You will need this Top and preload kit if you plan on running the EDC tool inside your steerer tube. You can also use a standard top cap with a starnut or compression plug (but you cannot use the EDC tool system)

The special collar allows you to preload your headset without the need for a traditional compression plug. The top cap fits the EDC tool system so you do not need to thread your steerer tube.
