KS is the latest company to enter the wireless dropper fray with their $699 Lev Circuit. It's available with up to 200mm of drop, which is 30mm more travel than the longest Reverb AXS. Now, this isn't the first time we've seen a wireless dropper from KS – a prototype was on display at Eurobike all the way back in 2016, but it wasn't until late last year that that a production version hit the market.

There are 31.6 and 30.9mm versions of the Circuit, with travel set at 125, 150, 175, or 200mm. I've been testing the 31.6mm, 200mm version for the last three months, enough time to subject it to plenty of rain, mud, and generally messy conditions.
Lev Circuit Dropper Details

• Travel amounts: 125, 150, 175, 200mm (tested)
• 30.9 or 31.6mm diameters
• Adjustable air pressure to alter return speed
• IP67 water resistance rating
• MSRP: $699 USD
• Weight: 739 grams / remote: 45 grams

DETAILS

The internals of the Lev Circuit are almost identical to the non-electronic version, it's just that the orientation is flipped – the air valve that can be used to adjust the return speed is located at the bottom of the post, and a small motor at the top opens a valve to actuate the post when the remote is pushed.

The Lev Circuit is powered by a 450mAh rechargeable battery that slides in just behind the seat clamp. On their website, KS touts the benefits of a rechargeable battery over a disposable one, saying that it allows riders to “contribute to a greener approach and help reduce their carbon footprint.” You know what's even greener than a rechargeable battery? Not using batteries at all...

The main battery is said to provide up to 8 weeks of run time under normal use, and it can be recharged with the included charger in 4.5-hours. The wireless dropper remote uses a CR2032 battery, and has an LED indicator that changes from green to red when the battery needs to be replaced, typically after 8 months of use.

A single bolt clamps the seat rails in place, and then the angle is adjusted via a 3mm Allen key at the front of the post.

The battery slides into the back of the post's head and is locked into position with the latch at the bottom.

INSTALLATION

Getting the Circuit up and running is dead simple – insert the post and clamp it down, install the remote, and then pair the system by pushing the button on the top of the post and the smaller recessed button on the remote. Honestly, the only slightly challenging part was figuring out that a cap hides the saddle angle adjustment screw – I was used to the configuration of a Reverb AXS, so it took me a couple of extra minutes to get things sorted out.

Installation is when all the measurements start to matter, and this is one area where the longer overall height of the Circuit could become an issue. Similar to the the TranzX post I reviewed in September, the Circuit's length below the collar is fairly short at 291mm for a 200mm post, but the motorized mechanism adds around 15mm to the overall height.

That means if you had a Circuit and, say, a OneUp dropper, the Circuit would need to be inserted 15mm further into the frame than the OneUp in order to achieve the same saddle height. For riders on bikes with short seat tubes and plenty of insertion room that won't be an issue, but it's something to keep in mind if you're trying to fit a post with the maximum amount of drop.

The return speed can be adjusted via the valve at the base of the post.

PERFORMANCE


The Circuits remote lever is large and easy to reach, and the response time is very quick. The amount of force required on the saddle is fairly light, and the post slides smoothly out of the way without much effort. It'd put it on par with the RockShox AXS Reberb post as far as how much (or little) effort it takes to get the seat out of the way, and ahead of the TranzX EDP01 – the post didn't operate as smoothly as the Circuit.

When it's time to raise the seat for a climb, holding down the the remote returns it to full extension. This is where the AXS Reverb has the edge – that post extends much more quickly than the Circuit. I inflated the Circuit to 180 psi, the max recommended, and even then I'd call the return speed adequate but not amazing. On rides with more rolling terrain where the seat is constantly being adjusted the difference between the Circuit and the AXS Reverb is noticeable. The same goes when comparing it to a Fox Transfer – the Circuit is a little less eager to fully extend. Of course, not every one wants a super-speedy post, and I wouldn't call the Circuit slow, it's just not the fastest out there.

I didn't have the time (or patience) to test out KS' claim that the Lev circuit will get 12,000 actuations out of a single charge, but I can say that the run time is more than adequate. I never had the post die out on a ride, and I'd usually charge it every 2-3 weeks depending on how much I'd been riding, or whenever the thought crossed my mind.

