tubes. However, for carbon forks, a different approach is mandatory. The PRO Spider Expansor is the advanced solution, functioning as a compression plug that replaces the need for these traditional spiders. It offers superior protection and a more refined method of adjustment, making it the non-negotiable choice for any rider with a carbon steerer tube.Specifications:- Material: Aluminum- Diameter: 25 mm- Diameter opening: 8 mm- Thickness: 15 mm- Size: 1 1/8 inch- Weight: 7 grams. tradeinn Bikeinn
