My Wireless Seatpost has a big problem... Let's hack it!

Dipublikasikan tanggal 13 Agu 2022
I love my Rockshox Reverb AXS dropper post. It’s solid, works quickly, looks good, and is operated wirelessly. I’m unwilling to use another dropper post, especially one with a cable release, but it’s starting to look like a good idea. The battery in the back of the Reverb hits into my tire when the rear suspension compresses all the way. Today, we’ll seek a solution for this issue.

  • For a $800 accessory, that's a major design flaw. Hopefully the manufacturers are taking note

    • @Only Fool Riding Did you at least watch the video? He literally demonstrated it can happen with air in the shock.

    • I would expect such design flaws with SRAM.

    • @S.K.H. there's already a lot of other stuff inside a dropper post

    • @Brian Wright I sell aftermarket parts for another hobby. You have to be as transparent as possible, test as many combinations as possible, and take feedback given. If we were told about an issue like this, we would add a warning to the product page about compatibility issues (we have done this in the past when new products came out that were incompatible with our parts or needed extra bits to make them compatible). My company has me working 5-10 hours a week, and a part time employee working about the same, yet we manage to do it, why can't they?

  • If there was ever a project to justify adding a 3D printer to your "tool box", I think this was it.

    • DOOOO IIIIIITTTT!!!!! I use mine for so much shit. I make stuff for everything now.

    • We'd never get him back. Don't do it Seth. Tie yourself to the mast and resist the siren's song

    • Seems like the natural progression for his ID-tv and mountain biking career. The content value alone would pay for it. I can see a whole new series based on experimental 3D bike parts, maybe even another whole channel

    • @Michael Summer Yeah, I got myself that bigger Prusa and for casual tinkering, it serves well...

    • @Beno C ...such is a powerwasher, leafblower, chainsaw... Should I continue? :-)

  • This is the first time someone has been truthful with a axs dropper. Everyone else, it's perfect just perfect. Thank you Seth. One-up components for the win. Stick with the basics

    • I prefer Bikeyoke.

    • my oneup aint as smooth, needs regreasing often & the seal is crap... rather have a fox transfer honestly

    • it's good product everyone, if you can't afford it just dont drag people along with you. like seth some people can afford to hack it using a hack saw. but if you cant use a hacksaw on it dont buy it. mtb should not be treated like a baby, but rather like a slave to take all the beatings.

    • @クラウドシルバー For you it's not perfect and is overrated, for many others it is indeed perfect for their needs. But hey, the world revolves around you, right?

    • @クラウドシルバー .period. dot...dot...dot..., you see what I mean?

  • I always enjoy Seth's content regardless of what he is doing, however, when I saw him break out the hacksaw I genuinely tensed up and said out loud "Oh no...don't do it"

    • me too, I was like put the saddle on backwards first, verify this for me.... noooooo its cut

    • “No don’t do it, I’m a virgin!”

  • Seth, SRAM should send you a check for doing their R&D, or at minimum, a new post, free of charge, when they inevitably take inspiration from what you just did!

  • The escalation from calm to hacksaw was faster than I expected

    • That escalated quickly.

    • @Repent and believe in Jesus Christ take your invisible friend somewhere else...

    • I take it you don't know Jeremy Clarkson who starts with a hammer.

    • ability to have kids? OVERRATED. HACK. THAT. SEATPOST!!!

    • Hack saw is plan B, Oxyaxcytelene is I'm not asking anything 🤣

  • I've known about this problem since last year. I can't believe companies release a product like this without testing it first, it's a pretty basic flaw. I have 2 friends who regularly knock the battery off with their rear tire when bottoming out. WTF.

  • That was intense, the emotional involvement. I feel you, stuff like that has happened to me a lot. Thanks for showing us that hacks can go wrong, and may end up frustrating you. That's part of tinkering with stuff, but usually failure means learning. Maybe you'll wake up one morning with a perfect solution for this. Then, the feeling of accomplishment will be even greater than the current frustration.

  • I approve of the remote battery hack! I know Seth ended up just hacking off the seat post, but for anyone else: make sure the battery has some Armor against meteorites flying off the rear tire. If you pierce a flat battery pack they do tend to shoot flames.

  • This video was pure gold start to finish. From the time it took to go from sane to hack saw was about the time of my patience level. Totally relatable!

  • Only Seth would mess with a $800 dropper post😂 Your content is great Seth, keep it up!

