LTWOO ER9 & ERX - Electronic groepsets

[lavistaa]

What support channel have you used please?

Didn't see all the questions until now!   I bought from 80 Designer Store which has been super responsive.   We got an erx first, had the issue wish they asked for a video of my mech not operating and then sent the new mech straight away no argument.  I've gotten a few other things from then since bit haven't had any new issues with the erx or anything else.  My erx is still perfect, just rode through a very wet ride here in PEI today with no issues at all. Haven't had to make any adjustments and there's only been one firmware update so I think whatever caused the failure before seems to have been hardware related and not recurred or fw related.  It's the "old" version, not the 2024 one.   I am running a 12 spd 11-36 Shimano cassette with it and no issues with capacity.  I do wish I knew if it worked with the EGR mech as I'd love to run a 40 or 42 with a double as I can with the now NLA Ultegra RX groupset.

80 Designer Store warranty update. Responses were pretty quick and they had to talk to LTwoo as well but yea they're sending me a new rear derailleur. They gave me a link to make a new order through their store for $15 which is probably for shipping and processing or whatever but yea looks like i'll be getting a new derailleur sent over

This was my (positive) experience with the same store

1090€ is from bike-components.de today

Anyone selling 105 di2 for 500 is either doing something illegal or not complying with their Shimano agreement as that is way below OEM cost (I'm a manufacturer and only sell legit Shimano stiff, we couldn't touch that number even selling at a loss).

I'm not sure the reason, but I would guess neither of those reasons. Maybe some other design decision, though. The Ltwoo eGR has mega spring tension. It's impressive how stable and taught the RD keeps the chain. The eGR doesn't have a clutch, but it retains the chain WAY better than my Advent X 1x10 that did have a clutch.

You haven't, by any chance, seem of the ERX brifters will control the EGR rear mech?   I am using an 11-36 with the erx but would love to bump the rear cassette up a bit.

Yeah, I can check it next time I'm out in the garage, headed out to dinner currently!

Any luck with testing the erx/EGR cross compatibility?

Another update... swapped finally swapped out the warrantied derailleur and everything is running as it should be. Also a buddy of mine just got a Canyon Ultimate that came with 105 di2. 12 miles in and his right shifter button was sticking just like my er9 did. So yea there ya go. Happens to Shimano too But yea, would really like to applaud 80 Designer store. Responses were ridiculously quick, everything was taken cared of and a replacement was shipped out in no time

Also had good customer service experience with 80 designer store sorting a broken GR9 shifter.

I replaced my cheap ZRACE chainrings with a new set of Ultegra chainrings that I bought 2nd hand. I was never fully satisfied with how the FD performed. Now it's much better. Still not particularly quiet and it could still be smoother. But very reliable.

what happened to the blue edition? it disappeared. we don't hear anything about it anymore.
do you have any news?

[toxin]

The "blue edition" was a prototype of the 2.0 that was replaced almost instantly and they've done like 3 iterations since the one they had on bike shows. Just not selling anything yet.

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

I'm working on getting the fd tuned properly. When I'm using the adjustment button it seems to move in and out instead of just one direction. Does anyone have any tips? Should I be in the first click of going up to the big ring, or the second click trim position?

Adjust for the 1st click. I only use the second click to adjust when in the big or small cassette cogs. The first click should already be free of FD rubbing. Plus the app doesn't allow for trim fine-tuning directly from the app, trim only happens manually when pressing the left shift button.

I wish LTwoo would implement some new features, but I'm sure Shimano and SRAM have some software patents that keep them limited on features. Either that or they don't have the software budget to do so. I also notice Wheeltop is getting more OEM groupset sales, whereas I don't see any bikes in Asia getting LTwoo electronic.

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

response time was pretty quick... I got the standard checklist too but told them I went through all of that already and told them it started happening after some crazy rain. They got back to me in hours saying they'll contact Ltwoo. In about a week they sent me a new custom order for $15 for shipping and in two days, my new derailleur was shipped
