For someone who compulsively reads bike industry news and gear reviews, I can actually be quite the Luddite when it comes to my own bike. I ride a hardtail with a 1×10 drivetrain that I hardly ever tune, and that’s part of the beauty of my bike. So when I started thinking about using a dropper post, it was really the idea of adding another moving part that turned me off. When it came down to it, though, I was sick of compromising on seat height – and so were my knees. I wanted the power that comes with good leg extension but also wanted to be able to move around the bike freely, and that meant not having my seat in the way. I realized that ultimately, the post would pay for itself if it kept my knees healthy and more than make up for its own weight if it improved my pedaling efficiency and descending capability. In the end, this post seems to have done both, and I’m sure most any dropper would. So there’s my basic argument for these wonderful pieces of mountain bike tech.
- Super smooth action.
- Infinitely adjustable seat angle.
- Intelligent cable routing method without cable growth.
- Ergonomic carbon lever can replace an ODI inner lock-on grip clamp.
The Lev’s action is at least as smooth as Rockshox’s Reverb, which seems to be today’s benchmark for droppers. I could detect only a very small amount of play at the seat when wiggled off the bike. It feels solid once sat on, though, with little flex and no noticeable play. The seat clamp is a traditional, infinitely-adjustable two-bolt design, which didn’t slip or strip like some single-bolt posts. I found the carbon lever to have a very ergonomic feel and didn’t have any trouble with control spacing after mounting it to my grip.
I chose the Lev for its cable routing: KS wisely routes the cable to the collar on the top of the post’s slider – a static point that sees no movement as the rider cycles through the post’s infinite travel. To me this is an essential feature for an externally-routed post; other companies route the cable to the head of the post, which means that there is a lot of extra cable hanging off the bike when the seat is at the bottom of its range. Of course, this is a moot point if your frame features internal routing. Many users (myself included) are also making an improvement to the post’s cable routing by adding a v-brake noodle in between the lever and the housing. This provides some direction to a cable which is otherwise a bit awkward and unsupported. Overall, the KS is the most refined (though also most expensive) post on the market. It’s function is flawless and user-friendly.

- The air port’s location under the saddle means removing the head of the post every time pressure needs to be adjusted. Of course, this shouldn’t need to be done much, except maybe during initial setup.
