Review on Tranz-X Jump Seat: Cable-Less Dropper Post - The Ultimate Riding Companion by Brock Chisholm

I have balance issues stopping my bike and a little bit when starting. This is made worse by the fact that the seat is high enough for full and efficient pedaling, which means my feet don't touch the ground when I'm stopped and I have to lean the bike or on a pedal must stand - balancing - to lean in the opposite direction. Doesn't always work, fell down several times. With my most efficient legs, the distance from the crank to the ground is obviously too great. This seat allows me to quickly lower the seat before stopping and raise it quickly and automatically for efficient movement. Very easy to install, convenient to use, seems durable. Since I have to let go of the handlebars with one hand to squeeze the lever, next time I'll buy a [more expensive] cable driven version for my other bike, but that drop down seatpost is amazing. Measure your bike's down tube to get the correct diameter. good investment
