Leaving your MTB dropper post compressed for an extended period of time is not recommended. When the dropper post is compressed, the internal air pressure is increased, which can put additional stress on the internal components of the dropper post, potentially leading to premature wear and failure.
Additionally, leaving your dropper post compressed can cause the hydraulic fluid to become trapped on one side of the post, which can affect its performance when you next use it. This could lead to damage to the seals and other internal components over time.
To maximize the lifespan and performance of your post, it’s best to store it in the fully extended position when not in use. This will help to ensure that the internal components are not subjected to unnecessary stress or pressure and that the hydraulic fluid is distributed evenly throughout the post.
