BACKGROUND

• e*thirteen’s SP30 Vario Covert dropper post is an integrated style of dropper post found stock as OEM equipment on certain Rotwild bike models sold in 2022 and 2023. The Vario Covert post uses a travel limiter clip to dictate the upper stop position. Early production versions used an o-ring to retain the travel limiter clip. In late 2022, the oring was changed to a wire clip.
