I was excited about this group when I first heard about it but with all the issues ERX has had, I'll definitely wait this one out a bit.

Same, either that or wait for Sensah. If their full mechanical group's quality is any indication, I think Sensah will be better than what LTwoo did in first attempt.
-
I’m also interested in waiting for tests in the 2x system, I wonder what the capacity is, I like their compatibility like SRAM and much better than Shimano.
-
Any news? Maybe directly from Ltwoo, if they read this as well...

I see it available at the Ltwoo official store on Ali. Not sure if its been updated from the version we've seen on the Trace Velo youtube channel. That version had some issues.

Do you have a link?

i've installed 5 er9 and 4 sensah 2x11 mech. for me, LTWOO > Sensah, any day of the week. The FD from Sensah is useless, i've had a Sensah RD die on me for no reason and Sensah told me to go F myself. Meanwhile, at least until now, my experience with ltwoo has been flawless. I'll be the 1st to start shitting on them if that changes, though.
People here keep saying erx has had problems. Afaik, the sleep issue was because of batteries with tabs instead of springs, that's fixed now, and SOME have complained about water ingress in the cable port of the RD, which you can seal with grease or liquid electric tape. Tracevelo literally submerged his egr and had no issues. I'm not aware of other issues?
And the er9/erx even has more functionality in the app than shimano; i dont get the hate.

Where do you buy your ltwoo parts? Find them very unresponsive on Ali.
They don't even answer basic questions :s

I bought 5 groups at once via an OEM supplier. I also have a wechat contact who works there but he's rather unhelpful, wouldn't recommend him.
As a friend says, never underestimate workers' ability for incompetence.
You can probably ask your basic questions here, almost for sure we collectively have put more miles on these groups than they have.

I bought my GR9 roup from 80 designer store. They helped me with a few things after purchase and installation. Usually respond within 24 hours given the time difference.

Just noticed that! Same here. Was avoiding the ER9 deal but now it's getting hard to pass on.

Could not resist the eGR offer during the current sales with a 40$ coupon...
Let's see how this works out...

I have both ER9 and EGR in the cart. I like how EGR looks compared to ER9. Was planning to install it on VB GF002 which currently has Ultegra 8050 on it but then I realized I use that bike as endurance bike with 35c wheels and very light gravel thrown in where the current 11-34 cassette coupled to 46/36 chainrings work fine. May be I should just get the ER9 and also save a couple of bucks in the process.

I think LTwoo shot themselves in the foot with a max 46t limit with the RD. I'd rather just get a mechanical 12 speed 1x GRX 822 RD which gives a 51t cog capacity and is backwards compatible with 11 speed and probably 10 speed.

I think the chain was too short or RD B-screw set in too deep in Luke's video where he has problem shifting 50t cassette. It will *probably* shift 50t cassette with some smart play with B screw and chain length. Though I am hardly ever going to use 50t cassette as the jumps between last 2-3 cogs are just too much for any smooth shifting.
What I don't understand is why EGR is more expensive than ER9 considering it does not seem to have any better weatherproofing nor does it have FD.

Many thanks for the link! But there is only a version "without box battery" available. So this is worthless.
Alternatively, where can I buy such a battery in Europe and will the connectors be compatible?

You'll need to buy only 2x 14500 button-top lithium batteries ( https://eu.nkon.nl/rechargeable/li-ion/14500-16340/xtar-14500-800mah-protected-1a.html for example ) and probably 2x CR2032 for shifters. The battery module itself is included in kit.
-
Ahhh, nice! Didn't know that! I thought there would be a one piece battery pack included.

Any ideas about the possibility to use Shimano BR-RX400/BR-RX600 in combination with this groupset? Why I'm asking this: Could save work and leave the breaking cables within the frame and don't have to bother with this.

Should work without any issues
-
I think I did a thinking mistake. The braking hose on the shifter side most probably won't be compatible btw GRX und eGR. So yes, not really a saving of effort then since I will have to use the cable delivered with eGR shifters and pull them trough the frame.

Lots of people using er9/erx on a different thread here, it's maybe the busiest thread in the last several weeks. 2 out of my 5 er9 died a few days ago for no reason, and dealing with getting replacements is a slow burn nightmare, so right now, i wouldn't recommend ltwoo electronic. i like the hydraulic brakes and havent tried their mechanical stuff.
I dont think there's been clear communication around what's new / different since the launch of the erx. even the water ingress point wasn't addressed. basically it is evident that we're beta testing the stuff, but it's labeled a retail product. So nobody knows what changes they re making in the background on a running basis, or it they batch the changes into new versions.