One final note on performance is that if you have the post compressed and go to lift up a bike by the saddle it'll extend slightly, a trait that I've only experienced on KS posts. I know, you're technically not supposed to pull on a seat with the dropper lowered, but it happens, and WTB even has a saddle with a built-in handle. It's a fairly minor detail, but one that's worth a mention since I haven't experienced it on any other posts in recent memory.

It's not pretty, but it works surprisingly well. This is the fix I came up with after accidentally breaking the remote lever.

DURABILITY / SERVICE

Part way through testing I accidentally broke the thumb paddle off the remote. I'd laid my bike on the ground and was stepping away from it when my shoe snagged on the plastic lever and ripped it off. That's 100% user error, but it did illustrate that the lever can break fairly easily. The quick fix I came up with involved putting a ferrule over the actuator button, and covering it with mastic tape. It's not pretty, but it actually works very well, and I'm not really sure why KS went through the effort of creating a thumb lever – a simpler push button design would have been easier to execute, and would probably be more crash resistant too.

Opening up the post to give it a refresh is as easy as removing the nut at the bottom of the post and unthreading the collar to slide the stanchion out of the lower. There was still plenty of grease when I pulled the post apart after 3 months, but it was clear some mud and grit had made it way past the wiper seal. A quick cleaning and a fresh coating of grease took less than five minutes, and the entire procedure is a sub-15-minute affair even when working at a leisurely pace.


PRICE / WEIGHT

At $699 the Circuit sits between the $861 Reverb AXS and the $499 TranzX EDP 01. Of course, there's no 200mm Reverb AXS, so riders looking for that length will be choosing between the TranzX and the KS. The KS does lower more easily than the EDP01, and the battery lasts longer, but $200 is a pretty substantial price difference.

When it comes to weight, the 739 gram Circuit is just 28 grams lighter than the TranzX, so I'd call it a draw. Even without the weight of cable and housing, adding a battery and a motor to a post creates a heavier product - a 210mm OneUp post weighs 592 grams, and even after adding in 60 grams for cable and housing you're still looking at an 87 gram weight difference.

Pros

+ Smooth & light action when dropping seat
+ Long battery life
+ Easy installation

Cons

- Middle of the road return speed
- Remote is a little flimsy
- Expensive





Pinkbike's Take


bigquotesFor me, wireless dropper posts still fall into the 'neat, but not necessary' category. There's no shortage of cable-actuated options that are reliable, affordable, and don't require remembering to charge a battery, and that's the direction I'd point most riders.

That said, for those who want a post that's easy to install (or swap from bike to bike), and creates a clutter-free cockpit, the Lev Circuit is worth a look. I wouldn't mind a slightly faster return speed and a more robust remote, but the long battery life and the fact that there's a version with 200mm of drop does make it a good option.

 @fabsmf: you should probably make it and sell it. You could be sitting in a couple dozen million coins...
There is a reason why most brands put out Wireless droppers at around 600 - 800 usd... there is a warranty which raises costs.
For example i had a mild issue with my AXS dropper, they sent me a new one with no questions asked. I even had the chance to keep the one with the mild issue which was easily resolved and keeps working perfectly.
Its a complete package. I believe that axs barely needs any service whatsoever which makes its worthwhile UNLESS you forget to charge your bat or not carry another E.g on the derailler or backpack

 @fabsmf: yeah 100 could be about right. Then there's cost for development, marketing, overhead, dealers margins, warranty, the list goes on. Finally you'll end up at 699 msrp. So? Love it or leave it, nothing to be mad about.

 It shocks me that has SRAM not come out with a 200mm wireless option already...I get that the insertion depth numbers wouldn't be as impressive as OneUp's dropper or other mechanical droppers but a lot of bikes now have plenty of insertion depth clearance to make it work.

 My guess is they are working on a new version of the AXS Reverb and waiting to do 200mm with that one.

 Maybe they're just too busy with the whole motor-seatpost-drivetrain integration and reckon a longer post wouldn't fit because the motor gets in the way. They forgot there are unassisted bikes too.

