OneUp Components EDC Top Cap + Preload Kit - a clever solution

The OneUp Components EDC Top Capp with Preload Kit is an ideal solution for those who want to store the EDC Tool System in the steerer tube, but are afraid to tap a thread. It contains an EDC-compatible Top Cap, headset Preloader, headset spacers (40 mm in total) and an EDC Steerer Plug. With the Top Cap you have the choice between seven attractive colours. The reason why so many Enduro World Series Pro riders use the OneUp EDC Tool in the event of a mechanical is because this tool set is right there and contains everything you need. OneUp Components wanted to benefit even more riders - including those with steel and carbon fork steerer - and developed this solution to do so.
Important: The whole thing works only with the OneUp stem. This is because it has a recess on the underside of the body into which the Preload Kit is inserted, whereby you adjust the preload via a third screw on the fork steerer clamp. The Preloader consists of a conical split wedge clamp with clamp bolt and nut, which is connected to a conical headset spacer. When you tighten the bolt on the back of the stem, the Preloader closes, the internal cone is tightened and the conical headset spacer is pushed down away from the stem, which preloads the headset. The EDC Steerer Plug is required for stowing the EDC tool system and is compatible with most tapered steerer tubes.
