ENVE Composites Fork Compression Plug

Yes, this plug is designed for standard 28.6mm (1-1/8 inch) steerer tubes. While it is engineered to meet ENVE's high standards for carbon forks, it will function with most standard carbon steerers that require a compression-style plug.

Carbon fiber steerer tubes are susceptible to damage from the sharp metal teeth of a traditional star nut. A compression plug expands against the inner wall of the steerer tube, providing the necessary tension for your headset without compromising the structural integrity of the carbon.

Installation is straightforward and typically requires only a standard 5mm or 6mm hex key, depending on the specific bolt head. You will need a torque wrench to ensure you tighten the plug to the manufacturer's recommended specification to prevent slippage or over-tightening.

Yes, this component is designed to be reusable. As long as the expansion mechanism is clean and the bolt threads are in good condition, you can remove it from one fork and install it into another with the same steerer diameter.

The plug is properly installed when it is secure enough that it does not rotate or pull out when you tighten your headset top cap bolt. Always follow the torque specifications provided by your fork manufacturer to avoid damaging the carbon steerer tube.
