 I really don't understand why droppers need to be wireless... I get that it's easier to install, but once you install what is the benefit?
If you don't want to install a cable then pay a shop to do it - would still be way cheaper than a wireless dropper.
  • 26 5
 Only advantage I can see is that it is easier to transfer between bikes? It would still be a pain though by the look of the shifter mount...

 With the reverb, it's way faster actuation, meaning you can micro adjust it easier with just a tiny blip on the button, meaning you actually use it even more often than a normal dropper. Its why the magura vyron never caught on, when you pressed the button it unlocked it for a full second.

 neater cockpit and less rattles would be some of the other benefits.

 Got lucky on my last used bike purchase that the previous owner had upgraded to an AXS dropper. It has been flawless for the last two seasons of riding. Faster actuation, a cleaner cockpit, no cable to rip out of the lever if you crash (has happened to my son), no extra maintenance, can put a regular post in for service and not miss a ride by needing to take the bike in but yes, they are not cheap and I do worry about it being easily stolen.

 Easier to install between bikes, less cables to worry about, less chance of an extra internal cable rattling, clean cockpit, easier to disassemble for travel, more reliable feel on the trigger, etc.

 I also don't understand why they have to be internally routed also. The PNW externally routed droppers connect near the wiper seal (so it doesn't move up and down with the post), which in my mind would make setting up the cable and housing even simpler than the internally routed stuff. I think it's really just for looks without any added benefits. Like the seatpost version of headset routing.

 I switched to wireless dropper as I am running a 180mm bike and spend a lot of time at the bike park. That way I put a Thomson seatpost with SDG Fly saddle tilted to ride at the park and DH races, then put the dropper back in when I need to pedal on week day evening rides. My hardtail has a normal dropper and if I still had a DH rig my enduro would also be cable I don't see the point other than what I am doing, which frankly is quite niche I guess.

 There are several benefits and a couple drawbacks..... *You don't have to be seated to compress the post which is the number one benefit. Removing / installing the post is by far way easier, actuating is smooth not having cable friction or cable defects. Drawbacks are- they are Hideous looking, heavier, batteries required (forget to charge them or leave at home is misery) bulky levers that are buttons not actual levers, desired saddle height slightly dropped-not as easily obtained.

that said, I run regular cable actuated droppers.

 Switching between bikes or travel. My bikes are really big and just pulling the dropper right out would be ideal. That being said I would have to travel a lot to make it worth it.

 @mattmatthew: I had a KS years ago like this, and it was fine. But the mechanism to make it work added a layer of complexity where I could see stuff going wrong for sure. Plus a dropper is one thing where internal routing is pretty easy and looks a lot cleaner while protecting the cable from crashes and the elements.

 @inked-up-metalhead: You are one of the rare PB-ers that likes the Reverb. I like the Reverb, super smooth, adjustable speed, and fit seamlessly with SRAM Matchmaker. Most don't like the Reverb because of bleeding issues, but there is a trick to the bleeding. I haven't had to bleed my post in a couple of years. The post does slow a little in winter though.

 I am running fullsuspension MTB/eMTB rental comapny in Portugal.
Happily, I am not attached to any exact brand but tested a lot of different MTB bikes past years. Some of them it is nearly impossible to adjust saddle height because of dropper post cable routing.
External routing doesn't solve problem. Best is well designed internal.

So If you have rentals from specific brands I think it is only way..

and off course clean look, no broken cables during crash is advantage too..

 Word. And more or less the argument against any cable-less tech on a bike. And hey if you like it, buy it. But having tried electronic shifting....just didn't do anything special imo. But I think the industry can only continue to tweak tried and trued things like derailleurs and expect big price increases.

 They benefit you by having superior insertion depth due to not needing a cable actuating mechanism at the base. Additionally, you never have to worry about a cable binding.

