WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)

[Tijoe]

I figured out how to get the derailleurs working again.  (Some input from the Facebook WHEELTOP Official Group.)

For several attempts trying to perform an "initial Calibration"  The app would state that I had reached the "travel limit"  and the derailleur would not move.

I rebooted the Wheeltop App several times.  Eventually, I was able to use the initial calibration features for the front and rear derailleurs and gradually/incrementally move the rear derailleur down to the 1gear, and the front derailleur onto the large ring.   Then I had to fine tune the gears back to my settings.

This is the bigger question:  Why did both derailleurs lose their calibrations such that the rear derailleur thought that the 7gear was the 1 gear, and the front set its travel limit to the small ring on the front derailleur.  (Just because the front button batteries had low voltage? )   I wonder how much pain and suffering I would have experienced if I had been on long ride, or somewhere remote, where I was sitting on the side of a road, or trail, trying to figure this problem out.

Does Wheeltop make the assumption that SHI* like this wont happen to the end user?   As far as I know, they haven't published anything to recover from this type of problem.   2 more demerit points!

Frustrating experience with this groupset yesterday, was doing a 75k cycle and the shifting suddenly stopped working at around 35k, it was moving in tiny increments and front wouldn't shift at all, couldn't figure out what was wrong so I figured I'd shut it down via the app and then it would power back on/reset once moving/shaking, it didn't, so I was left in a single gear half way through a cycle. Had to get picked up.

Once home I researched and it seems I must have accidentally put it into trim mode (right lever, light press small button for 3 seconds, light press small button 5 times after) which also seems to reset all gear settings, to exit this mode hold the left lever button down for 5 seconds.....don't switch this groupset off on the road.

What a pain

Hi everyone,

just received my EDS TX and so far everything went pretty smooth. But there‘s one thing that I couldn‘t figure out: since Im using the bike also on a smart trainer I have to regularly remove thr rear wheel. With the former 105 derailleur I could just swing it back and upwards and had plenty of space. The EDS however is fixed rock solid. Is there any hidden button/lever which makes removal easier?

Edit: ok I just tried again. I can just swing the derailleur it s just quite a lot of resistance.

hi! long time lurker of the forums.

i bought the wheeltop eds TX some time last year. it had failed & been replaced twice. both occasions failed due to water ingress. opened the rear derailleur and did notice some small droplets of water which ended up on one of the pins.
on the second occasion, it failed some 20 minutes before my Individual Time Trial. it was raining really heavily that time. really a big bummer & i have been using mechanical ever since.

i'm looking to re-fit my bike with a new set and in the future, for a gravel bike with the GEX groupset.

would like to know if recent versions have been weather resistant? my country is pretty rainy and humid (Singapore) and i tend to still continue riding regardless of the weather conditions.
it's a big concern for me and i'm hoping to give this another try!

I noticed that after riding in rough roads the RD loses its settings. I often have to go on initial calibration and move of few taps the RD. Anyone experienced the same? and maybe solved it

You're not the only one...   Problems like and very similar to what you experienced are being reported on the Facebook Wheeltop forums.   This past Friday, (May 9th) I had both of my EDS TX derailleurs stop shifting.  Both levers were not responsive.  (This is the second time this has happened to me.)   I was able to use my app to shift the derailleurs, but both derailleurs lost their "initial calibration" positions.   I performed a rear derailleur "initial position" setting from the 6gear, down to the 1gear using the app, and was able to shift/limp home shifting with the app.   I spent a lot of time the next day trying everything I could think of to get the shifters to pair/work with the derailleurs.  I gave up.  The next day, I tried shifting, and the shifters worked!   I had to reset the "Initial calibration" positions again for both derailleurs.   For some unknown reason/s they just started working again...

Other owners are speculating the following, but they have not presented any real data to support their theories:   1.  The EDS TX derailleurs are susceptible to hard impacts, or vibrations that somehow causes the derailleur to lose power, causing it to go brain dead and stop shifting.    2.  Some speculation that after upgrading to the latest firmware, the rear derailleur stops working, and will reboot itself sometime in the unknown future, causing it to stop working, forget what it is paired to, and as a result you have to set up the derailleur from scratch.   3.  When this happens,  the derailleur moving to the 6gear position on the cassette appears to be common with these problems.

I have to admit that I need some help concerning the EDS TX system I am running.   I can't figure out anyway to recover from this problem.