Saw it there, remember you being very positive about the er9 when I ordered mine. The fact that they die without a reason is terrible. What reseller did you use?
Find the official store on ali bad in communicating. 80 designer store was a bit more expensive but atleast some kind of service there

Nowhere near as many reviews of this group as ERx. Trace velo had some issues with his. Don't know if he's done a more recent update on it.

~$350 now :D but gonna pass. The recent surge of issues is enough to deter me.

Yeah i went from loving it to WTF is this?
I bought the groups via Winow, and i dont think Terry is a good professional. He seems like a nice guy, but he's at times elusive, slow, evasive, vague, it's extremely irritating. He clearly cares about himself, but he doesn't seem to care about our problems.
I since had a look at groupset prices in Europe and they're still insanely expensive, it infuriates me. I understand that SRAM prices are very attractive in the US, but that's not the case in Europe.
I kind of want half of the cycling industry to go bankrupt to clean everything up. A 10k bike was never worth 10k, let alone 15k. Groupsets shouldn't start at 1000 eur.
-

SRAM prices aren't very attractive here in the USA as well, not to me at least. Nor Shimano's. On the contrary I was under the impression Shimano stuff is much cheaper in Europe. Cheaper, relatively. Nothing is as cheap as LTwoo or Sensah though.
-
The reason i went for ltwoo was because of a crash where i had to replace an ultegra 8070 shifter. Hard to find them and prices at 300€ retail for just a shifter..
These prices are ridiculous.

Hello, I just joined this forum to jump in on the discussion of the eGR. I ordered one and just installed it last night. Well, almost. Ran into an issue bleeding the brakes because I didn't have an appropriate nipple to plug my syringe into the caliper port. So, waiting on a new bleed kit to come in tomorrow with a selection of various sized nipples. Also, need to finalize how I'm routing the power cable, as of now it's just taped on the chain stay.
Either way, I'm disappointed to hear about the sudden influx of issues. I hope I got a newer one.
My hopes are high as my initial impression is quite good. Shifting is smooth and fast once I got it dialed in. I'm coming from a Microshift Advent X 1x10 setup where I was using a Microshift Sword 11-38 cassette on a "road" type wheelset and the stock boat anchor cassette on a gravel-esque wheelset.

I haven't heard anything bad about the EGR since it's newer. Your EGR RD should have a serial number on the cage. The first 6 numbers should be an indication of the batch. The problematic ER9 units seem to be from batch 250123. Perhaps EGR batch numbers correspond with the ER9/X or are completely different. Either way it'd be a good way to keep track for reference.
My ER9 unit is still working fine from batch 250123, so it's a bit hit-or-miss on why some RD units stop working.

I've attached a picture to the post to clearly identify the screw I'm wondering about.
I quickly set my eGR up this weekend and did a good 35mi+ group ride on mostly roads, and all was good. I didn't pay super close attention to how this linkage was set, initially, because it all seemed to work.
After the ride, I was doing some cleanup maintenance to get my crank and chain line better sorted. When I put the chain back on, my chain seemed loose, like the derailleur didn't have enough take-up or the chain was too long. With that, the derailleur was all the way up and contacting my cassette, with the grinding noise just like in Trace Velo's video where his B-screw adjustment failed. That was the first place my mind went, but after pulling it all apart nothing was broken.
What I realized was that when I initially set everything up, that linkage was much further back than it would naturally rest. When that screw (circled in red) is tightened to the torque specified on the screw, the linage doesn't move and the B-screw adjustment doesn't really matter at all. It's like in Trace Velo's video where he uses a lock washer to prevent movement, except I have no lock washer. Simply tightening the screw locks the entire assembly in place. Somehow it had come loose while I was doing that bit of work and that's when I noticed an issue. For now, I simply rotated the linkage back like I had it originally and tightened everything back up to prevent the derailleur from contacting my cassette. Presumably, everything will continue to be fine as long as the screw doesn't work loose again.
My question is: Is that how this is supposed to work? When that screw is tightened, should that link rotate freely so that the B-screw adjustment can move the derailleur, or should it be locked in place like it appears to do on mine? I'm really a novice with it comes to derailleurs, so I'm not really sure what is more typical.
-
Can someone help with the message above?
And did you also rode the groupset during wet conditions?
Hold up?
Klein Concet put the eRX into his shower (https://youtu.be/1Cmb-VGhjQI?si=xXkYhC2Na_N1pHDY) and it held up. Would wonder if the same holds for egr?
-
I've been riding this week with it, not as many miles as I had hoped but a little over 60mi so far. I haven't taken it off-road, but I took a few trips to a parking garage and rode about 30+ times up and down. LOTS of rapid shifting and so far it's held up great. I'll be taking it on a century ride in a couple of weeks, so hopefully I don't end up stranded in the middle of it. I haven't put it through any water yet, but I'll get a bit more rough and rowdy with it off the road once I am done with my century ride.