 @james182: I've suffered from cable tear out too. I think the AXS Reverb is a revolutionary improvement in dropper posts. They just need to produce a 200 mm dropper now

 @tacklingdummy: AXS Reverb and standard Reverb are completely different beasts and I don't think @inked-up-metalhead was referring to the standard Reverb.

The complete lack of effort required when using an electronic control versus a remote has to be experienced to be believed (same applies to shifting gears).
  • 12 10
 @pakleni: Why? Do you ride 20 - 40 hrs on every single ride?

Most people are lucky to get a two hour ride in 1-2 times per week. That means at least five weeks of riding for the derailleur (~ 20 hrs), ten weeks of riding for the dropper (~40 hrs), five to six weeks of riding for the fork (~25 hrs) and six weeks riding for the rear shock (~ 30 hrs). Remotes and power meter/ pedal sensor need a battery change about once per year (350-400 hrs). If you stick to the SRAM system all the batteries interchange so a spare (or two if you are really concerned) has you covered. The weak point is the head phones (~ 8hrs).

And you forgot about tyre pressure sensors (~75-90 hrs)!

The battery "issue" is not really the issue people (who have probably never ridden AXS or Flight Attendant anyway) are making it out to be. If you can manage charging your phone most days then AXS is not a significant addition to the list of pfaff that is associated with mountain biking anyway.

 Also they all look to have quite a lot of stack so if you're pushing the max length for your frame you might not be able to use the 200mm.
  • 12 1
 They certainly don’t need to be wireless. But, I’ve never had a dropper work so flawlessly as my AXS dropper. I’ve never had to service it, battery life doesn’t bother me, and it’s one less cable to look at/replace/deal with.
  • 3 2
 @likeittacky: Because it goes up on it's own... wirelessly. The point isn't about adding going down on it's own. No one wants that because it eliminates the ability to micro adjust.

Wireless droppers are just about getting rid of the cable so you don't have to deal with installation of a cable or adjustment etc.

It's also about having more than one bike and one dropper post because you can just take it out and put it into any other bike whenever you want.

I'm not saying I would ever pay for one... I wouldn't. Not until they're half the price. Then I still might not because I don't want to have to deal with batteries. Just pointing out it's functionality and why some people like them.
  • 1 1
 Easier install but also should have a shorter insertion length since the actuation is in the head. Only crap thing is I’ve yet to see one longer than 200. Makes no sense, I’d think if I can fit a 210 internal cable oneup in my frame I should be able to fit a 220-230 wireless one since it’s about 15mm gone off the bottom of the post.

 I don´t get either the "it is easier to transfer from one bike to another". First because you need two bikes with same seatpost diameter and length. Second. If you have two bikes that use the same dropper post, you have to take the Seatpost and lever from one bike and put it in the other. All with the cons of charging two batteries and higher stack.

For the cost of a E-DSP, you can get a normal DSP and two levers, so you only have to move the seatpost. That is way faster and easier to do.

 And it’s heavier. I get the benefit if you are constantly changing droppers between frames (don’t actually know anyone that does this) but other than that it’s the worst place to spend extra $ on your bike. All the well priced cable actuated posts (OneUp, PNW, Crankbros, SDG, RF, Trans X) all work super well these days.

 traveling with an internal cable can be problematic and as well....... As a tour guide adjusting seat height a few times a week for different riders makes for a cable headache even if I help guide the cable in and out of the frame the tension seems to change and the droppers get to the point of needing service with a new cable or housing/ferrule issues

 After flying with my bike for the first time this summer and needing to remove the dropper to meet the weight limit of the airline, I am definitely more interested in a wireless. It would have to be for the right price, but kinking the cable and needing to do a bunch of mechanic-ing upon arrival was annoying.