Yesterday, 17 miles from home after climbing a long hill I turned around.  When I tried to shift the rear derailleur, nothing!  I tried the front derailleur. No shifting!   I stopped and pulled up the App.   I could shift the rear derailleur a few gears using the app, and the front wouldn't shift.   I coasted down the hill in a lower gear.  When I stopped,I checked all of the battery levels.  50% rear derailleur, 80% front derailleur, 2.99 volts front derailleur shifter, 2.92 volts rear derailleur shifter.  (I replaced the rear shifter RH lever battery with the spare I carry. )
 This allowed the rear derailleur to shift and I made it home.  (Both lever batteries died at the same time?)   

This morning, I replaced both lever batteries with brand new Duracell ones. (3.3 volts)   Front derailleur light turns green, and I hear the motor buzz, but it wont shift.  The rear derailleur thinks that 5gear is 1gear, and it wont shift any further down to a higher gear.      When the rear derailleur is in the 3gear on the app, it wont shift down to the 1 gear to try to perform an initial calibration because it says the front derailleur has to be in the big ring.  But the front wont shift.   I've spent over a 1/2 hour trying to get the derailleur to move to the actual 1 gear position.     DOES ANYONE KNOW HOW TO RESET THE REAR DERAILLEUR DOWN INTO THE 1GEAR POSITION?   ANY IDEAS WHY THE FRONT DERAILLEUR WONT SHIFT?   Thanks.

I can't find any recovery features in the current version of the app to be able to manually move the rear derailleur back down to the 1gear (Highest cog on the cassette.)  Am I missing some feature in the App I can't find?   

Have this issue as well. But it's the first day, contacted wheeltop and Aliexpress shop but now it's too late to respond. The battery seems not being capable of moving the motor of the derailleur or it's broke. But I'll try it tomorrow again. Loaded the batteries, have the latest software, replaced the batteries from the shifters. Need to see how and what. Will read on the Wheeltop facebook page now as well. I also would like to know what you wrote in capital letters.

So, okay, I'm not the only one that's already a good sign, or not... but I had 1 lever that was dead so I replaced the battery and then it started. the rear derailleur didn't want to work anymore. Let's see tomorrow how it goes.

Anyone? Would really appreciate any help.

I have always saved this: compatible with LO4A brake pads so I didn't bought them yet but have them on my AliEpxress wishlist: https://nl.aliexpress.com/item/1005006305272176.html?channel=twinner
I can't say with 100% confidence that they fit but I would try these ones.

Had my left shifter die yesterday on a ride with no cell service at point of failure.

After riding 1x for a bit, got to an area with weak service and was able to connect with the app, no comm with left lever. Removed battery (known good, 1 wk old Duracell) reinstalled, nothing. But by leaving app open but minimized I stayed connected even after losing service again, so at least I could shift w app if I really needed it. Thankful for a 48 up front and 11-34, pretty  usable as 1x.

After troubleshooting at home, I found that battery connection at lever is spotty-the positive side is just a pc board trace with no "spring" to it, so I did open up the side springs (neg connection) to hold battery tighter, hopefully that will help.

Thinking about a little foil under battery. Anyone else had this issue and ideas for fix?

Edit, died again today just after leaving home. Found the issue, likely partly user error. When you insert the 2032, don't put it in flat, it must go in sort of rear edge down to avoid the little edge tabs in the rear getting their "spring" tension lost by being pushed, as they serve to hold the battery down against vibration. They're very weak. I bent them back out with a pick, carefully reinstalled battery, and its tight now.

Issue solved, AliX seller, send to me another RD and I got it yesterday. Connected everything but couldn't connect the shifters. Deleted everything again, and connected first RD then FD, this was working on the app. Then I took both batteries from the shifters out. Pressed the button and added the battery first right. pressed it down and hold the button in. blue pairing light paired. connect to the RD with cable loader on it. Took that off then it's also in pairing mode and Bam connected. Now did the same with the left shifter and connect it to the RD instead of the FD because that's the main connector (the RD) and Bam connected. problem solved!

However, I was too nervous and couldn't wait until the seller and Wheeltop resolved the issue so I also bought another one at https://xzxcomponents.com/ So in the end I will have two. So if I have got this problem again I have a spare one, this wasn't my initial idea but oke what ever I'm not gone send it back. And Facebook Wheeltop user group was a blessing, what a positive feedback with all the people that have issues.

Maybe one of you can help me. I bought a wheeltop eds tx groupset 2nd hand. The guy who owned the groupset stripped the FD fine adjustment bolt. And drilled a new bolt in there. I am trying to set it up; but the front derailleur has been a pain in *ss. Is the part I highlighted supposed to stick out this far?