I don't have any experience with eGR specifically but in general rear derailleurs should be able to pivot around that 'L-TWOO Drive Systems' screw, yes. In practical terms, this is useful when you want to remove your (rear) wheel but the cassette starts jamming against the derailleur; with a free pivot, you can push the derailleur back, allowing for a clear path for the wheel to drop down. This may not be an issue with your particular frame, however - I guess it's easy to test.

Thanks for your thoughts, that makes me feel a little better. I'm about to do a little maintenance at the end of the week in prep for a long ride I'm taking next weekend. I'll take one last look at it before I leave it alone for the time being.

I’ve had mine for about a month and a half. Not a ton of miles, but I should start logging a lot of miles soon. Zero issues so far. Initially the groupset only worked when plugged in. I knew what it was right away, the 1st set of batteries I ordered were a hair too short and were not making a proper connection. Ordered a different set that had a taller “nub”. That is not the groupsets fault, it’s a common issue when using these types of rechargeable batteries.
I might order another set, but would like it in carbon. Although the price will be higher than the $350-$375 you can get the current groupset for.
Here are the ones that worked well, surprisingly they were the cheapest ones too

Pretty much my experience so far, as well. I'm coming up on about 2 weeks of it being up and running, at about 150mi. By the end of next week I'll have about 300-350 mi on it, but mostly pavement so nothing too rough. It's been excellent so far. I initially was worried about battery drain, because my first couple of rides the battery drained super quick. I think it may have been some kind of break-in or first-cycle issue with my cells rather than a derailleur issue. Rather than top-off on my first few rides I just let it continue running down until it registered just under 20% life and then I topped it off to 100%, that probably got me about 100mi or so (which was pretty poor, imo).
My last few rides, since then, it has seemed to drain remarkably slowly. After yesterday's 25mi ride, it didn't even budge enough to register a drop at all.

Funny Same thing here. Initially when I saw the battery just drop rapidly I was thinking it would last 80-100 miles at that rate. Since the 1st charge it’s been holding up very well.
-
I've been opening the app before and after each ride lately and taking screenshots as that's the easiest, most straightforward way for me to document shifts and battery usage. My last 2 rides totaled 65 miles and 1,167 shifts and the battery dropped from 100% to 91%. That ain't bad at all.

Thanks a lot for reporting your experiences!

I'm wondering if you got the bleed kit sorted out and have any thoughts to share. I've got eGR set on the way. I'm used to doing deeper install research before installing but there is so little on it. So any tips or cautions are appreciated. (or pointers to a more appropriate thread)

Very easy to install imo. The usual pain to run bike lines if you’re internal, but then just a regular bleed procedure as if they’re shimano levers. Plug it in and begin to fine tune the shifting in the app. EZ. I didn’t have to do anything weird in my install to make anything work. Besides the 1st batteries not working.