 @andrewbikeguide: Charging something is a pain. End of the story... .
I have the AXS derailleur and I have an app (not SRAM) that tells me when to charge the thing. It's annoying to take extra stuff with me on trips just to be able to charge the batteries. Torn batteries also exist, so it's not an argument for batteries. At least not on the rear derailleur. The derailleur battery lasts me 20 hours before I charge it to make sure it doesn't run out of juice. So I have to charge it every two weeks.
The phone argument is kind of ridiculous.
Remember the days when phones had to be charged once a week? I laugh in the face of every Apple Watch user for that very reason. What is that? Daily charging? Sorry, that's absurd and the wrong way for the industry to go.

Since I have the AXS rear derailleur, I don't see that you need less or more power compared to an excellent trigger, nor that the AXS is faster than the cable. If I now have to compare my BikeYoke with the force required to push and how well/quickly the part works to anything else, almost everything else looks dated in comparison. Show me any dropper that can do 4000 miles without service and that has run through the winter with salt on the transfer paths. That is seized in the frame and had to be hammered out. After that it still ran like the first day.

Complete parts for the service 40 USD. If you buy your own oil.
The manufacturer specifies a range of oils, no special stuff. Service for a wimp like me in half an hour.

All the other things that are written here and speak in favor of the Wireless Dropper that I can see are only present in one case. The quick change between frames. But that's it honestly, it's BARELY faster.
Why? Different lever on the second bike with pre-installed cable. WHERE is the difference now? You can only have a difference here if you also take the trigger from the AXS on every bike.

On the points I can't see:
Cable rattling is something I don't know and my frame only has one internal cable. And my frame is a 161 Privateer, so it's pretty cheap. And my 161 has been ridden silently. NO rear derailleur was on it, so no chain slap, all cables external except for the dropper. The hub was also silent. If you hear a rattling noise from the dropper, your frame is just really bad in terms of quality.

Cleaner cockpit would be the case if the remote is not bulky and can work proper with a matchmaker.

I simply don't see the micro adjust as a reason because the mechanical dropper I have works so smoothly and immediately without force.
It's the same for traveling, I unscrew three screws on my mechanical. That's it, now I can take the dropper out of the frame and remove it. The cable remains in the frame and can be installed immediately afterwards. It all takes 3 minutes, absolutely no argument here.

@Balgaroth: I have done that too. Easy even with a cable. Seatposts are hollow. Push the cable inside and tape the trigger to the frame. Converted in 5min. No rattle if you done it right. But yeah its faster with a remote.

 @Serpentras: Thank you for some reason here.
I'm happy for all the axs users, it's a good system but I don't understand the "once you'll try you'll never go back". I have a reverb C1, and haven't had to touch it since installation. Just like my previous B1 that I only had to bleed when I had to replace my frame. Yes, the Axs operates much nicer than the B1. Compared with the C1 though the difference is minimal. Unfortunately even most mechanics I've met do not understand how to bleed the remote properly.
Not saying I wouldn't like an electric post, but so far there's still disadvantages such as the higher stack height that'd require me to reduce travel, and why would I bother with charging something when I already have a reliable system?

 They'd be great for rental bikes. Shop personnel adjust the set height of the dropper depending on the renter. The adjustment is a little clumsy because you have to make sure the cable has slack and don't kink the cable during adjustment.

 Between wireless gears or dropper, I would rather have a wireless dropper. If you ride your brakes Euro you get neater cable organization with less rattling and less maintenance to worry about. The actuation is the same 100% of the time and you don't need to change the cable every 6 months when riding in muckier conditions. That said, I think they are still very expensive and it's an investment I am not willing to make right now.

The frames that are definitely bad are evils. Self clogging machines are funny. Those designs are not well suited for all weather every day riding.

Like I said before, I don't need to change the shifter housing that much. I don't even change it if it works perfectly. It's absolutely out of harm's way so it can used for many years. The cable can go bad, maybe. Still didn't changed it for the last two years because it runs perfect. Good mechanical dropper with a good frame wrecks any current wireless dropper.
  • 1 0
 @Serpentras: did you ever own an evil? They are brilliant bikes in a lot of ways. I do agree that the design is a bit rubish if you ride in grainy mud. But that is the case for most full sus frames out there.

