Cyclists with carbon fiber bikes, this FSA Compressor Top Cap is exactly what you need for proper headset assembly! Designed specifically for carbon steerers, this top cap system replaces the traditional star nut assembly that can potentially damage carbon fiber tubes. The complete kit includes the cap, bolt, and expander - everything you need for a secure and professional installation. The black carbon fiber top cap looks sleek and modern on any bike, adding that pro touch to your setup. The Compressor Carbon Pro design is engineered to distribute pressure evenly across the carbon steerer, preventing any potential damage while ensuring your headset is properly preloaded. Installation is straightforward for anyone familiar with bike maintenance, and the quality of materials is exactly what you'd expect from FSA - durable, precise, and reliable. Whether you're building up a new carbon frame, replacing a damaged top cap, or upgrading from an older system, this top cap assembly delivers the performance and safety you need. It's compatible with 1-1/8 inch steerers, which covers most modern road and mountain bikes. The attention to detail in the manufacturing means everything fits together perfectly without play or slippage. For serious cyclists who want their equipment to be both functional and safe, this is one of those small components that makes a big difference in your bike's performance and longevity.
