Just to confirm though. The EGR battery pack only has 1 cable port. You'd need a 2 cable port battery pack. Also is there any confirmation that the EGR RD will talk to an ER9/X FD if hooked up together?

this is how they work together

for those interested - the eR9 brake levers work with the eGR rear derailleur and vice versa, the eR9 rear derailleur works with the eGR brake levers

I also have an er9 without any problem with water. I have washed the bike several times. the only problem I had was with the fd, which from the first to the last gear had a problem. yesterday for the first time I noticed that there was probably an update and there are three levels of adjustment in the fd. my great suffering was finally solved. every time you press the shifter, depending on what speed you are in, the position of the fd also changes

I understand that now the front derailleur is automatically adjusted the same way as SRAM? Do you have a new update that introduces this possibility?

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

everything works precise adjustment of the front derailleur again eliminated the problem (very precise setting was the key to success). The half-speed gears work properly, but it's a pity that they are not automatic like in Shimano, they have to be corrected manually by pressing a button. Maybe the next update will introduce such an option. Thank you very much for help

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
