LTWOO ER9 & ERX - Electronic groepsets

[Unknownftp]

I just saw this! LTwoo is releasing a fully wireless ER9 groupset for folding/compact bikes. I'm wondering if the upcoming ER7/9/X will also go full wireless like the recently announced 13 speed EGR? LTwoo might be trying to get the jump on Shimano before they go 13 speed wireless? 

Found a live ali storefront for it. So hopefully the new gen EGR and etx are soon to be here for us to market test.

Hi guys someone maybe have replace lever screws ? This small (need open to bled) my are dead and now i cant move them :/

If you remove the lever, those set screws also have a hex key insert on the back side. This saved me recently

Does anyone have the LTWOO ER9 v 3.0 drivetrain paired with a ZTTO 12-speed 32T cassette?
Could someone share the micro-adjustment values they use for each gear in the app?

In my case, some gears tend to skip on their own (for example on bumps—actually two of them), and for the rest I feel like I’ve set things in a way that the chain doesn’t run straight over the jockey wheels of the rear derailleur.

Maybe if I copy someone’s settings, I can at least get closer to making the drivetrain run quietly 😄

Has anyone else had their ERX (newest version) front derailleur die from a firmware update? I was downloading/installing the firmware for the front derailleur and it cut out and subsequently killed my front derailleur. Nothing will revive the FD and I've tried absolutely everything under the sun to fix it. The app just shows "Front derailleur status is abnormal and cannot be used".

I'm at my wits end with trying to fix this.

I have the same problem. Have you fixed it?

Anyone knows if the new eGR groupset with the integrated battery is available yet? It shows on their website but I can’t find it on ali.

I'd probably give a month or two. I also hope replacement parts available. I was able to get spare batteries for my Wheeltop GeX which makes it almost as convenient as SRAM's removable battery setup. I just make sure to charge it, so no real need to swap it out.

[Ludo]

The non replaceable is a little concerning if the battery die after 2y, you junk the derailleur?

[toxin]

Surely it's a similar deal as Wheeltop, where the battery is replaceable with some tools and effort, but not hot swappable, like SRAM AXS. If for no other reason then because no western OEM would want to work with them if they can't sell their product in the EU.

I'm a little concerned about the battery capacity of the full wireless eGR. Gravel bikes tend to be ridden in more remote areas. I took my first gen eGR equipped gravel bike to the desert for a long trip and didn't charge it the whole time. That's with 2x 800mah 14500 batteries. Isn't the new eGR only 400mah with 1x battery? I hope it offers charging off a power bank or even a smartphone.

[Ludo]

Correct regarding battery capacity. Wheeltop is 800, didn’t check others

I have a Wheeltop group set. The battery needs charging every 2 months or so? 800mah.

I keep a shortened cable in my saddle bag that works using reverse charging on my phone.

For the long trip (two or more days) i use this mini powerbank https://it.aliexpress.com/item/1005007850830460.html pretty light too

New eGR not released for sale yet according to ltwoo store on ali

i finally took a video of the problem i have. the fd will respond but not shift, it will eventually shift properly but i dont know what causes it to "wake up" it always responds when plugged in and then stays working even after the 15 second timeout for a while. i just checked the battery and it isnt a loose cable.

i remember people complaining about the fd not sleeping and killing the battery i feel like they tried to fix that but its too agressive on some hardware revisions, i know there are multiple versions of the v3 fd because some can be updated to fix the single gear fine tuning and some cant (mine is one that cant)

i think the video should work now

Have you tried contacting ltwoo support? If not, contact them using a non-gmail email address (they don't respond to me if I contact them using my gmail email address, but they always respond if I contact them using another email address).

I didn't know there was a difference between derailleurs, which is interesting. I have an ER7 and it doesn't have fine tuning.