    • @Piotrek I'm guilty of that shit, too. And I mostly regret it ;D

    • He has the money to buy A LOT of wireless dropper posts before it really hits home LOL

    • @Lou Sassle he got the bike for free he probably got the dropper for free too.

  • Combine both of your solutions - turn seatpost around AND use that adaptor - in that way you can't hit it with tire AND you can still make bigger family 🙂

    • @R C but the battery was impacting the tires not the seat

    • I think turning the post around would limit the seat from pointing low enough.

    • @Beno C You are correct. I have the RockShox AXS seat post as well and it's the seat post itself that sticks up and is hitting his seat. Anyone can google image search the seat post and see. Seth probably should have shown a close up though because I can understand how some viewers are confused. While I agree with Seth that this probably could have been designed better, it would only affect some brands of bikes and only the ones with Small frames which he alluded to but didn't quite spell out. All in all it's a great seat post and blows away any wired dropper post but it does have two major cons: 1) The price - it's way too expensive for what it is even though I love it, and 2) They apparently aren't manufacturing the (overpriced) 200 & 600 hour service kits. I've been on notify lists on various websites for almost a year and haven't heard anything. Any time I have manually checked they've been out of stock.

    • @Beno C it was the battery

    • I don't think it was the battery that was impacting the seat or he would have done that.

  • This is amazing. "The 6 of you" joke was perfectly delivered, but I also love seeing the reverse engineering that went into this.

  • I always enjoy Seth's content regardless of what he is doing, however, when I saw him break out the hacksaw I genuinely tensed up and said out loud "Oh no...don't do it"

  • I always enjoy Seth's content regardless of what he is doing, however, when I saw him break out the hacksaw I genuinely tensed up and said out loud "Oh no...don't do it"

  • There's just no way. I wish people wouldn't pay outrageous prices for things just to say they have it. So it's worth 600 dollars to not have a cable but have to keep up with a battery?...I can't see it. That being said love the channel keep up the good work!

    • The early adopters will happily pay a lot of money for the new tech. Normal people like us will benefit from them paying “outrageous” prices when the product first hits the market, because the early adopters make the product market viable and the manufacturer then increases production, and other companies take note and make their own versions… all of which leads to lower prices. If nobody bought these AXS droppers now the tech would probably die and never take off.

    • Its the early adopter fee. Any new tech always costs more because its not mass produced. I already think 200 for a dropper is crazy cuz its just a hydrolic tube but theyre way cheaper than when they were first released

  • This is why I started watching Seth's bike hacks back in the day I love this type of content

  • I feel like the biking industry is the only industry that tries to justify a 4x mark up on a part because it's wireless.

    • @one word Someone also had to run R&D on the product including testing, develop it and bring it to manufacturing as a whole new product. Prices are set based on how much they've spent on it and how many they're expecting to sell. They overcharge for the battery but that's about it.

    • @Kevin Templeton Yes but how many sales do they make based on a particular price? For example let’s say this wireless dropper cost $200 to manufacture they sell it for $800 that’s $600 profit per sale (obviously I’m handwaving away shipping and warehousing and advertising and all that bullshit for the sake of simplistic explanation) so at $800 a pop say they sell 10,000 seat posts that’s a profit of $6 million BUT if they drop the price to $400 while they’re only making $200 profit per seat post they may be able to sell 100,000 unity, generating $20 million in profit

    • Manufacturers have no need to justify what they sell, they just need to make sales. The customers justify the markup by buying the product despite it.

    • @PastaJuice Fair, but if they weren’t marking it up so goddamn much there would be much higher demand

    • @Vytautas what do you think?

  • I have this exact same problem when g-ing out. Love this dropper, but really hope SRAM moves or redesigns the battery on v2. Had to raise my seat to keep it from happening.

  • I've seen other people complaining that their saddle would hit the wheel if they used a dropper too low (and long). Not a problem for me, a hardtail (poor) rider.

  • You could try using a saddle with a central cut out, that might give enough clearance to adjust the saddle without getting that hump.

  • Thanks Seth for going the extra mile. I ride a size small and go for a 150mm dropper so pointing out that flaw does highlight the cons since I'm considering getting one. As for your battery hack, I think you can get away with replicating the pads with a PCB and 3d printing the rest including a separate enclosure for your battery that is secured to your seat instead of the dual-lock.

  • I think Rockshox should pay Seth for giving them an idea to make their wireless dropper post better.

    • @Esteban Gonzalez It's the same company, and it's literally a *RockShox* Reverb.

