Review: TranzX EDP01 Wireless Electronic Dropper Post

Sep 21, 2023

Wireless electronic dropper posts have been in existence since 2017, when Magura's Vyron post debuted. RockShox released their Reverb AXS dropper two years later, and in the years since it's become the most commonly seen housing-free option. There's just one problem – there's still no 200mm version, and no clear answers as to if / when we'll see one. That hole in the marketplace is slowly starting to fill with alternatives, including the TranzX EDP01 reviewed here.
EDP01 Dropper Details
• Travel amounts: 150, 170, 200mm (tested)
• 30.9 or 31.6mm diameters
• Weight: 767 grams / remote: 52 grams
• Two-year warranty
• MSRP: $499 USD (includes battery + remote)
• More info: na.tranzx.com

The EDP01 is available in 31.6 and 30.9mm diameters with either 150, 170, or 200mm of drop. The post is powered by a rechargeable 7.4 volt battery, and the remote uses a CR2032 battery. TranzX claims the post can be activated 6,000 times before needing a charge, although my fear of being stuck out on the trail with a non-functioning dropper caused me to charge it every handful of rides just to be safe.

INSTALLATION

There isn't any performance aspect of a wireless dropper post that makes it a must-have over a cable-actuated version, although the ease of installation does count for something. There's no cable and housing to deal with, and getting it up and running is as simple as putting the post in the frame, pairing it with the remote, and hitting the trail.

TranzX touts the post's short insertion depth, and while it is low at 290mm, the total length of the EDP01 from the bottom to the rails when fully extended is 545mm, while a 200mm OneUp dropper measures 530mm – the distance from the bottom of the collar to the seat rails is longer on the EDP01, due to the motorized mechanism. That means that to achieve the same seat height, the TranzX would need to be inserted further into a frame than the OneUp.

The post uses a one bolt design to clamp the seat into the rails, with another bolt at the front of the post that's used to adjust the seat angle. It's a convenient system, and I found it to be quicker to use than some of the more fiddly two-bolt options out there.

The remote comes with a standalone split clamp, and it's also compatible with SRAM's Matchmaker clamp design.

PERFORMANCE

Initially, the EDP01's return speed was on the slower side, that is until I increased the air pressure in the cartridge to 350 psi (the maximum recommended) via the air valve on the bottom of the post. That helped speed things up, and while it still doesn't extend as quickly as a RockShox AXS, that faster return rate was an improvement. The effort it takes to lower the seat is fairly average – it's not as silky smooth as a BikeYoke, for example, or even the aforementioned Reverb AXS.

The good news is that it didn't develop any squishiness during the test period – the cartridge is still going strong. TranzX also sells replacement cartridges separately, and should an issue arise they can be swapped out in a matter of minutes. They may look and function similarly, but TranzX is adamant that the cartridges are not manufactured by Wintek, the company that makes the internals for many other dropper posts.

The remote lever is easy to access, and while it may not be the most elegant looking component, I don't have any complaints about its functionality.

As for the run time of the post, I did have the battery die on me partway through a ride. I'd left the battery installed during a three-hour drive with my bike on a vertical hitch rack, and then forgot to check its status before my next ride. It's a good reminder to take the battery out when driving longer distances; otherwise the road vibrations can potentially cause it to constantly try to pair with the remote and run the battery down, at least I'm assuming that's what happened.

That was the only hiccup I experienced, although I'd be tempted to purchase a spare battery to bring along on mega-rides, just in case (they're available for $49 USD). It's wishful thinking, but it sure would have been nice if the EDP01 battery was compatible with SRAM's AXS batteries, and vice versa.

ISSUES

After a few months of use the post started making a knocking noise when the seat was lowered and I went over chattery sections of trail. I eventually narrowed it down to the nut that attaches to the cartridge at the base of the post. That had loosened slightly, and was allowing the cartridge to move up and down and make a racket. I snugged it down, and it's been smooth sailing since.

