A dropper seatpost works with hydraulic or mechanical power. The bike rider uses a lever (usually located on the handlebar or seatpost) to easily lower the seatpost as they are riding. The lever moves hydraulic fluid or a mechanical cable through the hose to raise or lower the seatpost.

What is the purpose of a dropper seatpost?

A dropper post, commonly referred to as a dropper, is a replacement for your bicycle's seat post and allows for quick adjustment of saddle height without requiring you to get off your bike or even stop moving. Most droppers work through cable actuation, although there are a handful of electronic/wireless posts.

Is a dropper seatpost worth it?

It's a pity, because using a dropper seatpost enhances your riding. Actually, it does more than enhance, it noticeably changes the way you ride. A dropper seatpost, used properly, gives you more confidence, more manoeuvrability, more control, more traction and, obviously, more speed.