    • Include a hacksaw with the dropper? 😉

    • @Esteban Gonzalez same company

    • That’s sram

  • I work an an Industrial Automation Electrician, and I can say confidently, that things being unnecessarily automated or electronically controlled, is hardly ever better. BUT it keeps jobs around for me, because people continue to do it, and it always fails! 😂

    • The electronic derailleur everyone who uses does not go back to cable, as the electronic has automatic derailleur hanger misalignment correction is a significant advance. Seth has a goal of testing products to the extreme and doing various tests, for him the videos generate profit and usually pay the damage, for the manufacturers is the tip of changing the battery position. And I really don't have a wireless Seatpost to give an opinion on this product, but the derailleur I have to admit that there's no way to go back to using cables after him.

    • @end I understand that, but the point I was making was… is removing a simple, and reliable cable for an expensive, bulky, and battery powered part that requires charging really worth it? In Seth’s case, it looks like it created a bigger problem than any problems or nuisances it may have solved.

    • in this case the idea is to remove the cable, the mistake is not thinking about the sag of the dampers, and the design mistake was not putting the battery in front

  • I love this, so many times I've been down similar roads in my workshop. I feel you Seth.

  • Pretty cool, I love hacks like this! But please be super careful when hacking into LiPo/LiIon Batteries. If damaged they burst into flames very violently. This better be done outside with nothing flamable around.

  • You had me laughing so hard. I loved watching this process and can totally identify with you. Thanks for bringing up an issue with the wireless droppers. I have been thinking of getting one at some point. Hopefully this will get reengineered before I pull the trigger!

  • That seems like a lot of work just to avoid having a wired dropper post.

  • That adapter looks so good. It looks like you bought it. Congratulations man. You did an amazing job. Making it look like you got it from a store is (for me at least) the hallmark of good diy. Too bad it didn't work 😕.

  • The part where you said “I know you don’t feel bad” and “the six of you that have this problem as well” were golden dude

  • Great job Seth , Your reverse engineering never fails. Ps: Fun problem to have lol .....😃

  • Love it, "For the six of you that have this problem..." Great video, as always!

  • Love to see a modern generator solution. Make your own power pedaling or wheels spinning.

  • I feel like there still may be a solution in the original approach. Otherwise, I wonder if you had a saddle with a wide opening in it like the Specialized Mimic. if it wouldn't matter that the post was a little higher when mounted backwards.

  • Make sure you've kept the battery management circuit, lipo batteries like to get angry if they're over or undercharged

  • 6 years ago he had a basic hard-tail and he didn't want more. Look at him now😁

    • 😂😂😂

    • @BermChasin' But a 2k Pc will salp your balls off at anything compared to an m1 or m2 chipped mac. The M-chip might be strong but for the money every thing else lacks, the ram, the gpu, the cooling and the upgradeability/ repairability.

    • @Kermit Of War No reason for them not to be overpriced. People will buy them anyways, because it's hobby - things we love. And company's owners know that.

  • Funny, as soon as I saw the battery sticking off the back in their pictures, I knew something wasn't going to be right. Hopefully a version 2.0 will be forthcoming with a new design. And probably $1200. Sigh.

  • I was so impressed with how you engineered a solution to a problem and I felt your pain when it didn't work.

  • Seth's car audio days still paying off! Pretty damn impressive!

  • Love the video!!! They do make slim profile batteries I found them on Amazon and they are pretty much the same and I have been using them for a few months now and no issues I think a 2 pack go for 35 bucks

  • love seeing these kind of videos where you apply non-bike knowledge to problems like this one, greetings from chile!

    • Oh sick! I just skied Valle Nevado and El Colorado a few days ago 🤙

    • Santiago Chile here. Originally from Kansas

  • I love that you make everything as relatable as possible but I cant help but start the '3D printer' chant!! This would definitely be the perfect project for it!

  • I always enjoy Seth's content regardless of what he is doing, however, when I saw him break out the hacksaw I genuinely tensed up and said out loud "Oh no...don't do it"

  • Only Seth would mess with a $800 dropper post😂 Your content is great Seth, keep it up!

  • I like that you went straight into hacking it to pieces instead of getting longer seat rail clamps made for the thing

  • this probably only happens on a SMALL size bike. But the solution was absolutely brilliant.

  • Man I've been on the fence for getting with those for a while. I did the axs shifters and absolutely love them. Really tough to swallow $800 for a seat post.

