WheelTop EDX OS Series Wireless MTB Drivetrain

Check to see what order the lock retainer and retainer with the bent tang are on.  I had 2 of my EDS OX derailleurs assembled with the "B" screw tang assembled below the retaining ring and they both bound up when I would tighten them.  Swapped them to what is shown in the attached image and they swivel on the hanger when tight.

thanks, but unfortunately my EDS OX 2.0 is completely different and it doesn't have the same assembly.

My next problem child.   The Gen1 EDS OX removable battery rear derailleur that I mounted on the FS MTB bike I build last year has always has shifting problems from the get-go.  I had only ridden this bike around 125 miles until last week. (I just rode it another 100+ miles last week.)    During the 7 days of harsh single track riding, the derailleur was continuously having shift problems.   (Of course, all my riding buddies speculated on that the problem is/was.)

When I arrived home, I noticed that the derailleur body wobbles around the hanger bolt.  (Hanger BOLT is tight!, and hanger is not bent!)  It wobbles enough that it sometimes wont shift into the 12gear, or shifts up or down by itself depending on pedal load during shifting.

I removed the hanger bolt, to discover that this derailleur is machined differently than my other 4 gen 1 EDS OXs.  Looks like Wheeltop improperly machined a bore too deep into the derailleur body, and rather than scrapping the part, they did some "rework" with a custom aluminum C-ring (second pic.) and a washer.   This fix they did appears to me to be a Cloodge so they could throw the derailleur over the fence and sell it through an "unauthorized seller"  (I wonder how many of these problem children have been made and sold.   (I have another Gen1 EDS OX that had manufacturing problems that they wouldn't warranty, where I had to hand file an interference to get it to shift smoothly.)

I am attaching some pics of the problem.  I have no choice but to resolve this problem on my own, because I doubt that Wheeltop will step up and give me a replacement derailleur due to their terrible quality control!!! 

Note:  in the first image the "defective body" is the lower derailleur in the picture.  If you look closely, you can see that the bore into the body is deeper by close to 2 mm, versus the derailleur shown in the top of the picture.

Did SRAM's battery patent expire? It looks like Wheeltop is going back to replaceable batteries on the Wheeltop EDS OX

I wouldn't make that assumption unless it is posted on an official Wheeltop store or their website.
Is Twitter Bike World even an official Twitter retailer?
Seems to me like an Aliexpress store trying to sell of old stock.  (Photo they are using is the same stock photo used since EDS OX originally was released.)

But this is not the latest 2.0 version? How did you get this price?

I'm having an issue installing OX 2 rear derailleur.  Specifically the chain doesn't appear to run over the rear pully correctly and rubs against the top of the cage when pedaling.  I assume I am doing something wrong - can anyone offer some advice?  For reference the chain is a Chinese made 12 speed that was working fine previously with a GX Transmission rear derailleur.

Narrow-wide pulley? Make sure to fit the pulley correctly to the inner and outer links of your chain.
Had the same issues while installing my GeX derailleur before realizing that I was stupid

Snapped a 6 month old chain during a laggy EDS downshift yesterday morning.

Tired of it.  I have played with the system for 6 months trying to get it to shift consistently. New hanger, new cage, laser alignment, messing with the micro adjust program, fiddling with b-limit screw etc etc. The system hasn’t wanted to shift clean for months.  It worked fine for about a year then all of a sudden about 3 miles into a ride this past January it decided it didn't like to shift down the cassette one gear/click at a time and would randomly go way out of adjustment mid cassette and be fine moments later after shifting all the way down and back up.

Slapped on my old SRAM GX derailleur and mech.  Half hour to route the new cable, 10 minutes to set it up.  Damn this old cheap sram system runs so quiet and shifts good.

Anyways, EDS is out. Thrown in the misfit toys bin.

I had very similar experience with my very first EDS OX installation.  I eventually discovered that my problems were associated with the initial positioning of the derailleur on the hanger combined with the "B" screw setting.  On the frame that I installed the derailleur on, the initial centering of the upper pulley to the 10 tooth cog, put the operation of the servo and parallel plates in what I call a dead zone area.  I installed a spacer washer, (1.5 mm) between the hanger and the derailleur mount and then re-calibrated the initial position to the 10 tooth cog.  By using the washer, in effect I forced the cage to be calibrated farther up into the travel range of the derailleur.  Immediately, shifting improved 1000% once I trimmed the shifting for all of the 12 cogs I had fantastic operation of the derailleur.   I also found it important to get the upper pulley properly aligned using the "B" screw along with the correct chain length. 

Since this experience, on the next 2 bikes I installed the EDS OX derailleur on,  I made sure that the initial calibration setting (1gear) was out of the bottom "little to no motion" zone of the derailleur.

Thank you for that information, I'll give that a shot over the winter to see if it works for mine. My thumb misses the easy click button more than anything.
