Hello everyone! I apologize for the language; I'm using a translator.
I've been trying to finish reading this thread for six months, but due to the excessive amount of empty talk and philosophical reasoning, it turned out to be harder than I thought.
It's really strange that there's essentially zero useful information in 120 pages, and it's simply impossible for someone looking for answers, or even a beginner, to find anything.
I bought a blue erx v2 a year ago and only stumbled upon this forum after I washed my bike.
I don't know what's going on with your v3, but the v2 is just as much crap as the v1. Judging by the fact that they simply sealed the charging port (through which water was getting into the derailleur) rather than fixing it, I can conclude that the v3 is also crap.
A couple of pages ago, someone asked about compatibility with the Karo. It's there and works. In my training sessions, it even records the number of shifts, where and what gear I was riding, etc.
The chain tension really irritated me, even with the chain guide hole at its maximum position. A couple of times, my chain came off on bumps. I disassembled it and moved the spring bend to a different position, and got significantly more tension.
Even if you have a problem with the FD shifter, and it drains the battery, but not without it, 90% of the time the FD is to blame. If you're still experiencing battery drain, the FD is to blame, and it's just water in it. Then, share your experience, which I've been able to accumulate over the past year.
My friends have wheeltops, and they work great for everyone (there's a reason so many complete bikes are sold on EDS). If they were to break, it would be a serious stain on the bike manufacturer. I decided to get LTwoo, hoping it would work just as well. How wrong I was.
The brakes are fantastic. From bleeding to operation, they were the only thing I had no problems with. I was much less pleased with the 105 in terms of bleeding and subsequent operation.
Everything else didn't work properly for a single day. The front derailleur only works when I hit a pothole or kick it, and the entire group cuts out on climbs. I don't understand why this keeps happening to me. 🤣
The wires weren't frayed, there was just a break where the pins were soldered when I cut the insulation. I realized why—it's high quality! Luckily, I had the opportunity, and I was able to fix it. (It wasn't a problem, I just thought I'd share.)
The suppliers in my city stopped selling LTwoo completely due to widespread problems. I'm very happy with this decision, but I'm left without a warranty. I wrote to the sellers on Aliex. They listened attentively at first, then passed it on to the "engineers," but then the "official" account claimed it was my fault and that the device wasn't waterproof. I attached screenshots from the user manual, and they simply ripped me off. After each seller passed the videos on to the engineers, they finally replied that they couldn't help me because I didn't buy the product from them. But then, what's the point of all these weeks of back-and-forth? They knew right away that I didn't buy from them. I just wanted to connect to the factory through them, but they ripped me off and aren't responding.
Next, I'll share my experience with disassembling and repairing the RD.
If anyone can measure the Ultegra OSPW mount for me, please let me know. I'd be very grateful. I only have the 105, and it has slight differences in the mount. I want to replace the OSPW, but I don't want to buy the ltwoo. I'd like at least the Ryet, but I want to be sure of compatibility.
