LTWOO ER9 & ERX - Electronic groepsets

[cdamgaard]

Okay, sounds pretty reasonable. They did revert yesterday and asked for a video, so that is send and I assume they share with Ltwoo and then send me a replacement. Thanks for letting me know.

Do you have the issue where the adjustment seems to not move continuously in one direction? That's the other thing that's making it hard

If that happens, try adjusting the front derailleur physically on the hanger if it's still rubbing. The FD fine tuning can only adjust so much, you still need to align the actual FD properly. I sometimes find it better to adjust the FD while the bike is flipped over because you can see the FD and chain line much better.

a little update...
we have claimed a burned battery tray at ltwoo, which was bought directly...the tray burned while charging normally....
Ltwoo wanted pictures, which were sent..
Now, they want a video...we have asked in detail what the video needs to show..
Our customer is now not able to ride.
It seems that they have no intention to help us, but also do not shut the door completey...
This becomse more and more a circus..

I think it's a tactic that sellers use in the hope you will eventually give up. This was what OG-Evkin did when I tried to get warranty on my MTB frame with crooked BB shell. They keep asking and keep promising for months and in the end you end up with nothing but a lot of frustration.

Hi, how was the response time from 80 Designer Shop. I have raised an issue with a dead EGR, they quickly replied with standard checklist to check and then silence and no answers in a couple of days. Did you also experience long response time.
Thanks,
Christian

Once I showed them a video of the shifter not working there was a few days of silence, then they responded that the new shifter was sent. Gave me a tracking number and it arrived in about a week.

That's 100% what LTWOO did with me. After literally months of slow back and forth, where every time the goal post kept changing, i gave up. in the middle there was my reseller being ghosted by ltwoo and having to contact someone else at ltwoo. they essentially do their best to be unhelpful.

Well, i defenately will not give up...
and i am not afraid to make a youtube video about our experiences with LTWOO business tactic.

Had to replace the coin cell in my FD shift lever after roughly 35.000 shifts. The indicator light on the inside of the brake lever started flashing red. The weird thing is that I rarely shift the front and the rear shifter is still flashing green despite seeing much more use. I guess the coin cells are just not the best quality. I replaced it and it's good to go. No repairing necessary.

and be careful because paypal is not helping anymore on this. Latest experience with paypal have been very bad, a waste of money. Probably aliexpress is more safe now.

Is credit card any better at helping with disputes?

So I went and impulse bought some Zrace XG calipers for my Ltwoo ER9 groupset. Was wondering since the pistons are both 22mm but the Ltwoo ones are ceramic and Zrace is aluminum... has anyone here swapped them to see if they're interchangeable? Lol

I switched back to GRX calipers mainly because I found the XG pistons tend to be sticky after long descents. They could be better if they were fitted with ceramic pistons.

Good to know... yea the zrace were an impulse buy as they were like $55 shipped for a pair... Sounds like possibly the aluminum zrace pistons expanding under high heat? I might try and retrofit the ltwoo pistons in there and see if that works if i dont like them haha|

Or maybe i could try something like this

That could be a cheap solution if they use the same size piston. Have you measured the zrace ones?
If its a tolerance issue with zrace, then they probably won't solve the problem. I just ordered some grx400 calipers for $33 from ali to replace my ltwoo calipers. Couldn't resist at that price.

Trace Velo measured and said they were both 22mm? But i'm not sure...  I'm probably going to run the stock ones for a bit when mine get here and then if i'm not happy with them do the swap. I also noticed Lewis uses Ti pistons which is interesting! Never seen that before

Pair of GRX 400 calipers:
https://www.aliexpress.us/item/3256807394938962.html

These GRX 400 calipers cost almost as much as the Zrace XG calipers. Weight-wise GRX calipers weigh less than both Ultegra and 105 and there's no difference between GRX 400/600/800 other than appearance. I confirmed with the seller this comes as a pair. I have a set of these on my gravel bike and on long descents the pistons don't get sticky and they're Shimano quality.