Having said that, having your dropper cable clogged up with dirt has nothing to do with frame design (except for the Transition reviewed yesterday). My bikes don't get dirty in the seat tube, but they do in the dropper lever. And if dirt gets in (which it does), the actuation will get worse with time.

So yeah, wireless and hydraulic actuated droppers can be superior products. Is it worth the money though? If you have money to spare, sure. If not, you'll be absolutely fine with a cable dropper.

Although this is going to date me or put me in a luddite category (and I'm plenty tech savvy), but going riding is my one chance it seems to truly unplug. No lights, buzzers, screens, batteries etc. Not that I don't see some functional benefit to some of these things, or the engineering elegance, but having to read another screen, dial, light, battery etc. while deep in the woods?

 Hearing you: also have zero desire for having e-anything, but can see the utility of e-droppers as I service my dropper every 4-6 weeks or so and its a bit of a pain in the ass. After 20-30+ services, its down to a science now, but the cable is the limiting factor & needs frequent replacement so an e-dropper seems more of a utility than e-derailleur (?)

Compounding things for me persoally is that I"m temporarily on Team Eeb (except for DH lift / truck service) as I cracked a knee this summer & wrecked some joint tissue that simply will not be pain free so assist is the only way I can get uphill right now... so without that I'm just an angry jerk on a stationary or trainer. That being said, I don't like biking knowing my battery can spend out back in the woods, cutting the day short b/c of a battery - or even having to charge it up w/ near daily rides. It feels limitiing and I find all I want to do is be able to ride the regular bike.

In once sense, given how many literally 100's of 1000's of actions in our lives are automated - this website, my laptop to chat with it, house lights, tires, fuel, manufacturing, modern food & distro, your cellphone...what's one more battery.
Yet the thought of even a battery (and battery & motor) irks me even tho its the only way I can get on most trails right now. But it still makes sense to minimize as much of that as you can. I feel ya. What to do - its a constant balancing act.

 I want to share a concern that many individual inventors face in our industry. It's disheartening when large corporations use ideas developed by smaller entities or individuals without proper recognition or compensation. In my specific case, I developed a particular design that is now being used by a well-known bike component manufacturer. I filed for a patent on this design back in 2020. While I understand that legal recourse can be challenging and costly for individuals like myself, I believe it's important to bring attention to these practices for the sake of ethical business conduct. I am hopeful for an amicable resolution and greater respect for intellectual property rights in our field.

 We are not "whining" as a few trolls have said. We are simply using a public forum to make people aware of the true situation. As a small company, it is difficult for us to go up against one as large as KS, but we will do our best.

To be clear, KS did not "copy" our design. They used our design exactly as we created it. The patent illustrations were created from 3D models that we own and created. The dispute is over their rights to use the design without our permission, and without KS fulfilling their contractual obligations.

 We at Cell Cycling, alongside our collaborator Paul Gallagher, wish to address the recent release of the KS wireless dropper. For two years, we worked diligently under contract with KS to bring this innovative design to life. However, in the latter stages, we noticed a lack of progress from KS, which led us to believe the project had stalled. To our surprise, we recently discovered that KS filed a patent in Taiwan on May 1, 2020, utilizing the design we developed. This came just two days before we filed our patent with the USPTO. Upon reviewing KS's patent documentation, it's clear that our original designs and models were used without modification. The issue of patent 'ownership' can be complex, but 'inventorship' is unequivocal. Paul Gallagher is the true inventor of this design, and we have extensive documentation, including thousands of CAD files, to support this claim. This situation has resulted in significant financial setbacks for us, and we intend to challenge this matter to ensure that intellectual property rights are honored and respected. We believe in fair and ethical business practices, and we're committed to standing up for these principles.
  • 5 1
 Sorry to hear this, sounds like it's been handled badly.

