Drop grams, along with your seat.

Not only does the KS LEV Dropper Seatpost offer the reliably smooth travel that makes KS dropper posts some of the most popular on the market, but it also shaves precious grams with its titanium clamp bolts, carbon lower clamp, and carbon remote lever. Reducing weight even more, its PowerCordz cable is 75% lighter than the stainless steel line that's used on most dropper posts. The rest of the post is made of aluminum for durability.

As expected from a high-quality dropper, the LEV Dropper Seatpost uses hydraulic internals that remove play/excess movement from its design. However, most impressive is the stationary connection near the non-moving part of the post. This provides a better fit that's customizable to your frame without the cable bunching up or getting in your way, as there's no need for the excess cable to accommodate seat movement.

Good so far

I've used it several times

I purchased the KS Lev for my Specialized Camber Evo which has weird partial internal cable routing for the Specialized Command Post. So far, I am really happy with the Lev. Installation was simple and it looks clean on the bike. The function of this dropper really makes it unique. It is cable actuated but it has infinite height adjustment as compared to pre-set heights. The re-bound speed is adjustable and quick enough. The lever isn’t great in a 1x setup but it’s fine on my 2x XC oriented bike.

Can't be discounted enough

I returned this product before using it

One of the most important parts broke upon installation and I never got to use this. All the parts arrive in a small plastic bag and are very simple to assemble: Lever, cable housing, cable, ferrule, spring, and hook/set screw for the connection with the seatpost actuator cable end. You cut the cable and housing to length when installing it. I followed the instruction manual and when just ready to connect the cable hook end to to other cable end, it just snapped off. No more cable end on the seatpost - it's ruined already. It appears to be a filament, like fiberglass strands, glued on and they are weak and not durable. I am glad this happened in the garage and not on a ride. This particular post is junk and I suspect they all suck as much and eventually fail. Really disappointing for me. I now understand why it was on sale.

Works great - when it works

I've put it through the wringer

Love the dropper functionality. It completely transformed my ride. The KS Lev (non-stealth routing) is awesome because the linkage is static at the bottom of the post. Less than a year later, the dang thing stopped locking in position, and needed to be rebuilt. Getting started on a warranty now, either way the post is going back on my bike, but the hassle of not having my bike for a couple weeks is a tough pill to swallow.

First dropper post I've owned

I've put it through the wringer

This thing totally transforms the riding experience. Now, instead of feeling like I'm gonna go over the bars on the really steep sections, I just drop the seat and get down/into the bike and go with it. Hitting downhill turns are easier too because when the seat is down you can get low and drive the tire treads into the dirt and rail it. I have so much more confidence in my riding now. Downside, a few months after the 2-year warranty expired the seat started the dreaded "sag" when I sat on it (I used in mostly dry, dusty SoCal conditions and cleaned after every ride.) It was ready for service. REI took care of it for me by sending it off to the authorized repair center, charged $65 total--new cartridge I believe. Took two weeks! The post is now tight as new, even the tiny bit of left/right wiggle is gone. During those two weeks I discovered how dependent I'd become on the LEV, riding was either filled with stops to raise/lower seat or I was caught riding uphill with seat down or tentatively dropping into steeps which I could have easily hit if my seat was dropped. People complain about droppers needing service, but it's just like your shocks that need periodic service--you have to do it. They are pricey... wait for a sale, then jump on it.

For an initial investment of $30 (for tools and oil), you can service the KS Lev yourself to cure a sagging post and return function to like new. See the "DIY KS Service" thread at mtbr. A tub of Slickoleum (=Slick Honey) for periodic lubing is another $20, which will last you 15 years. And for $20/year in replacement parts (dust wiper, copper guides, bushing, o-rings, quad-rings), you can keep your post running smoothly indefinitely.

