LTWOO ER9 & ERX - Electronic groepsets

[kenderu]

Can I ask how did you paired your erx with your garmin computer?

I just added it as Di2/Electronic Shifting and it showed up.

I have received my er9 groupset, unfortunately my front derailleur doesnt work. I want to update the firmware but it doesnt go past 1 percent. Anybody who has a clue?

Do you have batteries in the battery? I found that it needed more power than just plug in the cable.

I have batteries in the battery

I can confirm with the latest firmware update, the trim options are now more refined. The front derailleur will decide the best trim position. I also noticed that they have fixed the incorrect gear selection showing up on Wahoo. It was showing 12 speed when in fact I was on 11 speed cassette. I cannot confirm if this is also fixed on any other head unit. It is still showing that the battery is low even when fully charged. Hopefully they will fix this on the next update. Well, it looks like LTWOO is certainly working on making the groupset better and better. Kudos to them!

I think what LTWOO should do is to allow users to manually set a two steps shift, by allowing users to manually configure the sequence of shifts, it would avoid shimano copyrights issues.

I can confirm that it also works with Wahoo although the display is somewhat lagging...

Just did my first semi-wet ride after installing my 2nd rear derailleur (after 2 months of not being able to use it). This time with dielectric grease on both derailleurs.

First ride, and the shifting was incredible. So far no issues with the grease. Hopefully this derailleur will survive the weather in the Netherlands.

Ltwoo was helpful with their customer support, however the process of confirming the issue, and shipping the new derailleur took a sizable amount of time.

I'm planning to build my e-gravel with this group.
Would you mind to explain the known issue(s) of the group, as there are already 30+ pages.
The "dielectric grease" intrigued me

The number one issue (and admittedly my only one) is water ingress. On my first set, after the first ride, I already started having issues. Note that I live in the enticingly moist Netherlands. After ride nr 5, I decided to add duct tape to the connections, which temporarily seemed to resolve all issues, until the 31st of Dec, when the rear derailleur died on me mid-ride.

The duct tape is not a full fix, and I personally only have one ride with the dielectric grease setup, but the latter solution seems to work for many people having this set.

You need to somehow seal the plug at the RD to make it 100% waterproof. Otherwise you're definitely gonna have issues. Silicone grease worked for me. Silicone sealant or Teflon tape could work as well, I guess. Other than that I had zero issues so far. This seems to be the most common problem.

I use this around the RD connector.

Have hosed down my bike several times with no issues.

[mirek100]

Is it possible to disconnect the connector if necessary wenn you use this glue?

[zerstorer]

Just use a light coating. It tears off when you pull.

Hello everyone, since yesterday I am the owner of the Ltwoo ER9 group and I have a question for the distinguished group about trimming - how does it work in your sets? It works fine on a small countertop, but on a large countertop it's like magic for me

[aramus1979]

Ok, thank you for the advice, and is it also the case that if the chain is on a small tabletop, you can use one half-speed, and if on a large tabletop, you have as many as four of these half-speeds at your disposal?