IP and patents is a complex matter in itself. A key question on ownership of IP is going to be weather you developed it while paid/contracted by them, or implemented something you had invented/designed previously. If developed during time paid by them, generally the IP is their. I.e.. an employee can't personally patent something done during work time, it belongs to employer (in the countries I know).

But I realize you know this already and there's more to this story. Hope it works out ok for you.

 Yep I'll ride plenty of trail sections with the seat down an inch or two or three because it's a mix of tech features where I want the maneuverability with seated pedaling sections in between. But I'm not so fussy as to go "dang I needed another 3.18mm of seat height for my optimal leg angle but this cable lever contraption is tooooooo much work" lol
  • 4 0
 @pakleni: I do a lot of technical climbing and find that a few mm down for the trickiest moves makes a big difference, at the expense of maximum pedalling efficiency. I think I adjust seat hight more often than I shift gears. No desire for wireless anything, though.

 Wireless Droppers if made good an reliable can benefit older frames that dont come with the internal routing, theres limited choice with external droppers these days when compared to whats available with internal droppers.

 I would suggest everyone be a little patient and wait for the Bikeyoke wireless dropper. Its not for me to say "when", but the release is immanent. It is substantially better than the KS model and has the very cool feature of looking exactly like a normal dropper. It will accommodate all saddles with no interference. No interference from the tire. And its all safely protected inside the tube. As for the price, I know as much as you guys do from reading the comments by Stefan. These guys are a class act. This is taking longer than the others because they are not compromising on the quality and performance. Its worth the wait.

 Honestly as far as dropper innovation goes the only things I really want to see is a quick release and adjust for the saddle to the post. Unless they can figure out how to not bury the schraeder valve under the seat which requires disassembly any time u want to air up your dropper. Maybe somewhere lower and out of the way, on the dropper body.......
  • 2 0
 I think I'd rather have the air valve on the top, rather than having to pull my post out every time I want to add air. Not really an issue with a wireless dropper, but if you run a cable-actuated dropper it can be a pain, especially with internal routing.
  • 2 0
 @zmcfadden28: I don't think you could have a dropper actuator and a valve at the bottom at the same time. So you should be safe there. On a wireless I'd much rather have the have the valve at the bottom and not have to take the seat off.

 I'm not for all those wireless/batteries/bluetooth things but would have loved a wireless dropper! I had 2 bikes in 2015-2017 that were pain in the ass to pass those cables! And now my Banshee Titan is even worse as the seatpost is always cracking as it gets all dirty in that every 2 weeks I could take it out and clean it!! Now its a twice a season thing as I have to take off the shock, then the cable with the foam doesn't want to move inside my downtube!! f*ck I just want that external cable routing like I have on my fatbike/had on my V1 Knolly Warden!! OR, this dropper post (I was waiting for the Bike Yoke one, next year). Anyway, too late for the party, after 2 years (3 but my XL I had first year wasn't noisy) of riding that noisy bike, I quit and will just buy a new one!

 If you happen to have grip related issues, and some of us do, ulnar nerve damage etc., the wireless dropper is a extremely important piece of kit, worth every penny. Instead of having to partially un grip and swing the thumb through a arc, just tap and never disturb your grip. Shifting is a similar situation, not as critical but then my right is less impaired. It is surprising that Sram hasn't put out a longer post, I'm sure it'll be here soon.

 From all the wireless dropper systems on the market, I think I prefer the Magura Vyron because it does not come with rechargeable batteries. It uses standard CR2 and a CR2032 batteries that you can just keep as spare in the back pack or in the car and keep riding without worrying about recharges.

 My least favorite thing about wireless droppers is the stack height. I replaced an AXS dropper that came stock on my old bike because I gained an extra 30mm+ by using a OneUp.

The thing I loved the most about that wireless dropper is that if I forgot to charge my derailleur battery (sadly, happened multiple times, never learned my lesson) I could swap it out with the seat post for the climb up
