LTWOO ER9 & ERX - Electronic groepsets

Every time I read the new posts in this thread, I am so happy I became a Wheeltop EDS OX and TX user.

Hey, but now we have the first report of Wheeltop TX PCB corrosion! 

I think all these electronic groupsets have certain compromises, even Di2 and AXS. It really just depends on what's acceptable for the end user. Though I'm still interested in what Wheeltop is doing. Hopefully prices will start to drop in coming months, especially once Magene comes out with their electronic groupset.

Wheeltop seems interesting, I especially am interested by the cable-pull version for modding old bikes. But.... Those prices really need to drop. No way would I pay what they're asking for Chinese groupset. Only reason I'm using my Ltwoo set is because the price was worth giving it a go.

Maybe I'm a lucky one, but I've had *zero* issues with my eRX gruppo from Sept/Oct last year. I've got a couple thousand miles on it and no issues at all.

Knocking on wood, I really love it and have the gravel set on my list for a gravel build soon.

I'm building another bike with 105 di2 and will sell my ER9 bike. But so far no issues and racing with it every week. Also knocking on wood, posts here do frighten me.

Ltwoo has a website with fairly good listing of documentation. You can find the manual for the eR9/eRX series, and it's actually a pretty good manual. It clearly states that you can do fine tuning of individual gears through button presses on the groupset and brifters. Please go check that out to see the procedure. However, I don't see anything about being able to switch from 12speed to 11 or 10speed via buttons, so I think that functionality may be only available through the app.


How did you arrive at this answer? As far as I can see, the app is not mandatory (except to switch from 12 speed to some other speed cassette).


Exactly my thoughts. Except it doesn't even appear to be necessary to worry about long term app functionality, as you may only *really* need it to re-purpose the groupset onto other bikes and maximize your use of it long term. If you simply install it on a bike and keep it on that bike, you probably won't need the app 10 years from now as long as you keep it on the same bike.

Well, i have asked which functions can be set via buttons and i did not receive an answer, yet...but it has only be 8 month...i think i will have to patient...lol

As far as matching functionality to Di2, not even Shimano lets you swap the number of gears or even let you microadjust through an app so it's already a false comparison. If Ltwoo goes out of business tomorrow and their app ceases to exist, then you'd still have an electronic derailleur with as much functionality as a Shimano Di2 derailleur, right?

Roughly 3.500km and 24.000 shifts on my er9, here. Haven't touched anything ever since I sealed the cable plug on the RD. No issues with water ingress nor with cables coming loose. I'm riding the occasional cobbled road, which we got a lot of here.
Very little battery use, which is a pleasant surprise. I'm using branded higher quality batteries. Well, I like to believe that they're higher quality at least.

I will say that while it shifts fine, I'm not blown away by the shifting performance. It's okay for what it is, but my Campy 12sp mechanical is still in a different league in comparison. And the 11sp Ultegra that I rode on a rental bike was better as well. I consider myself fairly experienced in how to set up a groupset. I've been doing this for around 15 years. Maybe it's because I'm running an 11-34 cassette which is the extreme end of what the RD parallelogram arm/upper pulley can track well.

Man, i wish you all the best and hope the group continous to perform...thats how it should be....!

I ended up installing a spare ER9 groupset on my older SPCycle SP-027D frameset. Despite having a few quirks with my first ER9 bike, I think I've ironed out most potential issues. I was planning to save the groupset for a future bike build, but there's not much that interest me right now.  Plus I think semi ICR bikes running electronic are as hassle-free as it gets when it comes to maintenance and travel (my headset is solid like a rock).

This bike was easy to convert to electronic compared to my ER9 TFSA frameset. There was ample space to route the cables and battery holder. Only issue I had was getting my shifters installed properly on new 38cm flared drop bars. LTwoo has the most convoluted shift clamp screw. I also swapped in a new set of EBL brand 2x14500 batteries. They seem to be working well on my other ER9 bike, compared to the Skywolfe batteries I was using previously (both purchased off US EBay).

One strange thing is the ER9 FD on this frame hasn't asked for a firmware update. This ER9 FD is running ver 0.0, while my other ER9 frame is on ver 1.2 I believe. Also I'm running 11 speed 52-36t/11-32t on this frame, while my other frame is running 12 speed 50-34t/11-34t. When set to 11 speed, the fine tuning values were way off. I found it really strange, though I was able to adjust it properly. I also have a chain catcher on order, I don't trust non-Shimano FDs to be chain-drop free.

Anyways, I'll report back once I get a few kilometric miles on the groupset. We'll see if my bike implodes with all the shifty AliEx components I'm running!

hi folks, I'm a relatively new to building a bike myself, and in the process of doing so I've ordered the LTWOO eGR. Additionally I've ordered a cassette 12 speed 10-44, but the LTWOO eGR states that the supported gear range is 11 to 46, so I'm wondering if this will work?

[jonathanf2]

I've installed 2 replacements and these have been working fine, but that's on under 500km together.
the worst thing in all this is the behaviour of ltwoo. a beta product with a ghosting manufacturer is just bad news.

Since you have access to other ER9 groupsets, have you tried other cables and battery holders to narrow down the issue to the RD being completely dead?

At this point why not just order a spare ER9 RD? With the coupon deals right now, it'll probably be under $130 USD. Time is money, I'd rather be back on the bike.

wow, finally the "official" LTWOO store ships to Germany so we can benefit from the lower prices too.

[Serge_K]

It's definitely not a problem with cables.
We indeed just bought one on AliExpress, came to cost 145 EUR, not quite 130 USD, but still a good backup to have.

Well, we have matched all the aliexpress prices on the ltwoo products and are directly in Germany..
Now, as we have dropped the brand they seem to sell directly..
It also helps not getting in trouble, as the electronic products may get inspected by patent lawers soon?
Who knows...
But at the end it does not make to product more reliable and if they really start selling via aliexpress directly as the manufacturer they do destroy loads of possibilities for the future, as the market does not forget this behaviour...

so you matched the prices but as you dropped LTWOO from your website no one can find this nice deals online?
or am i just too blind to find them?
