Product Description - Store the EDC Tool in your steerer tube. The EDC Top Cap from OneUp Components is required if you want to store the EDC Tool or EDC V2 Tool in the steerer tube. It is screwed into the steerer tube using the EDC Top Cap tool, which is located on the EDC Multi-Tool. There it pretensions the headset and thus takes over the function of the star nut. Before this, however, a thread must be cut into the tapered fork steerer tube. Afterwards you can store the EDC Tool. Also included are several spacers and a Steerer Plug, which keeps grime away from your steerer tube.
