LTWOO ER9 & ERX - Electronic groepsets

[raisinberry777]

is there really anybody participating in tt events and risking it with ltwoo components?

It's a hard sell when a SRAM 1x TT setup is pretty cheap.

especially as, from what I've seen so far, ltwoo only comes with one set of controls, the inserts for the end of the extension bars. So no shifting while out of the extensions and only compatible with traditional round, "pole" extensions.

Just trading in everything from performance to usability for some cost reduction

5) I also can't untrim which is annoying. I often end up in a situation when the chain rubs, I click trim and it starts rubbing even harder but now that I can't undo it I have to shift in the rear, click trim and then shift back to the gear I was in before.

I've been riding it for 2 days only at this point so maybe I will eventually figure it out but at the moment the way the FD works is a mistery for me.

i had the same problem but after an update fix that. now doesnt need to go in small gear and back to big . if i press the same bottom again makes trimming depending on what gear it is at

[jonathanf2]

can anyone explain how to set up the front derailleur, please?
I find it really confusing and can get rid of the rubbing.
1) FD cage on ER9 i really narrow for some reason and when I set up "limits" the chain starts rubbing on the inner plate before i can move the outer plate to required 0.5mm.
2) I can't understand when the derailleur moves to those limit positions? when i change the gear or when I changed the gear, i'm in the hardest gear and click trim?
3) What front derailleur "micro adjusting" means? Whatever I set up it feels like the derailleur ends up in some random positions anyway.
4) I can't undestand how the trim works. When I'm in a big ring I can click trim and it moves the derailleur but where? The micro adjust position that I set up?
5) I also can't untrim which is annoying. I often end up in a situation when the chain rubs, I click trim and it starts rubbing even harder but now that I can't undo it I have to shift in the rear, click trim and then shift back to the gear I was in before.

First adjust the FD on the lowest gear adjustment and next the highest gear adjustment. Once that's complete, adjust individual cogs starting from the highest gear in the small chainring. That should be good enough to insure the big chainring will shift well. Make sure your limit screws are properly adjusted as well. I have 2 ER9s and I have both FDs properly setup.

Saying that, I still think the LTwoo FD is the weakest link in terms of design and it just annoys me that there's no skid plate to keep the FD cage from brassing.

when I open front derailleur setup I have a "micro adjust" slider. what does it do? Is it supposed to set the derailleur position for each individual cog in the rear when I use trim? Because I don't think that is what's happening. When I navigate to limit setting and set the limit for the hardest gear and go back, the "micro adjust slider" is now set to whatever was selected for the limit. Now I shift into lower gears in the rear and move the slider until I get rid of rubbing on each cog. Once that's done I try it out and shift through the cassette and it's rubbing on pretty much every cog. When I use trim it moves the fd for some of the cogs in the rear but does nothing for others so it just keeps rubbing. Also that trim position is for sure not what I selected when trying to "micro adjust"

I always start with the high limit and low limit adjustments for the FD before adjusting individual cogs. Also make sure you're on the correct cassette speed (10/11/12) and make sure your RD hanger isn't bent. It's possible you have to physically adjust the FD hanger itself. It could be off a 1-2mm causing rubbing.

My experience so far. I bought the eGR 1X12 in October 24 for a ICAN gravel frame. All was good till recently, when it the battery started getting drained, and on a longish ride I was stuck in 5th gear. I recharged it and did a measurement that showed it was losing about 1%/hr of charge just sitting. I have contacted the seller from AliExpress to see if there is a solution. I suspect a moisture leak and a short. Anyone have a solution?

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...

[mozart]

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).

i send message to 80 designer. and that is the ansewer. "Yes, dear Kostas, you can place the order by below link and leave a message on your order, we'll send the 2025 latest version to you directly, thank you".
link is from old erx but they send new one

You received a new RD derailleur (blue) and it does not have a charging port, so now how do you charge the derailleurs?

looks like there's a v2 and a v3 of the blue versions. Trace Velo just dropped a video of the v3 and the v2 has the same charging port as the v1

Just watched the video - the first impressions of v3 seem very good. Hopefully ER9 isn't far behind - that's probably where the real value proposition is, since ERX is getting quite close to 105 in price.

Seems like look and operation is premium though - hopefully the reliability is closer to the mark than v1. Hopefully availability of spares is decent too.

Has there been a mention of eR9 for this generation? I've only seen eR9 for the first release. Still can't justify eRX prices over discounted 105 di2, but with a 50ish discount on eR9 that's a different question
