I also tried it out on the road today for a 137km ride, and it's really cool. It even fixed a small rubbing I had before with the manual trim without touching anything else.

Is this available via firmware update?

I'm on v0.1.7 and if I remember correctly it was updated w while back. Maybe autotrim was available but nobody noticed or maybe it was always available in the firmware but there was no way to turn it on and it was added with a recent app update

at the beggin of ltwoo it was there. then they had legal issues with shimano, so they removed it. i waited 3 years for them to put it back. by chance i logged in and they put it back in. i didn't do any firmware update. it was probably added in some app update

then I hope Ltwoo can give an update "continuous gear ratio shifting with a single touch" feature.
In Shimano, this feature is called **Synchronized Shift**.

Hey, did anyone encounter the issue where RD is stuck on 0.0.1 firmware version and does not see any updates?

I tried resetting the RD, resetting and reinstalling the app, unpairing and repairing the RD, reconnecting, using different network but nothing seems to fix the issue. 80 designer store where i purchased also does not seem to have anything that could help me.

One of my ER9 groupsets is stuck at a lower version number but luckily it received the auto trim groupset.

Similar situation here, I have an eR7 and I can't update it past v0.1.4. but it does have the "auto half gear" aka auto-trimming option.

I've switched on this auto trimming and it looks the chain is rubbing. Do I need to setup FD one more time?

What batteries do you use? Ive had aimilar issues when i tried using 1000mah instead of 800

Ordered another set of 800 batteries and now it works. So something must have been or gone wrong with my first set of noname batteries.
Bought a set of Keeppower 14500 batteries and now it works fine. Just did a 150km race this weekend and yesterday 90km of training with no issues what so ever.

Hello there,

I've gotten into the game and thought it would be a somewhat easy ride, but I'm no facing a major issue.

Frame: Hygge Carbon S
bottom bracket: BSA Dura-Ace
Crank set: r7000 150 2x11
and I'm trying to pair that with an er9. There's a video on youtube with this combination and it's working - for me it's not. I already adjusted the FD to the most outward setting, but it seems like there's another underlying issue.

Do you guys have an idea? If you need extra picture I'm happy to deliver them, because I'm honestly lost at this point.

Thank you for that information!!
I am very happy. Tomorrow I will give it a tryn

What firmware version is it?

I'm interested in getting a V3 (I'm on V1) but only if the (old, wired) EGR rear mech is compatible with the shifters/rest of the drivetrain (no interest in 1x or the wireless stuff).  I am already running a 36T cassette with V1 and the "regular" V1 derailleur but am tempted by the new levers and USBC charging. I haven't seen a discussion of whether the "old" mechs are compatible with the new front mech and shifters.
