I-Beam Compatible Gravity Dropper Turbo: Previewed

Have you wanted to take advantage of an adjustable height post, but not wanted to give up your trusty I-Beam seat? Thanks to Gravity Dropper you are now in luck. Inside you'll find info and pictures of their latest I-Beam compatible telescoping seat post.

Read on...Gravity Dropper has been manufacturing adjustable height posts in their U.S. facility since 2003 and now offers three different models to suit most rider's needs. The Descender is the lightest at 365 grams (claimed) and is controlled via a knob on the post itself for those who are looking to minimize bar clutter. Down the road when you realize that a remote makes too much sense not to use one can be added as well. The Classic post is remote operated and the go-to option for a lot of riders. Claimed weight is 510 grams and drop options range from 2" to 4" lengths. The third is the Turbo model that we'll take a closer look at below.


Adjustable seat posts come in a few different flavors, mainly mechanically or hydraulically controlled. All of Gravity Dropper's posts fall into the first category by using a coil spring to return the post to full height and a cotter pin that holds the post in place. Inside the Turbo you'll find a very simple system that is designed to be reliable without depending on oil or air (or the seals needed to keep either in place). Pushing on the remote lever pulls the cable which slides the cotter pin out from its hole. Now the post is free to move either up or down. If you have a multi-position post, simply release the cable's tension at the right moment and let the spring loaded pin pop into the correct hole. Keeping the Gravity Dropper wiggle free are two replaceable plastic glide blocks. There is no metal on metal contact between moving sections as the the glide blocks act as a shim between any moving parts.

Unlike most telescoping posts, the Gravity Dropper's cable entry is stationary on the seat post's lower tube. This is great to see as managing the excess cable from a lowered seat post can sometimes be a hassle. Anyone who's lowered their post only to hear the buzzing from the suddenly large loop of housing hitting the rear tire should appreciate this bit of info. The CNC'd aluminum remote is available in either left or right hand versions to work well with whichever hand you'll find it easier to use. It features a split clamp, like most brake levers, to make installation or removal quick and painless.


The Gravity Dropper Turbo that you see here is the first of its kind with an I-Beam compatible seat post head. As the amount of I-Beam seats has expanded over the last few years, more and more riders have been switching over to the single bolt and rail system. The standard head uses an infinitely adjustable system that lets the user find the exact seat angle and fore/aft position that they feel most comfortable with.

In only a few short years height adjustable posts have managed to open a lot of rider's eyes to the possibility of being more confident on technical sections without having to dismount to adjust saddle height. While many times more expensive than a standard QR seat post collar, an adjustable post obviously has many advantages and can simply add more flow to your ride, as well as being safer than tackling the challenging bits with your standard post at full extension. After a few years of running different models, I am of the belief that nearly every rider can benefit from installing an adjustable post on their AM, and even dedicated XC bikes.
