I've had that, too. But other than the surface finish wearing away where the chain rubs, is that really an issue? It's really only cosmetic, I suppose. I didn't have the impression that the chain would wear through the FD cage.

Yeah I guess it's just cosmetic. I did try seeing if I could fit a Shimano skid plate, but it doesn't fit. I heard Wheeltop EDS TX users were able to fit the skid plate onto their FD.

Bad news, gents. I just received my eR9 from the choice purchase and it is NOT the new version. Definitely the old version with the magnetic charging on the rear and the old FD without USB-C charging. Oh well. It was still a great price. Now I gotta think about whether I want to keep it or deal with a return.

I just had a chat with Ltwoo Official Store. They said they were selling the new version and are sorry somehow received an old one. They said I could return or exchange and get a new version. I may go ahead and try to do that since I'm not installing this on a frame right now anyway.

More like they were hoping you wouldn't notice!  ;D

Is there any confirmed information about the rx9/erx 3rd Gen. RD?
We all know that the 1st Gen RDs died, but we do not know why.
Has LTwoo ever given the technical reasons for that or at least informed that they have solved the bugs in the new 3rd Gen?
Has LTwoo ever admitted that there was a bug in their RDs?

To each his own, but I'm more interested in what Wheeltop + Rotor can come up, that has the potential to be really good and give the 2 patent spammers some problems down the line.

Apparently, even in China, Ltwoo has a bad reputation, with people complaining about reliability issues and poor customer support. I thought it was a Western thing, but no.
They sell RDs for 100$ a pop, we pay more because of platform fees & shipping, but as far as i'm concerned, the trend is your friend. If it dies less often, whether it's because of better soldering, or because someone is doing voodoo on every batch that comes out, as long as it works, i'm happy. I wouldn't expect a chinese factory to acknowledge mistakes, but as long as they improve the stuff, i'm game.
Sram released a cassette that retails for 615 eur, so at this point, out of principle, i'll buy chinese. My friend runs DA di2. if he crashes and trashes his RD, i wonder how much it will cost him.

I've been talking to Chinese cyclists on social media almost daily and they also prefer having more reliable products and customer transparency. Shimano is quite affordable there (more so than in the west), so the comparison is always I can get Shimano for this price, why buy something else? I've also learned cycling is quite a young sport in China and we can thank the pandemic and social media for really kicking off interest in the sport. Many young people apparently saw cool photos and at the same time liked the idea of being outdoors. I've also learned cycling groups has been a big trend for dating!  ;D The huge spike in Chinese products and innovations we're seeing today was helped in part by cycling influencers! I think there's a lot of domestic pressure on LTwoo to improve across the board, so it's a win-win for us.  :)

I know this thread is about Ltwoo but do you hear much about Wheeltop?  Have you tried Wheeltop?

I'm following Wheeltop's account on one of the Chinese social media outlets, but I think they're in a similar boat as LTwoo. I think there is growing interest in Magene's upcoming groupset. The allure there is that they will have a fully integrated product line similar to Apple and the hope is better all-around support.

Does anyone know, if there is a chance to buy just die brifters (ER9) anywhere?
I guess I f... up mine, while reinstalling the grub screw. The lever body fell out of my hand an now the attached cable ist at least twice as long and the Fd doesn't shift anymore...

ER9 or just the regular R9? Contact 80 Design Store, I've bought small miscellaneous from them a few times and they always deliver.

I think 80 Designer Store did have a listing for them. They are currently just out of stock for the ER9 hence you cannot find their listings anywhere (except in your orders if you ordered that specific item before). So yeah just send them a message and they let you know if and when they can send you one.
Slow on the climb. And everywhere else.

Anyone know if ER9 RD is supposed to have a charging port? The FD clearly has a USB C port, but is the RD supposed to as well, or does all recharging occur thru the FD?

Old version had magnetic proprietary charger on RD and nothing on FD. New version supposedly has USB-C port on the FD but no port or magnetic charger on RD.

Can anyone share pictures of their front derailleur from the front in the hardest gear? Im loosing my mind here trying to get rid of the rubbing but the cage just seems too narrow. It looks like it's bent inwards at the bottom so it always rubs when I'm in the smaller cogs in the back and the chain sits lower. In big/small the chain barely fits in the cage and it's rubbing on both inner and outer plates
