KS Dropper addict
I have several KS dropper posts (all of which are super natural's and one 150- insane amount of travel!) on each of my bikes in my quiver, I am quite familiar with the product.

-This recent purchase seems to be a newer version where the cable attaches to a small 1.5mm screw under the saddle. This was a very cumbersome task to wrap the cable around this screw and apply the right amount of tension in such a small place. Good luck if it slips during a ride... I'll have to remove the saddle to fix it. I'm not pleased with this design change.

Other than my one complaint the post quality seems the same as my others and it functions the same.

KS Supernatural Seatpost
A decent dropper post for the price paid, quality seems nice and the drop/raise action is smooth, weight wise its lighter than the KS eten I was considering with 25mm more travel. Installation instruction was minimal but any person with an average IQ should be able to figure it out. After a period of non-use the dropper tends to stick a bit, just raise and drop it a few times and it will go back to normal. The complaint I have is that the alan screw that holds down the cable inside of the seat post is so dam small and uses the smallest size possible that it strips very easily, this happened on my friends dropper after he had to rewire it because the cable stripped, luckily the alan screws on my old handle bar grips work and he cut those down to size to make it fit. When this dropper runs it course I'm going to try another brand.

PROS: Durable

CONS: Difficult To Install

I purchased th KS Supernatural because the ETEN was back ordered. Jenson missed the guarantee delivery date on the Eten and they told me they would give me a $10 discount on the Supernatural, I've yet to see that discount.

The delivery on the Supernatural was very fast, it arrived on the guaranteed delivery date in perfect condition and well packed.

Nice smooth action, fiddly remote cable lock screw
I bought this for a build because I didn't want to spring for a Reverb (have one on another bike) and I wanted to try out KS posts as I had researched and heard good things about them.

On the plus side, this post has a nice smooth action and the remote feels great. I like it's feel and actuation better than the Reverb as it seems to work with a lighter touch. You can't adjust the return speed but it seems perfect to me. The post looks good with its red anodized bits and the 2 bolt clamp holds the seat well although mine developed a creak after a while but some chain lube on the threads and heads of the clamp bolts fixed that.

On the minus side, the version they are selling now is the newer generation from 2014 on. It is not the post in the picture. This version has the cable going into the back of the seat head and it's sealed from gunk and theory. The bad part is that there's a tiny little allen screw in there that you're supposed to wrap the cable around and pinch it down. It wasn't that hard to wrap and pinch but as soon as you cut the excess cable off, the end frays everywhere and the bolt is very small and soft (2mm allen wrench) and I couldn't get it very tight without starting to strip it out.

After 4 or 5 rides and around 100 miles, my pinch bolt let go of the cable. Fortunately, this happened at home while I was cleaning my bike up and not on the trail. Of course you have to take the saddle off to do anything with the cable which sucks because I had finally gotten the saddle right were I wanted it.

My fix was a screw with a wide, flat phillips head. I created a loop in the cable end and crimped it with a small piece of brass tubing . When I put it all together, I used the tiniest bit of blue loctite on the screw and tightened it down. Now if the screw loosens up a bit, the loop should hold the cable and it can't slip. Time will tell. This would be a 5 star item and a great value in a dropper if it weren't for the screwy cable clamping.

Awesome seatpost!
This is a great seat post. Works right out of the box. The only cons are, once the bike/seatpost sits for an extended period of time, when you go to pull the lever, there is a little sticking with the post, but this is clearly stated in the paperwork and isn't a big deal. During my rides, I haven't had any problems. Again, only after sitting a while. The only other thing was, the lack of install instructions. But you don't have to be a bike mechanic to figure it out.

I'm hooked and never going back to a fixed seatpost again.

Excellent product
With so many adjustable seat posts, I was really overwhelmed with which one to go with. KS received great reviews and I am glad I bought it. Takes my riding experience to a whole different level. The only thing is it sticks on initial use so I have to pull up on it before my ride but that is not even an issue. Definitely a must own!

Good stuff but wrong picture
I got the new design (as shown on KS web site) with internal mechanism (no more exposed wire and lever). The routing is still to the top so the cable moves with the saddle.
This is good stuff. A much better value for the money compared to the LEV model that I also own. I do like both but went this time with the Supernatural for a less expensive build.

An Upgrade Must
This is one of those upgrades you think about getting, but keep holding back because of cost vs. function issues. In the end, it will transform the way you ride as well as the functionallity of your bike. In adition, It gives you more control, which makes for a safer and more comfortable ride.

I also have the X-fusion Hilo Sl, and Gravity Dropper Turbo and this KS seems to take lead. The Gravity is spring-loaded with only 3 positions and a little tricky to operate. On the other hand and along with the same endless adjustability of the KS, the X-fusion Hilo SL adds air pressure adjustability along with larger diameter tubing. Nevertheless, the KS feels like a better though-out product and it does not come loose when lifting the bike by the saddle like the X-fusion does (just a little annoying).

Overall and with all three of these being similarly priced, I would take the KS.

PROS: Easy To Install, Lightweight, Well Engineered, Attractive Design, Range Of Choices

CONS: Lacks Air Adustability

I assume the "R" stands for the right side of handlebar? Thanks
Robert on Jul 27, 2016
BEST ANSWER: Stands for remote. Means there is a button that routes to the bars. Others have a lever under the seat
