You might be wondering if it's really worth it to buy a Dropper Seatpost. Seth from Seth's Bike Hacks has put a great video together on "Why use a dropper post?" - Check out the video bellow!
Once you get accustomed to having a dropper post, you’ll use it all the time. For mountain bikers who have never tried riding with the saddle down low, the benefits may not be immediately obvious. If you fall into that category, I encourage you to drop your saddle and try jumping around a bit. You may find that you can do things you couldn’t before, like maneuvering on to and over pretty big stuff.