    • The people here locally LOVE that post, and have stated that they would forego the drivetrain for the post if given a choice of one or the other. I don't know anyone who has one and has said anything negative about it.

    • Congratulations you have been selected among our shortlisted winners 🎁🎁 Telegram the above username so we can sort this out.🎁

  • Depending on your crank length, you could shorten them up to gain more clearance (seat post height goes up).

  • If it is the actual battery pushing on the underside of the seat, combine the two solutions. And then make it waterproof 👍🏻

  • LOL. This is a great video! I would definitely hack the seat by welding some additional rails to it, to make it sit up another cm or so... Alternatively, you could just not drop your seat all the way, and leave a cm of clearance...

  • You could 3D print a little housing for the adaptor that could look really flush and cool on top of being weather tight

  • This seems like a good opportunity to utilize the 3D printer!

  • Great video Seth! I love the simple solution to a unique problem

  • This was super cool Seth! You definitely need to do more videos like this!!!

  • wireless technology is so ubiquitous and cheap these days. their profit margin on the Reverb has gotta be absolutely insane... really surprised there are not more options out there from other companies yet

  • First ever bodge to be seen on this channel 😅 But probably still better than the original design it seems! Way to go! And I am sure you‘ll find an even better solution soon 😃

  • This is amazing. "The 6 of you" joke was perfectly delivered, but I also love seeing the reverse engineering that went into this.

  • Seth is literally me working on a bike I mess one thing up and then a next until the part is broken. But Seth is also a great bike mechanic.

  • While I know the end goal didn’t happen the way you wanted, I’m still insanely impressed with how you got there. Your intelligence is way beyond most

  • I have the same personality flaw, among others! :) Could you do both solutions at once? Or does moving the battery (again) not reduce how much the whole thing sticks up into your seat? I think the next step might be to go back to your initial hack, but then add some type of casing/protection to the battery contact so that when the wheel hits it, it can't be yoinked out of place......shrink wrap it with a plastic soda bottle and heat gun?

  • Wouldn't the combination of the two hacks be what you were looking for? Seatpost turned and hacked battery - loads of tyre clearance and no hump under the saddle

  • Great work Seth! Appreciate you trying out such crazy ideas🤣

  • You should just make a skid plate behind the battery like on the back of the Concorde. Or a wheel that the back tire rubs against connected to the seat

  • If there was ever a project to justify adding a 3D printer to your "tool box", I think this was it.

  • "For the 6 of you that have this problem as well." - Im dying. I love you Berm Peak. Im just a casual rider and I cant cant enough of your problem videos even though I will probably never experience them lol.

  • So these little clamps that hold the seat rails... Could those be extended somehow? Edit: Or you could pull the rails from the seat and make 'taller' ones so it clears when you reverse it.

    • @Dulmi thx.

    • @Vytautas definitely spam. all over youtube on all sorts of big channels

    • @sjeants better safe than sorry :)

    • @Berm Peak Express - same here but you know no one trusts anything anymore. Interest to see if this is actually true

    • @Berm Peak Express do you do some kind of giveaways or i just have been tricked? By the same name channel wrote me to keep in touch in telegram

  • This channel has come so far. Look at us learning about basic DC circuits and soldering!

  • You could try and customize the mount on the saddle to give you more clearance

  • I think you were headed down the right path with the first redesign, but I have the same "fu-- it, I'll make it work" attitude that you do and would have ended up with the hack saw as well.

  • That is absolutely ridiculous that they wouldn't engineer it differently for full rear suspension movement. Not really a hard fix as Seth has just shown us, just run a remote battery via wires under the seat.

  • The torx screw that tilts the saddle looks like it would back straight out with the right pin spanner to remove the lock with no need for a hacksaw. Needs to be revisited for am update!

  • The escalation from calm to hacksaw was faster than I expected

  • The escalation from calm to hacksaw was faster than I expected

  • As a fellow short guy on small frames I feel your pain with droppers. Even with normal droppers often the bends in the seat tubes make it hard to run much more than a 125mm dropper on the smalls and get the right seat height.

    • @david doornenbal already got one, doesn't entirely make up for most frame designs though.

    • Then you should buy a oneup dropper, they are the shortest droppers excisting

  • the return of "Seth's bike hack's", diy for life

  • My only concern is that the LiPo (which I recognize as being from an SCX24 if I'm not mistaken, and is a 2-cell battery) will either a) become unbalanced over time, and b) will over-discharge beyond repair, since there's no speed controller with low voltage protection. If you added a low-voltage alarm to the balance connector, it would beep when voltage dropped too low, so you would know to recharge it. That would work.