Pros

+ Very easy installation
+ No need to worry about cable routing or contaminated housing
+ Easy to disassemble for basic servicing

Cons

- Going wireless isn't cheap
- Not the fastest return speed
- Heavier than cable-actuated posts, even when factoring in the weight of cable + housing




Pinkbike's Take


bigquotesFor riders dead set on a wireless dropper, the EDP01 could fit the bill. It's still more expensive (and heavier) than the sea of fully functional cable-actuated options out there, but it's also not as pricey as a RockShox Reverb AXS, and it's available with 200mm of drop. I am glad of its existence, mainly for the ease that I can install it when a review bike inevitably arrives with a dropper that's too short. That said, I'm not entirely convinced that needing to remember to charge a battery is worth the tradeoff for a cleaner-looking cockpit.— Mike Kazimer

 If you've ever had a dropper fail on a ride, it can be a pretty dramatic fail, so adding in a battery which increases the potential for failing is not my idea of a good time. Good luck with all your electronic doodads, I'm good with mechanical stuff.
  • 231 60
 If your battery isn't charged that's not the post failing, that's you failing. If you can charge a cell phone battery every day you can charge a dropper post battery once a month.
  • 60 31
 But you are removing cables and housings that can fail. 6 of one, half dozen of the other I suppose. I've had mechanical droppers fail on me multiple times. I've yet to have my AXS have any issues. On long rides I have a pack too, so putting a 20g battery as an extra isn't the end of the world, however, I've yet to have the thing die on me with reasonable charging schedule. aka once every couple of weeks regardless if I see a red light.
  • 59 29
 @warmerdamj: you’ve clearly not worked on enough AXS equipped bikes to know the contacts on the batteries fail, and the derailleurs, Flight Attendant modules, and seatposts can go braindead and need full replacement. On top of that, unlike a mechanical part that can usually be Macgyvered enough with a multitool and zip ties to keep you going, the electronic stuff often ends up being stuck in position which sucks if you’re way out there or on a trip without credible shop nearby.

 @nation: I've had AXS posts and drivetrains for years but you're right I've never worked on them. Because they've never needed work. The stuff is solid and I'm sure this post is too.

 @nation: exactly right. I had this exact thing happen to me at Trestles Bike park—long story, but I had a mechanical dropped fail on me and was able to rig up a method to make it work well enough not to mess up my day. If a control module, wire, batter lead, etc. craps out mid ride there’s nothing you can do.

 Been 4 years now, never had Axs fail… but enjoy what you will.

 @bmied31: even easier, if you also have AXS drivetrain, in a pinch when you screwed up and failed to charge a battery, you can shift the battery back and forth as needed to get home.

 Yeah, I don't get the angst over batteries at all. It's just another thing that needs some form of maintenance just like every other part of the bike. It has failure modes and failure rates like everything else. Whether it's mechanical, electrical, chemical, or wizard magic makes little difference to me.

 @sanchofula Did all of these e-Apologists miss the part where this hot e-Garbage post fails *during the drive to the trailhead*? Are toy fetishists in this sport really that desperate to have their wallets emptied by e-Pimps? The mind boggles...

 @warmerdamj: great point - that's two extra modes of failure, then.

 one of the bigger reasons i can see to use this (along with 200mm drop) would be to avoid headset cable routing. This plus axs shifting, and you could reroute a brake line externally and be done with cables and headset routing.
  • 38 7
 Are you guys really pretending you had a dropper cable or housing fail? Or that's even close to the likelihood of a battery losing charge or the seal that you're opening every day to charge your battery leaking?

And you couldn't figure out a way to move your post to get home after your cable "failed"? Really? That's what you're claiming happens to you regularly enough to justify spending more than 2x the price of any cable post?

 @Weens: my current bike let's water down the seat tube. So since May I've replaced the housing 3 times and cable about 5, it also seized once. So while I'm sure I'm in the minority to have a crappy manufacturing tolerance on my frame a wireless post would fix this problem
  • 5 1
 @DustOnCrust: yeah, it's a bit of a disaster if any time the bike moves it wakes the battery powered everything, somehow draining the battery (but just Bluetooth pairing shouldn't exactly use energy compared to moving mechanical bits, so frankly, can't see how it got drained). Would be really useful if there was a little cable you could use to just suck a few joules out of a phone battery to get enough juice to get you home

 Pretty easy to carry a spare cable, too. Weighs nothing and coils up small. I’ve carried one for years and never needed it, but should be able to swap a broken dropper or derailleur cable out in about 5 minutes trailside if needed

I have some AXS shifting and droppers, some completely mechanical, and some a mix of AXS shifting and mechanical droppers. AXS droppers are the best I have ever used, two quick taps and it drops 10mm for better tech climbing, brilliant. I change batteries every few rides and carry a couple with me mostly for my kid that never charges his... never had an issue. I don't understand the "back in my day" attitude either. Buy it or don't, hope he has fun with his Model T.