Actually... I did have some minor issues. Mostly because I ordered the "no box / no battery" package, so I did not get Ltwoo's bleed kit. I ordered some supposedly Shimano compatible kit from Amazon, but it came with only one type of fitting and tube connector. Unfortunately, there was no way to get my syringe onto the Ltwoo caliper port. I had to order a different kit from Amazon that came with a variety of different fittings and doo-dads and, fortunately, one of them fit the port. If I could go back in time, I'd much rather have ordered the Ltwoo kit because it was cheap and would have been a little less headache. But, it was a relatively minor inconvenience. Plus, the delay let me re-evaluate how I had run everything, and I was able to take a little time to shorten one of my hoses a little for *perfect* fit and finish.
Also, while installing, I was completely convinced that they had left out a screw that I needed for my size caliper installation. I checked very thoroughly and was absolutely sure it was missing. I came up with a work-around solution and was about to write them an email so they could send me a replacement or at least give me the specifications so I could source locally, and the only reason I didn't send the email was because I resolved to do it once I finished for the night. Anyway... I found the missing screw PERFECTLY nestled and hidden inside some spacer or something. I mean, it was flawlessly hidden. So, I guess they did a great job packaging the hardware. If you order the "no box / no battery" package it surely looks like a mess of stuff just randomly shoved in a box with a bunch of packing foam, but they did have some order in the madness.
Good updates on eGR. Any water tests or washes as of yet for you guys running eGR?
I kinda *need* mine to work this upcoming weekend as I'm riding it in a big century ride event I'm going to. So, I've been baby-ing it and being very easy with it. I'm surely going to be a lot more adventurous and abusive after that.

@amacal1: What kind of bleed kid did you buy? At the moment they only offer the version without box and without batteries on Aliexpress: https://de.aliexpress.com/item/1005006636427506.html

I am from China, and it's possible that I have access to information faster than others.
What I want to say is that although I haven't personally used the EGR kits, based on feedback from friends around me who have used it, the early versions of the EGR did not perform well in terms of waterproofing. All three of my friends experienced failures in the waterproofing performance of their EGR kits.
They obtained these early version kits either at the end of last year or the beginning of this year. I'm not sure if the recent updates to the EGR have completely resolved these issues.
-
Hi @FabioZang,
many thanks for your feedback! Question is, when did they have updated the version in order to be more waterproof - if they did at all?
If they did, how to ensure to get delivered the updated version and not the previous one. I have reached out to Ltwoo via Emai, but didn't get a response. Via Aliexpress I didn't find a "chat/message button" to get in contact with the "official Ltwoo store" in order to ask them those questions.
You might have more luck when writing to them via email in your language? Could you give it a try?
Are there similar forum chats in China about this topic?
Many thanks, Dennis

I think you can buy the Ltwoo bleed kit as a separate item on AliExpress.
On Amazon, I originally bought a "Borgen" brand kit, which there was nothing wrong with it other than the fact that it only had one kind of fitting and that fitting did not work with the Ltwoo caliper.
I then bought a "CYCOBYCO" brand kit that had a variety of fittings, one of which fit the Ltwoo caliper. This is not a full endorsement of that kit, per se. There seem to be many others that also come with a wide variety of fittings.
-
My eGR kit just showed up and I'm getting ready to configure. I ran into a question:
Is there a way to configure the shifters so that one can use BOTH sides at the same time?
I found that the app lets me change whether to use the right OR the left shifters to control the RD but see no setting to use both. On a side note, I find it hilarious that the app insists that the other one will be controlling the front derailleur which doesn't exist today on the eGR AND can't be powered with the eGR battery pack (the second power port is blank)
-
I was wonderung why both break leavers have shifter buttons anyway? Would only make sense if both buttons/leavers can be used for shifting the rear derailleur, true.
Are there 2 leavers for shifting on both sides or just one leaver?

I will try to ask them. Usually, I can contact them directly through platforms like Taobao or WeChat, without the need for emails. However, based on the feedback I received from secondary distributors in the past, the new versions of the EGR did not improve the waterproofing performance. In special cases, it is necessary to disassemble the rear derailleur and manually apply some waterproof sealant. But such an operation may result in the loss of warranty eligibility.
Based on the experiences of my friends, they had to wait until the rear derailleur got water inside and caused issues before contacting Ltwoo for repairs or part replacements (mainly due to water ingress in the rear derailleur). This process can be frustrating, and this issue may not necessarily occur in every kit. I am inclined to believe it could be a quality control problem. Moreover, purchasing Ltwoo from outside China would incur higher post-purchase costs, both in terms of money and time.
However, there have been some software improvements for the EGR, such as enhanced logic for situations like stationary shifting and accidental button presses. As for hardware improvements, there is currently no information available.
China does have similar forums, but we are not exactly like BBS forums. We are more like Reddit, with channels categorized based on discussion topics, and the discussions tend to be more basic. For more specialized discussions, we usually rely on WeChat group chats, which are more closed-off but allow for deeper conversations.

