WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)

Need some help guys, trying to replace pads but the ones I got where too big, any links or recommendations for a good set of pads

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?

Update on my wheeltop experience: Initial setup was a bit tricky and I need to fizzle around to get it shifting smoothly, but in the end it worked well (on a shimano XT 11-46 cassette).

I was running it for ~350km mixed terrain on my hardtail, no really heavy or muddy conditions, no races. Some weeks ago after winter I cleaned my bike (no high pressure, just normal water in the garden). After some days I wanted to ride and the rear derailleur was just dead. Tried to charge for some hours but nothing changed.

Contacted wheeltop and after them sending some videos, they confirmed that the battery of the derailleur is dead and they will send me a new derailleur (after sending the old one back).

Main reason for me to choose wheeltop was, that I wanted to use my old 11spd stuff and don't need to invest in new freehub body, cassette and chain until it is end of life. But my overall experience is mixed as the setup was not really easy and on the first occasion it just died. Also the charging was annoying to me (I know, it is not their fault, SRAM patent).

In the meantime I got a used XX1 AXS groupset for a good price and will change to SRAM (I already run a SRAM XX1 AXS on a different bike and I like to be compatible to change spare parts when something breaks).

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!

Anyone? Would really appreciate any help.

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