  • You could 3d print a super thin plate to connect the seat post terminals to the battery, or you could solder wires to the terminals then run them to the location of the taped battery which would be even slimmer than the printed plate.

    • @SILENT MINORITY cope harder, you're just mad people can make self-defense "tools" with them

    • @SILENT MINORITY quite the opposite actually, they squeeze material out

    • 3d printers suck

    • Exactly. Even better he can print a bumper for the Ergon saddle so that the saddle makes the first contact, not the slim adapter.

  • Great vid, super entertaining. I'd love to run that dropper, but it's too short for me....😭

  • this would have been a perfect project for the 3d printer. You could easily design an adapter in a simple CAD program that would not protrude at all from the battery port, and print it in PETG OR abs.

  • Hey Seth maybe since your are no longer partnered with any specific brand and have a company that can make custom fabricated components for bikes. Maybe they could make a custom saddle rail that has a bigger rise than normal so the mechanism isn’t pushing against the seat

  • Maybe an opportunity to collab with Wheels Mfg again? They're amazing at solving weird problems like this, maybe they can create a new clamp with additional clearance that allows folks to flip their dropper post around like you did?

  • This video was pure gold start to finish. From the time it took to go from sane to hack saw was about the time of my patience level. Totally relatable!

  • Love it!! I will say this though. If that lipo is a soft-sided RC battery it'll react poorly to having and holes poked in it.

  • I find the second version better: you could cutout the part of the saddle which is in interference and be good to go.

  • That’s a pretty big miss by the product designers. Nonetheless, I like the solution. I’m a “meh” bike mechanic, but I’m pretty good at wiring stuff like that. It’s all part of being an Extra Class Ham. I love shrink tubing. Too bad it wasn’t a perfect solution.

  • "I cannot stress enough how much this is not a tutorial." - Seth (many times but, weirdly, not this time...)

  • I feel you pain - 5’6” with a 29” inseam. Droppers have been the Bain of my existence, 29ers even more so. Not from a riding perspective but continually buzzing my butt when landing jumps. I now just keep to 27.5

  • As with all new to market products the manufacturer will hold some features/design back for v2.0, v3.0 etc. I bet they already have this sorted in the pipeline for the next version, to make us buy the new one! Also, I don’t understand why they don’t combine the post control into the shifter, that would get the cockpit even cleaner. Maybe that’s coming! Love the vids 👍🏻!

  • Thank you Seth! Been struggling with that battery issue too but now I have an idea of what to do. Once I'm able to upgrade my $100 Chinese bike 🤣

  • Am I the only one hear who doesn't mountain bike.... but watches everyday video. This man is an enabler to me when I do DIY projects. Love ya Seth 🤙🏽

    • Nope, I just ride BMX and watch this channel to lol about a single part that costs as much as my entire custom build bike. 😅

    • @demon rc 😂😂😂😂😂😂 thats awesome!

    • I haven't owned a bike for years. I started watching when he broke his leg cuz I thought it was an RC channel 😆 and now I'm definitely getting a decent bike someday just hard to make a decision on what one.

    • Yo, go get a bike. Then we can officially declare you awesome.

    • @Thom Perkins shhhh don't tell him that he needs to get a bike

  • Gotta go best of both worlds. Stash the battery up under the seat like before, and run the adaptor with the post turned 180.

  • Fun video but this illustrates the silliness of some wireless bike components. In the quest to eliminate one tiny dropper post cable we now have battery packs, worse form factors, and the always perfectly reliable Bluetooth connections to deal with. Sometimes it's just better to keep things simple.

  • Great video Seth! I hope Sram sees this video and upgrade their wireless seatpost :D

  • So soldier the wires directly onto the base unit removing the battery cover completely. Pro: you can grind back the base near flat with the wires.. Con: you have now irreparably damaged the base. Or... Get your favorite manual top action dropper, and wire a wireless solenoid to it yourself... and It will probably cost WAY less.

  • This is exactly my thing: how can I "improve" this ridiculously expensive item without destroying it? Sometimes I cancel the project, sometimes tears will be shed.

  • I see the merging of the RC hobby and mountain biking has come through again! Except I'm not sure I would want a lipo near that part of my body 😅

  • That's the kind of thing that would have me run a MX wheel size.
