The dropper post actuator works by using a cable connected to a handlebar lever; pulling the lever tugs the cable, which then activates the actuator, allowing the dropper post to move.
Here's a breakdown of the process:
- Handlebar Lever: The rider operates a lever, typically mounted on the handlebar.
- Cable Activation: Pushing the lever pulls a cable. This cable runs from the lever down to the dropper post. According to provided information, "Pushing the lever pulls the cable, which tugs on the dropper post actuator and allows the dropper post to move up or down."
- Actuator Engagement: The cable is connected to the dropper post actuator. When the cable is pulled, it activates the actuator mechanism.
- Post Movement: The activated actuator releases or engages a locking mechanism within the dropper post. This allows the rider to compress the seat down to a desired height. Releasing the lever and, therefore, the actuator, allows the seat to return to its extended position, typically using an internal spring.
In essence, the dropper post actuator acts as a remote switch, controlled by the handlebar lever, to enable vertical movement of the seat post.