My eGR kit just showed up and I'm getting ready to configure. I ran into a question:
Is there a way to configure the shifters so that one can use BOTH sides at the same time?
I found that the app lets me change whether to use the right OR the left shifters to control the RD but see no setting to use both. On a side note, I find it hilarious that the app insists that the other one will be controlling the front derailleur which doesn't exist today on the eGR AND can't be powered with the eGR battery pack (the second power port is blank)
Ltwoo's idea is to use the left-hand button to control the electronic dropper seatpost. This dropper seatpost is expected to be released in the second half of this year, along with the mountain electronic derailleur. As for the accompanying shifting logic issues, it is indeed a frustrating design choice, but it seems that there are no other options at the moment.

That's good info, and I'm sure many people would be interested in an electronic remote dropper post option. I think it would be neat if there were some compatibility between the eGR lineup and the eR9 lineup, so that an eR9 front derailleur could be paired with a eGR rear derailleur and still function.
Also, I don't know how open the protocols are, but it would be neat if those buttons could be used to control a bike computer (i.e. scroll through screens on a head unit). We have these 2 extra buttons just sitting there, sure would be nice if there were more things we could do with them.
... AND can't be powered with the eGR battery pack (the second power port is blank)
THIS is the single most confusing decision I've yet seen made for this system. I noticed the same thing when I installed my eGR, that the battery pack has a space for the second power port but that it was blanked off. WHY?!!! I can't imagine it saves them money, if anything it probably costs more in the long run to have to maintain two different part production, stock, etc. Maybe it was to prevent issues related to moisture or other things, but then why not a little rubber plug or something. Even if it wasn't an elegantly designed rubber plug, just some random bit of rubber shoved in the hole that was a PITA to remove later would be better than no port at all.
Assuming that their customers like their products and buy more of them, it sure would be nice to have an extra battery pack that could be used between the 2x systems and the 1x systems. I'm still wary of how long my eGR may last and wary of all the reports about failures in the eR9, but so far it's been great and the price was incredible. If that continues to be the case, I could see myself buying an eR9 for my road bike.

I was wonderung why both break leavers have shifter buttons anyway? Would only make sense if both buttons/leavers can be used for shifting the rear derailleur, true.
Are there 2 leavers for shifting on both sides or just one leaver?
Both sides are set up for full control. Two paddles each. On one level, it kinda makes sense IF they are planning on adding a 2x gravel setup. Then it would be an easy add. But they only offer it 1x for now AND the battery case only has one port so you'd have to swap that out anyway. The battery case is surely a FAR cheaper component than the shifter.
I actually wrote to L-TWOO yesterday to ask. They confirmed that there is not currently any way to use both sides at once. The agent didn't say it was coming either but also said that IF it did they'd let me know :-)
Frankly, if they are going to ship the hardware that way, they should allow configuration of the buttons in the app. One option of dual control. But you could also set it up AXS style (up on one side down on the other)

Interesting (and unfortunate) news on the water resistance. Do we have any idea where the ingress is? I was planning on using dielectric grease in the ports to help ensure that isn't the ingress. But I wouldn't want to have to rip apart a new one to coat it with that or conformal coating.

Two good observations.
On the mix and match, I think it was in a China Cycling video on the Shanghai show where there was a claim of cross compatibility on all the e components. So that would make sense. I do find the dropper post thought interesting (and sensible) but not sure why you'd want two paddles for that unless they are going to make one that can be switch activated in both directions (someone has one of those with a pre-charge air tank allowing a certain number of activations on the trail)
As to the battery case, I had the same thought. It can't really be the economical decision, particularly when compared to a shifter with controls. There must be some reason but I can't figure it out. The only partly sensible idea was from my son who suggested that the way that end cap is built, the molding has the two outer rings in it. But the inner 'post' with the contacts comes from an inside plate that is molded with the wires. If that's true, it might be more sensible to use one of those parts with a single post and a blank to ensure sealing in the other spot. Then again, I'd rather have a second port as a backup for a few pennies more.

The attachment contains the reply I received from Ltwoo's official support regarding the waterproof performance of the EGR. The main point stated in the response is that the waterproofing of the EGR has been improved compared to earlier versions (at least according to their official statement).
... Do we have any idea where the ingress is? ...
Unfortunately, I don't have the physical EGR item with me, and my friends are also unaware of the specific areas where potential gaps may exist. All repairs are handled by Ltwoo officially.
However, I have a suggestion that may not be fully matured. Perhaps applying some waterproof spray meant for outdoor clothing on the outer layer of the rear derailleur could be helpful?
