On android go to setting -> apps -> find ltwoo app -> there you should be able to clear data and cache without reinstalling

Thank you very much!
I could connect the app to the RD, but I cannot login to my Lwoo account and my devices are not stored.

i cleared app data and cache, skipped login when loaded the app and managed to connect to the derailleur

Does that mean you deleted the app and reinstalled it then?

Same problem here. The known devices are all gone. The app searches and finds the RDs, but I cannot open the device data.

A friend of mine has a V2 and RD failure. Ltwoo offered him a new RD and cables. He asked for a V3 RD and they replied that V2 and V3 are not compatible.
Can anyone confirm that?

Hi, the hood on the left shifter of my Gen1 eRX group is torn.
I need a replacement, left side only or a set. Has anyone got an idea where to source?

My first gen erX worked also flawless about 2000km and two months.
But month ago it started draining batteries 2% in a hour while standing still

Same thing happened to my ERX. Contact the seller, you will get a new RD. It takes a few weeks, but try it.

Is there any confirmed information about the rx9/erx 3rd Gen. RD?
We all know that the 1st Gen RDs died, but we do not know why.
Has LTwoo ever given the technical reasons for that or at least informed that they have solved the bugs in the new 3rd Gen?
Has LTwoo ever admitted that there was a bug in their RDs?

The cheapest spot to buy LTwoo groupsets is from the LTwoo official choice store. Just make note, The LTwoo official store won't warranty coverage the items. I did risk buying my Ltwoo eGR groupset from that choice store since it was under $300 USD, but I knew what I was getting into and the savings was worth it to me.

there may be some shops with near-identical names , but I had bougt from this Ltwoo official store
https://ltwoo.aliexpress.com/store/910450018?spm=a2g0o.order_list.order_list_main.8.1d8c5c5fe69jIu

And they did send me a new RD for my ERX  on warranty!

According to 80 designer store everything can be mixed and will work together. Good news for broken RD's! But they aren't selling them seperately.

I bought a ER9 RD at 80 designer store 4 weeks ago. 151 Euros.

Seems a lot of the sellers exclude the battery, only include the battery casing. Searched through LTWOO's site and manual but no mention of what battery types the battery case accepts. Anyone know?

Any type 14500 batteries. 3,7v and 800mAh. Available anywhere at about 5 EUR a piece.
Make sure that the +pole is not flat, there are two options for that. The raised pole is what you want.

I love that groupset. When it works... +1 on that, couldn't agree more.
How does the blue differ from the old one? Could you please share a photo?
Is that store selling the ER9 / ERX both old and new versions on different listings? Are there listings for the ERX / ER9 with the new brakes? (the lighter ones with less bulk around adaptors).

There is a difference in appearance, the new version looks much better. As far as the interior is concerned: I have no idea if they removed the bugs or not. The charging port is where it was in the first version.

i had a phantom drain issue as well... 80 Designer Store and LTwoo warrantied my rear derailleur and sent me a new one.

I had exactly the same problem with my ERX. L-TWOO Official Store honored the warranty and sent a new RD with cables. It took 6 weeks (chinese new year and so on..) but now I am happy. The RD is the new model ("blue"), installing was easy and it works fine.

I love that groupset. When it works...
