Secure your headset with confidence and protect your carbon steerer with the FSA Compressor Bolt Plug, an essential component for any bike with a carbon fiber fork.

The FSA Compressor Bolt Plug is a meticulously engineered expander plug designed to provide a secure and non-damaging solution for pre-loading headset bearings in a 1 1/8" carbon steerer tube. Unlike a traditional star nut, which can damage the delicate carbon fibers, this plug expands evenly inside the steerer tube, creating a rock-solid anchor point for your top cap. This ensures your headset is properly tensioned for smooth, precise steering and eliminates any play. The lightweight and durable design is a crucial piece of the puzzle for maintaining the integrity and performance of your carbon fork.
