I bought a second hand SRAM AXS derailleur from eBay some months back, very quickly I noticed there was intermittent power issues. Eventually it stopped connecting and it appeared to be the little pins (pogo pins) not moving free enough.

I stripped it down and ordered 100 pins from Amazon, a friend who has the skills soldered the new pins (very tricky due to size) and it’s now working like new.

If anyone needs to do this fix please contact me and will happily post some pogo pins for the cost of a stamp.

Mine failed in the same way, I did the same fix, but my soldering skills were not quite up to scratch, and the first attempt failed after a few rides. I've resoldered them and hopefully this fix will last.


Can you link to the pogo pins you bought?

Hopefully this link works:

Mxfans 100x Gold-plated 6mm Copper Probes Spring Pogo Pin Connector https://amzn.eu/d/1ZtRbwI

If you need some spares just IM me, I have 98 left!

I am wondering if a bit of grease would help them, I suspect they got damp and the spring has corroded inside.
Hi, I have the same issue on GX AXS. My derailleur is still under warranty. Though it looks more than used. Many scratches and so on. So question is if warranty would be accepted or not. Anyway it will take some weeks to get it back. So I wonder whether to repair by myself or send it back. Repair seems to be easy to me. Am used doing this kind of things. However, the pogo pins are now out of stock. Would you, be willing to send some to Czech? Would of course cover the costs.

Pogo pins? I've never heard that word before.
I've always used "spring-loaded pins."
Maybe it's a regional thing.
I can't wait to impress my friends and colleagues with my new expanded vocabulary.

Hello there,

Same issue on a Force AXS happened today. And a race upcoming in two weeks...

How can I have a couple of pins, please? Willing to pay postage and a round of beers of course.

Thanks!

Hey @Woodyboy, thanks for this - could I have a few to give this a go? Bike has been sat in the shed for ages as I'm at a loss with what to do with it - praying that this works!! Let me know how I can send over postage 👍🏻

I have had this happen on a GX AXS and a newer T type GX AXS. Mine were both replaced under warranty but
SRAM diagnosed the problem instantly so I think it is a known design fault. Seems like a lot of people with the same issue.

I took mine to e-bike motor repair and they put in replacement pins.

Damn, is it by design going to fail as there is really a huge amount of people sharing this issue with pogo pin, especially the right one.

I get that replacing on our own the pin could be an option or filing a claim - so out of riding for weeks (?) - but this does not related to a 1k+ drivetrain solution, barely acceptable. Reminds me of Fitbit watch where it was exactly the same on the charger, past a point, you new a new one as the pins just go out of commission.

They said dielectric grease should not be used but is it really? could it prevent the issue?

At the very least on some ebike we could powered the derailleur from internal battery but would be then also a bit of a pain to switch back to `no battery` for park days.

Great thread. In terms of maintenance has anyone figured it out? For example, removing the battery when washing the bike so that the pins stick out and seal up, or taping around the battery so that it protects from water, or using a syringe with dielectric grease to fill the inside of the pin?

In a pinch, some folks cannibalize the pins off their AXS charger:

I don't think it's caused by water, mud etc, I just think it's down to crappy component choice by sram.

I've just had my t type derailleur fail in exactly the same way as my old gx axs derailleur, one of the pogo pins fails and stops contacting the battery. It's really unacceptable that this happens and means I could not recommend axs to anyone after my experiences. If you Google people are getting this fault with all srams wireless components, road bike stuff, seat posts etc.anything from sram using the pogo pins can fail like this.

Anyway, I have currently fixed mine by soldering a small blob of solder on top of each pin, it's now working, but who knows for how long.

It is really something I encounter across tons of different pin device, just a matter of time. That said yeah maybe the blob is good is you can make it small and clean enough.

Interestingly the pins (part number P70-2100045R) are not something I have seen failure reports when on the Reverb dropper seatpost. And they fail on the derailleur more often than on the charger. It could even be because of the vibration cracking the components. I will appreciate it if you do not make a straw man argument. Thanks.

In my experience, I was able to completely eliminate fallacious arguments by cancelling all my interweb accounts and avoiding people who spend their leisure hours as Tik Tok Jockeys.

But on to your statement about the pogo pins. I think you might be on to something about the vibration at the derailleur vs the vibration at the seatpost. Or maybe the environment is a factor. The derailleur gets more water and dirt than does the seatpost. But I don't have enough data to reach any conclusions. I put over 3000 miles on my AXS, and over 1700 on my Tranny without any hiccups. The only guy I know who has had a problem had less than 1000 miles on his. But he's the guy who washes his bike and shows up at the trailhead like he's trying to win Best of Show at the Concours d'Elegance. Like I said, insufficient data. But just to be safe, every once in a while I get a little silicone grease on my finger and wipe the rubber seal on the battery. I've thought about giving the pins a little squirt of electrical contact cleaner/lubricant, but worried that it might actually create problems where none previously existed.

To my knowledge it is the environment non the pin themselves nor vibration. The wear occur to due to dirt/grease/water/moisture etc, like I said this is a common problem on similar product with pins where they are in contact with skin/moisture/dust etc.

Charger is totally clean and do not walk in mud, I hope as I do, people clean their battery and dry them if they are kind of wet before charging. So this is not relevant at all to compare it to the pin on the derailleur.

Honestly this is not something new or proper to mtb, depending on environment "hazard", the pin collect whatever micro debris/water/moisture and die, note that there is no way to fix them without breaking them - at least I have never found anyone succeeding when they do not expand as they should.

Suit yourself, just putting my experience and opinion out there, that pogo pins are not a suitable solution for the environment that the axs groupsets find themselves used in, and that sram are continuing to sell these knowing full well they have a high failure rate.

Sram could have changed the pogo pins to a more suitable solution as part of the t type release, but didn't.

It almost doesn't matter what causes them to fail, because I don't believe that we as riders can do anything to prevent failure except not using them.

We shouldn't have to baby them, or treat them any differently to cable operated derailluers, they should just work.... Without us having to put measures in place to protect the pins, sram should have done this from the start if the pins are vulnerable to dirt, water etc

There are reports of road bike (axs force) rear and front derailluers failing in the same way as the Mtb derailluers, and road bikes get a far easier life in terms of exposure to mud, dirt and vibrations than mtb.

They're (pogo pins) just not fit for purpose in this application , which is the point I was trying to get across in my original post.

Anyway I'll update on how long my blob of solder 'fix' lasts for, if anyone is interested, it survived my ride today through some horrendous weather/mud/rocks etc

I am not sure of that, on road you have lots of contamination too, I would not say they are clean and definitely moisture can develop in there too (eg: easier to contaminate your pads on road than on trail).

That say as always we are guinea pig from a dying industry.