 What would be the average "insertion depth" and IF there's clearance how can you compensate for her benefit?
  • 24 5
 Am I the only one who has trouble with single bolt seat clamps? Because of the constraints of the battery and motor, every electronic dropper has a single bolt clamp (the Reverb, Magura, TransX, and now this KS), but I've never had a good experience with a single-bolt seatpost. Either the head slips while riding hard or it can't be micro adjusted to get the saddle in just the right position. By contrast, double-bolt clamps are infinitely adjustable and extremely secure. Having a saddle in the wrong spot drives me nuts, so it's weird to me that anyone would pay more for a luxury product that likely makes your bike fit worse.
  • 22 2
 The older style single bolt clamps were no good, but with the posts you mentioned there’s a second bolt towards the front of the post that allows for fine tuning of the angle, and helps to lock everything in place more securely. I haven’t had any of the the new ones slip.
  • 4 0
 @mikekazimer: That's really good to know. I've been avoiding single bolt seatposts for years not knowing about the angle bolt!

 @mikekazimer: I have to adjust my saddle due to slippage on my AXS every other ride.

 @pivotpoint: somethings not right. I’ve never had to adjust mine. Ever, and I’ve never heard a single one of my buddies mention it with their AXS either. Nothing but good reviews
  • 3 0
 @pivotpoint: Are you using an accurate torque wrench? The torque they want is kind of scary high, but I've only had mine slip once, and that was due to me basically falling on the nose of the seat. I've broken saddles before so for me, 1 slip in like 2 years is better than a broken saddle.

 Kind of makes me want to get one of those Flipper tools to see if these wireless droppers can be easily hijacked. It would be loads of fun to sit by a busy trail and make riders posts drop down repeatedly halfway up a long climb. Good thing I'm too lazy to ever do that. Maybe when I'm retired.

 The reverb AXS also extends if you lift it with the saddle down, at least mine does. Generally it doesnt happen if I lift it from the rear, but if I grab the nose of the saddle the post extends slightly.

 @pisgahgnar: I've found that when I'm really careful about only lifting the bike with the post fully extended, I do NOT need to perform venting at all. I think that picking the bike up with the seat down lets it extend a bit, and the negative pressure may suck some air in. Give it a try

 @Ignaciosc22: yeah it develops squish, so not only do you lose some seat height, but on hard pedal strokes you feel the post bouncing you around a bit. the vent procedure firms it right back up to normal. i ride 6-10 hrs per week on trail and if i'm not careful how I pick my bike up have to vent every 2 weeks or so. once I started being careful, venting basically wasn't needed anymore.

 I was once that person who would build the best of the best bikes with all the top components and suspension. I now just but a year old bike and rip it. The money spent on "the best" just isn't worth it at all. The performance gains are barely noticeable if at all. Only thing I'll upgrade now is wheels since they have a good money to performance ratio. Spend the money on travel and beer.

 $699 is silly when you can get a great wired option for half the price. I can’t understand how Bluetooth and batteries double the price point for a dropper post.

 This goes for a lot of wireless stuff mounted on the same small and simple vehicle yet here we are. Wired bicycle computers (so with a wire between the magnet-sensor and the computer mount) are considerably more expensive than the wired ones. But when people want to have it installed by the shop mechanic (hence have to pay for installation), wireless is cheaper. I wouldn't expect it to pay off similarly with these seatposts (though headsetroutingcoughcough...) but it may still pay off for the audience that happens to own multiple bikes and want to share the same dropper between those bikes.

All this said, people also run wireless Reverbs which are more expensive and people call for the longer travel so yeah, there is demand.

 There are "wireless" droppers out there for well under $100. You just have to use your hand on the lever under the seat.

 @vinay: "for the audience that happens to own multiple bikes and want to share the same dropper between those bikes."

This is only valid if the wireless dropper is cheaper than equiping all your bikes with cheaper wired droppers, which most of them aren't unless you own more than 4 or 5 bikes.
  • 7 1
 I would have no problems running one on an e-bike or a bike with electronic transmission if you can share the battery but not if it has to be charged separately, I would 100% forget to charge it separately.
  • 8 2
 The main reason I liked the AXS dropper was it had the same battery as my derailleur and had a very long life. So when I of course forgot to charge my derailleur and got a low battery warning, I could swap my batteries out and make it home just fine. Built in backup! Too bad the dropper sucked in nearly every other way.
  • 6 4
 @nathan-likes-stuff: I have run all the droppers. I have an AXS that is the best dropper ever. No problems for three years switch across multiple bikes. Maybe you had a bad one? The AXS Reverb has arguably the best feel of any dropper. Super precise and easy to put in any position you desire.
  • 2 1
 @nathan-likes-stuff: Also there is the convenience factor of not having to deal with a cable.