 Wow, lots of replies Smile

I guess I just don't get the "thneed" for certain things, so I totally get wanting a long dropper, I run 200+ on all my bikes, but it's hard to justify something when what you have works well.

Have I ever broken a cable, yeah, like once on a dropper and I got home fine cuz I know how to operate it without a cable.

But to take a dropper post which is already a potential weak leak (failed cartridges happen), then add a second weak leak, AND make it weigh a bunch more, wow, I just gotta wonder what folks are thinking.

I have a dropper and a QR binder so I can tweak it up or down, so simple, not much different from the days when a QR binder was your dropper.

You guys with your doodads are kinda wierd, like Strava users, it's the "keeping up with the Joneses" that allows manufacturers to keep selling us the goods, and you guys are driving this market.

How about putting your energies into something worthy, like a gearbox? Talk about beneficial and low maintenance, only cost is initial expense and the weight ... and if you use an electric dropper then clearly you don't care about that )
  • 3 2
 @sanchofula: Gearboxes are cool too, few companies working on those - even wireless shifting versions - just like companies that are making wireless components. Imagine that, we can have both.

Waiting for a rigid single speed rider without a dropper to swoop in here and complain about your "gears and dropper post doodads..."

 @bmied31: If this is what you're worried about, you should have spent the extra dollars on a Revive rather than an electronic dropper. Bikeyoke very unlikely to have issues, and if there is a cable issue, you can easily let it up and down with a 4mm allen key and the bleed functionality. And you'd get to enjoy the sublime action the 99.99999 . . . % of the time there is no issue with the housing and cable.

Buy electronic if you like, but not sure it dresses up well as a practical purchase.

 @briain: my Capra let water in and caused the actuator on my oneup to seize. I replaced the cable but first sprayed a ton of WD-40 silicone spray into the housing then fed the cable through. Cleaned up the actuator so it was smooth again and gave it a good bath with the same silicone spray. Lasted for another year and a half no issues, moved the dropper over to my la sal and still running a year later. Not guaranteed to work for you, but maybe something worth trying.

 @warmerdamj: I hear you but as an owner of Fox live valve I can attest charging a phone nightly is easy but remembering to charge the bike which may need it anywhere from 2-6 weeks apart is near impossible. The upside for me is it still works ok if the battery dies but the same could not be said for a failing dropper. I wouldn't buy electronic suspension again but I got a killer deal on the bike and figured why not try it.

 @sanchofula: my feeling is there should always be a backup "get you home" option on these things. A mechanical mech has a couple of bodge options. A cable seatpost can be operated by hand/tool where the cable goes in (would get tedious, but would be fine for race stages etc). Pretty sure a Reverb can't be operated without a remote - I managed to pull the hose out in a crash, fortunately with the post down. I was at a race where the guy in front of me managed to somehow knock his AXS remote off, I think in a fall. Not going to find that again, and would have been a looong way with no way of operating the post

 You can check a battery status with a button press (AXS Reverb anyway) - how easy is it for you to check your cable condition?
Regularly 40 hours riding with the Reverb before hitting the 'low' battery warning. As @warmerdamj says if you can manage a cell phone you can manage AXS and it is by far the best dropper I have ever used (equal to BikeYoke and 9pointCool .

Not sure we'll ever get a gearbox for the masses because the main players make money from new mechs, hangers, shifters etc every few years. It's one of the few old school things that probably could be improved, but isn't.

 The thing is, as I'm sure others have pointed out, that running out of battery power on a wireless post mid-ride is as easy as swapping out the battery for a freshie, whereas a cable snapping or getting kinked can be the end of that post's functionality for the whole ride. I doubt you'd be swapping out a dropper cable on the side of the trail.

 I agree. I've had a Reverb AXS for about a week (came with my new bike). It's a nice dropper, but I don't see any tangible benefit over a traditional dropper, apart from setup (which I didn't have to do). After a few rides, I came to the same conclusion as you--I might be willing to pay up to $100 extra for the wireless, but nothing more.

The more I ride them side by side the more I think AXS is ok. I didn’t like it at first. It took all of BCBike Race plus 700km to get a good understanding of how it is different/better/worse.

