LTWOO ER9 & ERX - Electronic groepsets

[Bonka]

Have you used it? I just got my wheel and it doesn't work, the chain comes off on 1st and 12th gears....Shifter ltwoo erx

I contacted the supplier, and their technician said the pulley doesn't support 12 speeds and suggested a return. A 12-speed pulley is in development and will be available for purchase soon.
upd.
The seller also removed 12-speed support from the product.

It is completely free, now open it.

If only it were that easy 

I think mine is different to yours.
On the marking at the photo there were no screws. Probably they used glue instead of screws.

I will put some sealing on the outside to ceap the water away.

Thanks

Water leaks in through the motor shaft and the rubber seals, not through the housing. What version of the derailleur do you have?
I actually took my front derailleur apart and it was glued together. If you're careful, it's not a problem and everything comes apart.


I see that in the v3, well then yes, the weakest point was the charging port, it was removed, but if you are going to really flood your switch, then I recommend disassembling it and applying varnish to the board.

I've already tried different pulley positions, but nothing changes. I think it's a mistake that it's not narrow-wide; then it would work correctly. But I still don't understand how everyone installs it and gets it to work correctly.
My transmission worked perfectly throughout the entire range before.

It's not really necessary to have unless you're trying to push a bigger cassette range on the stock cage. I would have preferred using the new LTwoo OPSW, but I had issues trying to remove the cage on the V1 ER9. So this is the next best solution.

Ok, thanks for this information.

I have V2. I already tried to open it using a knife, without success. Maybe I will heat the case and try it again.

I don't see a charging port on your rear derailleur, as far as I know it's a v3

For my front derailleur, I used metal spatulas, heat and alcohol, and gradually I was able to separate it, don't be afraid to use force.

No, it´s V2. I bought it in Dec 24, V3 wasn´t available at this time. I also had contact to the technical support, they confirmed it´s V2.

Dear friends, please help me with my front derailleur setup. Either the limits aren't working properly, or I assembled the FD incorrectly. Limits don't go below 13 and don't go above 69, so I can't set my FD perfectly. I can change these values, but the shifter cage itself stays put. I don't understand this, because there's still some space in the cage, it doesn't touch anything, the motor just jerks and stays put. Also, if I set it to the maximum (69 limit), trimming up doesn't work (as if something is limiting it). Has anyone else encountered this, or do your FD limiters from 0 to 100 work fine?

the lowest mine goes is 2. didn't test the outer most position but it was more than enough. Are you sure the cage is not blocked by the chainrings?

I'm sure my derailleur is now removed and located separately from the bike.

I see there are new brake calipers? Are they lighter than the V3 calipers? No longer need funny adaptor plates?

Then I have a V3 groupset. My rear derailleur model number is RD-ER1201. I see there are now RD-ER1203s. With both regular and OSPWs. What's the difference between 1201 and 1203?

[nick82]

can you unpair the entire system somehow? i have a problem where at first the fd just makes clicking noises,  after a few minutes or maybe after going to sleep and waking up again its usually ok for the entire ride but last week i did a group ride and i didnt want to make people stop while i fucked about and had to do 50km stuck on the 34t chainring.

im going away for a month next week but after that if the problem persist and pandapodium arnt any help i might just have a local shop replace it with 105di2

I'll answer this myself:
After rebuilding the FD, I misaligned one gear by one tooth. Now I've re-aligned it and it seems to be fine.
I noticed it a year later because I installed a power meter, and it has a different offset. With a regular spider, those limits were sufficient, and I wasn't aware of the problem.

now i cant connect to the rd via the app if its logged in, if i clear the data i can skip the login and adjust most setting but i cant try and update the fiwmware. fucking piece of shit

Hi guys, after few months without any problems i have one with Er9 v1;/ Last ride was in wet condition, after ride cleaning etc, RD and FD was warking fine, next day also but yesterday totally dead ;/ Battery ok, FD ok, shifter ok, cables ok (i have tested with second ER9), only RD is dead, no reaction when plug charger etc (before led was blinking). Probably water do some mes ;/ This is v1 so in this case have someone info maybe what happend with maainboard or where water could get into RD to protect it in the future. I have the RD wire contact protected

Also will v3 RD work with shifters and FD from v1?
