*UPDATE* Welp... after reading some back posts in this thread... I went and held the pair button to reset stuff... it moved the derailleur but would go back to original stuck position. Looked at the app and it still thought i was in the highest gear... What i did was hold it again and pedal the bike when it moved and it eventually dumped the gears into the smallest cog and now things are working again. Yea it's buggy. First time encountering this issue. I think TraceVelo had taken his apart and moved a thing at some point but this somehow worked for me just figuring out the software. Wondering if the new version is gonna be as buggy as this one...

Another ER9 issue... Yea anyone have any ideas? I've sent this to 80 Designer Store as well. They sent me a replacement rear derailleur last time when the old one had battery phantom drain. I also complained about the sticking button under freezing temps too a few months ago and have not gotten any updates but now it's warmer I havent had that issue so I dont mind as much. But now this after I cleaned my bike. Didnt even hose the derailleur. Hoping 80 Designer Store will be fix it...

Hi, I have been an owner of ER9 for more than a year now, but as the days are getting warmer this time of the year (for anyone living in the northern hemisphere, at least), I noticed that the brake lever action is changing very noticeably depending on the temperature. For example, I recently adjusted them to be responsive at around 5 ºC, but now that the temperatures are at ~15 ºC, the rear brake sticks significantly. I suppose this is not normal, and I am wondering whether anyone else has experienced something similar and if anyone has any ideas what the problem might be.

yea i've got the same thing too and don't know why but doesn't bother me much... I just adjust the lever reach adjuster to compensate

Where are the discounted 105 Di2's available? Anyone know if it's possible to get just the shifter+FD+RD+disc brake calipers+battery (minus crank, cassette, etc.)?

I'm curious too... Would be cool if it came without calipers as well as there are many aftermarket options now

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

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.

The only thing I don't like about the LTwoo groupset is the FD. Shifting is okay, but compared to my previous Ultegra/GRX mechanical FDs, it's nowhere as good. Also I wish the LTwoo FD had a skid plate, my FDs are looking worn out. I read Wheeltop users were able to fit a Shimano skid plate onto the EDS TX FD, but not sure it's possible with LTwoo.

I've actually been pretty impressed with the front derailleur shifting of my er9. Wonder though if it's to do with the shimano chainrings on the GRX cranks?

Panda Podium listing the 2025 'blue' eRX version in stock:

Wondering if they've updated stuff since Jesse Coyle ran them a while ago for Panda Podium to have enough confidence to put them on their site

Did you buy the one that's specifically 182g? I'm tempted, but I'd rather have a 12 speed version.

I've been running the 12s 11-34 in Blue for the past year and it's been decent. Also came in at like 230g

I wonder if moisture is getting trapped in your shifter assembly, which then freezes in the cold temps causing the shifters to get stuck? I do a lot of climbing and descending, so I'm constantly shifting throughout the gear range. At least in the 40 degree + range, it's not an issue. Maybe you can coat the shifter spring assemble with some sort of anti-moisture lubricant?

I doubt it's moisture and actual ice... the buttons were still clicking this last round. It just thought the big paddle was constantly being pressed. I think some thing is contracting at the cold temps that's not allowing the thing to return to where it needs to be? I've no idea... just gotta wait to see what 80DesignerStore and LTwoo say.

80 Designer Store has gotten back to me and I guess they're talking to LTwoo... i sent them a strava ride i did where the temps were around 32 degrees where the button got stuck and another ride a few days later where it was 55 degrees and the button was fine again. Waiting to hear back...

I actually think it looks pretty sick minus that massive hole in the seat tube

FYI, the eGR shifter is likely not immune to this issue, entirely. I've had issues with my right shifter (i.e. the only shifter I use since the eGR is 1x) being quite sticky. One of my buttons feels like it no longer has much spring back on the lever. It feels, to my finger feel, like most of the return force comes from the button itself. The lever frequently gets stuck near the button, but it's not really a problem because the button doesn't actually get stuck - it's just that the lever doesn't fully return to where my finger expects it.

Maybe the difference is that the eGR has a much more tactile and "clicky" button under the lever, so the button itself is just a little better at pushing the lever back. That's what it feels like to me.

Last year when I had the issue it was like you described where the button didn't spring back into the original position. This year since I've opened it up and stretch the spring like Trace Velo, the button returns but it still thinks it's being pushed. Something is contracting under the cold temperatures keeping it stuck and it happens at freezing temps seems like. Yea we'll see what 80DesignerStore and Ltwoo says. Responses are probably going to be a little slow seeing as it's Chinese New Year right now but I'll keep ya'll posted as I get updates...

The EGR shift levers are just slightly longer. The difference is barely noticeable (maybe 1cm), but you can feel it when riding the drops. The EGR shift buttons require more pressure to shift as well. They feel/sound more clicky. They are different enough they might be awkward mis-matching them with ER9 levers.   ;)

Good to know... I just shot a DM to 80 Designer Store to see if they have any solutions. Temperatures are starting to rise again out here but i'd rather not have to face this again next year.