My wife has a Repeater with headset routing, which sucks on it's own. When she turned left, slightly sharp, it'd activate the dropper and the seat would go up. She ate shit hard descending a trail up at Sun Peaks because the saddle popped up. when she crashed the cable ripped out from the bottom of the dropper and busted the mech on the bottom so it was stuck up. I had to take the saddle off and purge all the air so she could get back. Not say a wireless one wouldn't have its risks but dude cables activating stuff can suck.

 @daugherd: What are you running? My PNW droppers have been incredibly reliable. I did have an actuator back out once and it got stuck in the low position, but it took 2 minutes to fix. That trip was also an incredibly abusive whistler weekend that saw a broken shifter cable, a backed out thru axle (?????), and a shock body unthread itself. I've seen the cables rust, which is one of the reasons it isn't a good idea to spray them with a hose.

My reverb was garbage and my non-cartridge 9.8 was not great but my coil sprung PNW droppers have been dead reliable. I just grease every few months, which takes all of 1 minute.

 @CobyCobie:
I have a fox transfer, Bike Yoke, YT Postman and a PNW on my bikes and my wife have OneUp on both her mtbs.

Fox failed in Golden, lever broke, so not a post failure but it was the shit fox transfer lever
YT most recently got stuck down
PNW had bad seals and would sag.
Wifes OneUp was the one that broke in Sun Peaks.

The only one a wireless dopper would have been good would have been my wives here. I just tend to have shot luck with these things. Oddly my old KS Lev with external routing never had a single issue.

All have been fix with the exception of the YT because it’s on my capra. Oldly the YT had the best feel.

 I'd be a lot more tempted if they could make it compatible with the AXS batteries I already have. The last thing I need is Yet Another Battery System. AXS for me has hit a sweet spot with size, longevity, and with AXS on a couple bikes already I already have a spare.

 Dropper post have come a long way since I first introduced them in 2001 (Hurricane Elevator Shaft) where the first models had indexed drops within 75mm of total drop, accessed by a pull knob on the shaft to raise/ lower it. Our later and last version had a lever on the handlebar similar to current designs.
I love seeing all the advancements and appreciate that companies are not resting on just cable( or hydraulic) activation.
  • 8 0
 I have no idea why companies continue to put the battery behind the seat. Plenty of realestate in front, and you gain more tire clearance. Some sized bikes already rub the seats at full compression.

 @briain: Seth from Berm Peak/Bike Hacks did the same thing. Due to his height he was having an issue on his Revel bike where the rear tire would make contact with the battery and pop it right off. He rigged it so he could have it in the front of the post. It was a hackjob though.

 I honestly see an electric dropper in my future from the stand point of I have young kids and being able to pull the post out quickly to install or remove a tag along adaptor quickly. I don't want to have the adaptor on all the time and its kinda a pain the in the arse always disconnecting everything to pull the post to install the adaptor.
  • 2 0
 Tag along adapter on a dropper post seems like it's asking for problems. Removing and using a dedicated rigid post seems like a better idea and I have done that in the past and a wireless dropper would make easier

  • 5 0
 I use one on my Specialized bike as it's the only way to get the post 'almost' fully inserted. The internal cable routing causes an extra inch below a normal post. More of a negative on Specialized bikes than a plus for e-droppers but they offer a good solution.
  • 22 18
 I would argue there is absolutely a performance advantage from a wireless dropper over a cable actuated one. Cables get dirty, they stretch and can start to give resistance to the lever. Remote droppers avoid all this. And in regards to a regular reverb they eliminate the housing full of fluid which gives more opportunity to get air in there. Remote droppers are honestly just so much better and it's great to see more options.
  • 17 12
 That’s not performance, that’s maintenance (or lack thereof)

 @notthatfast: It is maintenance too, but when your lever starts to feel like shit it's performance imo.

 I think most people can agree that a quick-release seatpost clamp with a rigid post would be a better option than a hydraulic Reverb. So if that's all AXS has to compete against, the bar is low.

 And when my mechanical dropper fails, i can service it myself. When any of this wireless sh*t fails all you can do is sit there and stare at it.

  • 16 6
 Y'all are on something, as an electrical engineer who works on consumer electronics the last thing I was in my dropper is a circuit board and motor as additional failure points.

A dirty housing isn't going to leave you with a stuck high dropper on the trail, but a blown IC or fried motor definitely will. And if you think the long term reliability of a brushed motor and plastic gearbox is higher than that of a Bowden tube (shifter housing) then I'd just straight up disagree.

Patches, bugs, and glitches are things I don't want to bother with.

