The TranzX Jump Seat Dropper Seatpost is the easiest to install and the easiest to operate on the market. Just bolt up your favorite saddle in the simple one-bolt clamp and you're ready to go; no cables to fuss around with. Pull the lever under the saddle and use your body weight to drop the saddle; pull it again to return to full height or anywhere in between. Dirt jump and park riders can slam the seat for air time and raise it up to ride home without risking tangled cables or carrying tools. Commuters, cargo bike riders, and tandem stokers can use the Jump Seat for easy dismounts and to put their foot down flat at stops.


  • Easy installation, no cables or housing
  • Simple operation - just pull the lever and sit
  • Infinitely adjustable in range
  • Sealed air cartridge

Had it for almost a week now. So far so good. Super easy to use and install. It will add some weight to the bike, but not a big deal. I hope it last cause is one of my favorite parts of the bike right now.