You'll have to pry my AXS derailleur out of my cold dead hands, but Reverb AXS I sold after a couple underwhelming months of use.

 The Limotec EP1 looks promising. Kinda takes away the ability to swap between bikes if it has a cable running to the motor tho. Hopefully it's not $700 tho

 Mine has been working great. It does take noticeably less effort to lower the dropper compared to the reverb. It is a tad slower on extension if you like super fast extensions. One other advantage not mentioned is that it has a lot less lateral play than the reverb.

 I wish more dropper post had air valves located at the base - most of them are tucked so deep inside the top of the post and require at least 250PSI that trying to adjuts the air pressure is super tricky at best. Damn near impossible on some models

 See, this is the big plus about wireless. You can stick it on the bottom, then just pull the whole thing out for a refill. I hate screwing with my saddle to refill air

 "The internals of the Lev Circuit are almost identical to the non-electronic version." Not sure I understand how a 2032 battery which costs about $2 and a "small motor" adds up to an additional $450?

 I think bike companies are seeing that the sort of people who wants electric components on their bikes are also the sort of people who buy things specifically because theyre more expensive, because having expensive things helps them prove that theyre better than the people with normal things.

 I still don’t get it how come none of the brands release a dropper with no remote, just a small button underneath the saddle. I believe a big chunk of “slopeduro enduro trail whatever but not on a dh rig” riders use the dropper only once to pedal on a fire road or to pedal for the local meetup at the job park, for these it would just be so cool. And when they go full “bike park” mood they can just put a reguler seatpost in and good to go. Not all people are looking for no cables on the dropper to impress the dentist friends on the group ride.
  • 1 1
 @Silentgeorge: Yes I know some very trashy droppers exist with a lever under the saddle, but they are in really low travels, looks shitty, has 1 screw clamping mechanism, and the lever is huge and disgusting. Some brand should come up with a 170ish travel, 2 bolt clamped version made for a stylish bike, with a small 1-finger lever or even a button, an in really cheap. I bet you a lot of bikepark riders would buy it for the short pedallings they need in their life.

 I’ve had two KS dropper. Both broke in weird places. The rear of the lever on one of them after the gentlest of strikes with a leaf. One the little metal catch that held the cable within the seat post. So, my experience is, KS droppers are flimsy yet expensive. My Fox Transition is now 8 years and still going strong.

 SRAM is assuredly working on a revision or new version of the AXS dropper. Just like the AXS der can run off the house battery of a SRAM PT powered ebike, the new SRAM AXS dropper will do the same thing. This should also serve to reduce the stack height that is introduced by keeping the batter at the seatpost head. That will be a winner. It should be able to do the same thing with a meat powered bike with a small house battery...sounds a lot like Shimano Di2 (what's old is new again).

 I think I last replaced the cable on my dropper about 4 years ago.
  • 1 3
 My wired dropper rattled a lot, so I decided to add some isolation foam. As my mechanic skills suck, ended up with removed cable. And cable routing on my bike quite complicated (requires to remove bb, even if you have tools with magnets for routing).
So, now I'm choosing from:
1) buy wireless dropper
2) buy bb tool and torque wrench (40nm) and do the thing (already have magnet tool)
3) bring my bike to bike shop (most boring option)
  • 5 0
 Bb tool and a torque wrench is the cheapest and most logical. I dont think a torque wrench is needed IMO, I dont use one for bbs.

A bottom bracket tool will pay for itself the first time you need to replace the bearings. I got one that attaches to a 3/8 wrench for like $10.

But if your mechanical abilities are really low taking it to a shop would be the wise thing to do.
  • 3 0
 If you are replacing cable housing you can just attach fishing line or an old cable to the old housing before removing it, that way you have a guide running through the frame so you can just pull the new stuff through, it’s super simple, doesn’t help if you are building a frame but for replacements it’s so easy
  • 1 0
 @xciscool: new frames always come with plastic guides so it is a non issue. Insert a long cable to the guides from one end. Once it sticks out, insert the housing on that other end and push back the guide progressively until it exits the frame. Done.