Works for me

I've put it through the wringer

Good product for a good price. I've yet to have a problem with this. It goes up and down when I want it to. No complaints on my end

Cable sucks

I've put it through the wringer

As soon as you get this, open the package and throw away the cable and housing that it comes with, just so you don't have to even mess with that disaster. Ironically this is what 2 bike shops told me when I was trying to find a replacement power cable that broke on my second ride. Use a normal shifting cable and housing and make sure use the set screw when installing. Once you eliminate that problem, this works flawlessly. The fixed location on the seatpost makes this far superior to the other external droppers where the cable is constantly moving up and down. There is a small amount of play in the main shaft out of the box but it's on par with every other dropper I've seen. The dumpster fire of the included cable system easily deducts a star from this product. I truly can't believe they would include such a poor quality cable on such an expensive and otherwise excellent post.

Flawless so far.

Had it for over a year now, and I ride A LOT. I usually get in no less than 30 hours of mountain trail time per week, and so far, this dropper post has been absolutely trouble free and has functioned flawlessly. Also, a fair share of my rides are in wet and muddy conditions here in Washington state. All I do is wipe it down with soapy water after each ride. Don't know why anyone would rate this less than a full 5 stars. Never even had to adjust the cable since I set it up, and the thumb-button is a great design.

I'd give it a negative star if I could

I returned this product before using it

First of all the cable and housing that come with this post are absolute garbage. They're wound so tightly in the package that they have preset kinks already in them. I wasn't even able to feed the cable (plastic btw) through the housing it was so bad. Upon realizing this I grabbed a standard derailleur cable, which it says it's compatible with, to feed through. Now that I got a cable through I proceeded to thread it through the spring and end clip that actuates the post. Doing this was pretty uneventful except for difficulty bending the cable back into the clamp mechanism. I managed to do this while cutting the cable to the right length. However, the set screw that clamps the cable in place is not compatible with standard derailleur cables. The screw will not sit flush with the clamp, creates interference, and will not allow it to actuate. After realizing this I decided to at least try to hook it on and see if it would actuate. Apparently they use a plastic cable internally on this as well because this broke and pulled out. My seat post collar was not tightened, so that eliminates any possibility that it was bound up from anything I did. Overall I'm extremely disappointed with this dropper. I can get over the crappy cable and housing that was supplied, but the clamping mechanism and internal cable seem really poorly designed. Seriously, who thought it would be a good idea to use a plastic cable internally? After this experience I can say I will stay far away from any KS products in the future....

Best Lev Yet.

I've used it several times

Mountain bikes have become so good in this decade that we are left to consider the smallest of details when considering a bike purchase. Frame geometry, suspension, and components are all so refined that when a new frame design comes out, all anyone can talk about is where the water bottle will go. The situation is similar with dropper seatposts. A lot of bad ones have fallen by the wayside, and the current offerings are all well-designed and reliable. So why choose on over another? It comes down to the details. I chose the KS Lev Ti because is offers the best cable routing of any externally-routed post. instead of entering the post up near the saddle, leaving a moving loop of housing behind the seatpost, the Lev's remote cable meets the post at a port near the seatpost collar. This port can be clocked to any postion, so it sets up clean whether the frame runs the cable on the right or left side. After a few rides, I'm completely pleased with the performance of the Lev Ti. The elegant aluminum-and-carbon remote had a very light action, and initiates with a flick of my left thumb. I find it easy to make tiny adjustments to saddle height, even over rough terrain. Plus, the refined, all-black finish looks great on the bike! My only criticism of the package is with the included Power Cordz cable and housing. The cable strips and frays easily, and the housing was coiled in an oval shape, so that it was impossible to st up nicely. Plan on using different cable and housing to set up the post. Jagwire shop items cost a few grams, but work great. Most new mountain bike frames coming out will accomodate an internally routed dropper remote, but there are some great frames that still need an external remote. For those frames, the KS Lev ti is a great choice.


What is the minimum distance that this post will accommodate? I have short legs, and on my current bike setup have only about 7-1/2" from the top of the seatpost collar to the saddle rails. Is that enough space for a 125mm dropper in this model? thanks! john

The KS website has schematics for all of their seatposts. I had a similar question but found out that the seal collar to rail dimension is what you are really looking for. This length for the 125mm model is 184mm (7.25") and the 100mm is 159mm (6.25") so you'll just fit with the 125mm model.
