LTWOO ER9 & ERX - Electronic groepsets

[boxof13]

Does anyone know if we can pair eGR with the front derailleur from eR9/eRX? I'd like to have 2x chainring at the front with eGR rear derailleur. The eGR shifter almost looks exactly the same as the new eRX shifter, with larger buttons.

[aramus1979]

Do your front derailleur guides wear off the chain so quickly? I've traveled maybe 500 km and the derailleur slide looks bad. What will it be like when I've traveled 5,000 km? It's probably a hole right through. I'm very concerned about this

I had a deal worked out with ltwoo regarding
Bring in to USA the electronic group set but they did not
Respond to providing me with a couple units for warranty exchange
For my USA based customers. The group set is great
And have it installed on 2 of my personal bikes
No problem with the set up and all went well..it now
Going on 1 and 1/2 years of full experience..
I'm glad you have yours working if I can help any one else
Be happy to.

What's the general feeling towards ltwoo erx in spring 2024? I've been tempted to pull the trigger on a number of occasions but too many of the YT influencers saying it's not a finished product, has inherent problems etc ( maybe ltwoo aren't paying them enough to endorse). Aliexpress have a sale this week, never been a better time to buy however I value reliability over anything.

I've been thinking about this myself. With the "blue edition" around the corner, I have a feeling LTwoo is trying to off-load the remaining product before release of the updated model. Maybe if I was building up a new frame right now and wanted to save some money on the groupset, I might pull the trigger. If I was upgrading a current frame to electronic, I might wait for the new version to be released.

If you value reliability over ANYTHING, then buy Shimano.
YouTubers often receive early units and they serve as beta testers. Bad strategy? These YouTubers had the battery with tabs and not springs, which caused most of the concerns.
Your concern over shilling is also warranted. Anybody who has a discount code on anything has an interest in you spending more, mathematically. And so if you don't see a discount code on l-twoo, they don't stand to benefit, which is worse. If they don't make money from it but then users report problems, then they just shit themselves in the foot twice.
I'm very happy with my 5 er9, but I kind of want them to fail to see what happens. I enjoy the tinkering and the grind of making my own bike infinitely more than buying off the shelf pre packaged branded stuff. Shimano for me is a patent troll and SRAM is the worst assemble of engineers in recent bike history, so I will get out of my way to try alternatives.
I still use a Shimano group on an old bike. That stuff will never die. You probably should buy Shimano if your key concern is reliability. L-twoo electric groups didn't exist a year ago. Nobody can tell you how they age long term. They may age like fine wine, they may age like Lindsay Lohan. Do you want modern day Lindsay Lohan on your bike?

I have to agree with many of these. I am now already >5000km on my first eR9. I have to admit, almost half of which are indoor Zwift rides (don't blame me, I am a fair-weather rider and don't like to be miserable on the bike during winter). I got another set for my wife's bike. These days, with discount codes, you can almost buy two eR9s for a price of Shimano 105 Di2. That is just a no brainer for me when I want to maintain more than two bikes. It's also convenient to have "spare" parts on one bike if/when anything goes wrong on the other. Some stores on AE are now listing individual parts already.
I am actually thinking of getting another set for my commuter bike. Still trying to figure out if I should get eGR or eR9. I want to run 2x on eGR, but not sure if that works. I'd imagine if the firmware allows, it should be straightforward since everything else is identical. I do have an extra front derailleur to use, so that would be great.
I am hoping my eR9s would age like Lindsay Lohan on fine wine diet.

Am I blind or there really is no rim brake version of ER?

No rim brake version. Seems like Wheeltop is basically the only Chinese option for electronic and rim brake.

AliX (80 designer store) is the answer. Right now at 532$ and at the checkout incl. VAT-discount, 18$ cupon and exchange rate to € i end up at that 400€ mark.

Today they have sales. at checkout the price was 372€.

This seems a bit concerning. Is anyone else seeing something similar?

I've got about 2000km on my ER9, only some scrapes on the FD guide.
Maybe the limit position is incorrectly set on OP's setup? Or he isn't hitting the trim button every couple of shifts?

[zerstorer]

Looks like the chainline or the limits are not properly set. There shouldn't be rubbing during normal riding.

[aramus1979]

end positions set correctly, there is no friction during normal driving, what you see in the photo was only caused by changing from a small top to a large top

Also when you buy the "no battery" option, does this mean you still get the battery holder and have to buy the batteries yourself, or do you have to buy a battery case?

You buy the batteries yourself, everything else comes with the kit (battery holder, charger, wires). Also, my shifters came with the coin cell batteries installed, no need to purchase these.

Given the choice with the current sale, would you go with ER9 or ERX? With the ER9 I could offset the weight adding a lightweight 12 speed cassette and 2x chainring. I've been thinking of going 12 speed 52-36/11-34t. If I opt for the ERX, I'd stay 50-34/11-32t. Either option would be priced the same with the discount codes.