You can remove that temporary cable and do your build.

 @RonSauce: please tell me your frame isn't carbon.

 @cookiemonster615: the threads aren't carbon in carbon frames. 40nm is a decent amount of torque and its not like the threads are going to walk out on you anyway if you only give it 30. For a threaded bb you will be fine as long as you aren't using long breaker bar.
  • 1 0
 @RonSauce: that's all true, but I do believe that it is better to torque things within the given torque ranges. Those ranges exist for a reason. It matters less for bbs than for stem bolts on carbon handlebars, but it is still important. I would personally have an issue with over-torquing things, so I use torque wrenches whenever I have access to them. I hit the 54nm torque spec on my Truvativ cranks pretty easily (I have the Park Tool TW-6.2, which eases the job of getting to those higher torques).
  • 1 0
 @cookiemonster615: there is a huge difference between a carbon cockpit thats 4-5nm and a bottom bracket at 40nm. Unless 23 and me has shown you have 10% gorilla DNA you should be able to stop when the bb is tight.

 This is what struck me the most. The battery is so green you have to replace it every 8 months. Like what?!

 Ok now it says it’s the remote battery. I’d swear it wasn’t there before… or just my reading comprehension sucks

 "On rides with more rolling terrain where the seat is constantly being adjusted"

?!?!?!?!?!

 I don't know if it's just me, but I feel like return speed isn't that big of a deal. If your dropper returns to the raised position in .3 seconds compared to .7 seconds, does it really affect your riding at all?

 .3 vs .7 seconds.... might be the difference in scrotal pain after unintentional impact

 It' something you have to adapt to. The combination of a slower return speed and the lack of a distinct top out "clunk" means you have to just kind of wait for a while before releasing the dropper button to endure it returned all the way.

I have the TransX and it works fine, but I had to adapt to it. I definitely prefer speed and clunk of other posts.

 @wheelsx2: The circuit has a very noticeable top out clunk.

 I'm running a fox transfer v2 (factory) and the return speed on it is what i describe as slow. my wife rides the same post (albeit not the factory) and it returns quicker. i have had issue with mine returning fully and i wonder if it was faster, it might have more momentum to return completely. I did have it rebuilt by fox and it came back more or less the same as when i shipped it out. and yes, the torque on the seatpost collar is to spec and i've basically tried everything to make it a better post.

 @fakeendurobro: with a Transfer, you’re lucky it comes back up at all.

 @stevemokan: It's a shame. I have the same issue with my V2, but the V1 post from 2017 is still fantastic.

 Some of these people clearly never ran a Specialized dropper and it shows.
That thing could drop you to the ground faster than you could say "dropper post" when it clipped you in the no-no zone.

 @nickfranko: never had this issue with mine, don’t know if people are just hovering with their balls above the seat letting the saddle smash them or what’s going on…

I like the fast return, press the lever, bam and it’s up.

 @pmhobson: some bike shop guy has a hypothesis that when fox updated the post, they reworked how the nitrogen is filled into the post. he claimed the nozzle used to add the nitrogen is thinner than previous versions and, due to the amount of applications each nozzle is used for, weakens at the bend, thus less nitrogen in the post without the person knowing it. not sure if the hypothesis holds air, but certainly the post doesn't.

 I would only use a wireless dropper if my bike didn’t have cable routing

 "if you have the post compressed and go to lift up a bike by the saddle it'll extend slightly, a trait that I've only experienced on KS posts."

Bullshit it's the only brand you've experienced it on. All Reverbs have this issue, and a few others as well. And you've definitely tested bikes with a Reverb. Don't throw KS under the bus all by itself, that's quite disingenuous.

OneUp posts seem pretty immune to it, and the Fox Transfer was explicitly designed to be able to handle it with the use of a spool valve instead of a poppet valve.

 to be honest wireless dropper posts arent that good, the ones with wires would be easier to fix might i add, the idea is supes cool tho

 "...when the battery needs to be replaced, typically after 8 months of use."

So the battery needs to be replaced every year or two?! Ooof.

 Yes, but that’s referring to the CR2032 battery in the remote - those are really common and inexpensive.
