I just got called a racist by LT-Ray because I criticized the fact that they keep changing their groupsets. A few months ago I started saving to build a gravel frame and I was interested in building a 2X using eRX eGR mix. Ray sent me a video of the then current wired EGR rear derailleur working perfectly with their wireless MTB Shifters and with eRX Shifters. I was impressed.

Fast forward to today (6 months) and I am ready to buy the parts for the bike as I have saved enough money. I can't do what I wanted because wired EGR isn't a thing anymore and their wireless rear derailleur isn't compatible with the existing semi-wireless parts.

So I criticized them. I said that it shows there is no long term support for the products because if I purchase a part only for it to be discontinued a few months down the line. How am I supposed to get spares? I keep bikes for many years not for months at a time. I want to know a groupset that I am purchasing will be supported long term.

He went off at me! I got told I am not showing respect and that I am having bad attitude. Man respect is earned. You don't just get it for free. A customer is allowed to criticize and voice their dissatisfaction. Nope apparently I'm just a racist.

I guess I won't be buying anything from Ltwoo in the future ever.

Can I have some help with my ERX V3.


I was off the bike for two months and the bike with eRX sat idle for a bit. Now that I am riding again I am having issues.
It keeps stopping working mid ride. As if the battery is flat. I can't wake the system up without plugging in the front derailleur to power.
I checked the charge. The app says it's 100%. The light stays solid green on the front mech when charging.
My shifters show green when I press the buttons so the charge in those is still good.

Whats going on?

Hey guys. Can't remember if I have asked this before.

But is it possible to mix and match the Ltwoo ekectronic groupset parts?

Ltwoo doesn't have a 2X gravel groupset. But I want 2X.

Can I use eGR rear derailleur with eR9 shifters and battery and stuff?

Try replacing the seal and piston. In general I don't have any issues with LTwoo calipers. I detailed the piston replacement procedure on the maintenance sub-forum. It could just be a bad seal. Also this problem isn't isolated to LTwoo, same issue happened with my GRX caliper prompting me to look at alternative fixes.

I can fix it. That's not the problem. My problem is I bought a product with a warranty. And if something is faulty I expect it to be fixed in accordance with said warranty. I don't expect the manufacturer to play the blame game and deny my support request.

If Chinese manufactures want to be taken seriously on a global level they can't keep falling into same stereotypical "good luck with Chinese support" pitfalls

Found it.

My brakes are leaking from the pistons.

Anyone having issues with their brakes getting air in them or something?

I have had to bleed my rear brake twice now in the four months I've had my eRX. Specifically the rear.

I pull the lever till it bottoms out and there is just no brakes. Any ideas why this would happen?

So, I took the new v3 eRX for a spin the other day. I certainly appreciate the improved ergonomic of the new shifters. The button click feels better somehow—it's like you need that extra push to make sure it actually shifts, which means no more second-guessing if you pressed it right. As for the shifting speed, I can’t really say it's any faster because my old eR9s were already pretty quick.

One thing I that find odd is the choice of not allowing power delivery using USB-C to USB-C cable. You can only charge the FD using USB-A to USB-C cable. I assume this is to avoid charging higher voltage!? I tried bunch of cables and pretty much confirmed this. Not a deal breaker, but it would be a bummer to look for the right cable to charge the set.

do you find your v3 levers rattle a bit over bumpy terrain? I'm finding mine a bit rattly and I am looking for hacks or solutions if anyone has.