That's also fine and it's not a condemnation on anyone's choice to accept AXS into their life, so take solace in that.

In my experience when it comes to tech, nothing seems to works right without a fight. Every patch has a patch to fix the bugs in the previous patch. Daily life is over complicated enough by tech that supposed to make our lives better. How anyone would want an app to ride their bike is beyond me.

> Cables get dirty, they stretch and can start to give resistance to the lever.

Cables do not get dirty. I don't know which cable actuated droppers you have used but mine has full housing from the lever all the way to the dropper. There is no room for dirt to enter.

Cable do stretch mostly at the beginning of their life...and that is what barrel adjusters are for. You typically only use them once a few days after installation and...that's it. I can't recall the last time I had to adjust the cable tension, I think it was + 3years ago.

Cables do age and get corroded as do housing but it literally takes years, especially for a fully routed cable. It is not like the exposed derailleur cable of an old road bike. The cable on my dropper is I think 4 year old.

Still my overarching opinion about electronics and batteries on MTBs in general.

[I've ridden AXS and it's really good... so I'm glad it's out there for folks who want it. But I still prefer cheaper and simpler mechanical solutions on my personal bikes]

 Been running one since June and never had a problem with the battery. My battery actually seems to hold a charge longer than my SRAM AXS battery. I probably charge it once every 20 hours of riding and have never had it run out of juice. Like Kaz mentioned, it's a bit slow to extend, but think a dropper's ability to compress is more important than it's extension speed. I have a Fox Transfer on my other bike and the KLUNK sound it makes along with the speed is impressive, but I haven't noticed it being that advantageous over the Trans X. For the price, it's a great dropper and keeps your bars clean. I hate internal routing, so it was a no-brainer. I've had a Reverb AXS on my old bike and couldn't justify the price difference for recreational riding.

 i'm not even sure a battery operated dropper is what most people need.

just from the comments it would be rad if mechanical droppers had a secondary (manual) means of operating the dropper, say, a lever under the seat if the main mechanism failed, or cable broke.

 If it did fail on a ride if you let all of the air out of the canister would the post just stay down? Could you then just pump it up with air to make it extend again? Lots of faffing about but just wondering if that would be a solution if needed.
  • 1 0
 No, the air provides the spring to extend the post. The oil inside acts like locking out your fork. When you activate a dropper, mechanical or electronic, you're opening a path for that oil to flow when you sit on the saddle. When you release the actuator, the oil path closes and the dropper is locked out again. So to answer your question, if you let the air out, you would still have no way to actuate the oil flow gate and you would still not be able to change the saddle's height.

 Target audience: Cable tourists. It's the tail wagging the dog but if I have to drop my motor and remove my battery just to reposition my seatpost by God I'm ditching the bike or looking at wireless option. I'm looking at you Orbea Wild 2023. Absolute shit cable tourism.
  • 2 1
 Another plus of wireless is for travel. The ability to pull the whole post out quickly and easily and not have to worry about the cable disappearing inside the frame. Bonus is that if your bike and bag is pushing the weight limit, its easy enough to shove the post and saddle in your carry on. Price is still a bit of an issue - but non-wireless posts have been edging upwards so the gap is narrowing. I suspect at some point in the future, like drivetrains, there won't be cable options....

 Running cable and housing for a dropper is a huge pain in the ass in some frames, so I kinda get it, but I think this is one of those "the cure is worse than the disease" times.

Bike Yoke Revive = ~$350
Get a bike shop to install it for you = $100 at most

So, for $50 LESS, you get a smoother dropper, less stack height, easy post recharging, zero battery recharging needed, and a zero-hassle install (because you're not doing it yourself). I guess you might be in for slightly more maintenance in the future but as long as there's cable/housing in the frame already, replacing it is really not bad.
  • 1 1
 @charliewentoutside: I like my BikeYoke fine, but the clamp on the lever isn't the greatest. I had issues with it pulling out of the mounting point. Mostly the fault of the shop that assembled bike, but it's not a great design. Also sucks that the Allen bolt is smaller than every other one on my bike and only some multi-tools have an Allen that small. I'm carrying a separate single Allen just for that dumb bolt.

 I'd have to agree with a bunch of other comments in this thread. I'd be willing to pay $100 for the wireless upgrade. But double the price when comparing apples to apples (Reverb vs AXS or standard Tranz X vs this post). I just don't see where it's worth that kind of money.
