LTWOO ER9 & ERX - Electronic groepsets

[Sebastian]

I might have missed it somewhere but how do we check the battery level of the shifters? (Cr2032)
I don't seem to see it displayed anywhere?

The app only reports the derailleur battery level.

I don't think that's possible. The (very brief) manual also doesn't mention anything AFAIK. Maybe this could be implemented in a future update of the companion app?

The app only reports the derailleur battery level.

if i recall correctly, the light on the shifters turn red when battery is at like 20%?

What bleeding kits does everyone use with their LTWoo groupsets? My kit doesn't fit the callipers and no store in town has a fitting kit.

I bought the full ezmtb bleed kits from AliExpress and they had the adapters.
IIRC some YouTubers mentioned that ltwoo requires sram style adapters.

Just found this amazing item on AliExpress. Check it out!

Hi guys, am I the only one that can't access the LTWOO official store on Ali? It seems that we can see items from them but only through Choice Store (concept from Ali). The reason I am asking is that the er9 is on sale through Choice, but it won't ship to Canada.

Seems to work on my end at least from the USA:

Just in case it helps, there is also 80 Designer Store, which generally has better prices than LTWOO Official Store. For example, I'm seeing eR9 No Box No Battery for US$ 464 for at the former while US$514 at the latter. (I have no idea about their shipping policies though.)

[Benbenben]

Yes, 80 store usually has better price, but with the current sale, er9 is down to 414USD from LTWOO via choice. That would have been a sweet deal with the 50USD coupon.

Yeah I have this problem too in Canada. I noticed the price from the LTWOO official store is substantially lower than any other, so that's too bad.

So I finally got the matching bleeding kit and got around to bleeding the brakes. Rear brake went completely smooth - was done in 5 minutes or so.

Front brake however - it seems like the brifter is leaking air somewhere, when I pull on a brake lever, there's a sloshing noise, similar to sound you get when you are pushing in a water bottle. The sound is coming from the top of brifter, both the oil and air screws are fully tightened. Any ideas what could be the issue? Don't have a video at the moment, apologies.

I've pulled the trigger on the eR9 groupset, do you guys know if we can swap the pulley on the rear derailleur for an oversized one? And if yes wich one to your knowledge.

Looking foward to try the eR9. I have the RX mechanical and no issue with it.

I believe LTwoo and Sensah rivet on their pulley cages so they're non-removable. At best you might be able to get away with 12t and 14t jockey wheels with the stock cage. I use these POM jockey wheels from Fovno with steel bearings on my gravel bike. They spin smooth with no issues even with mud and dirt:

Oh, I mine had this issue too.  I needed to replace the olive (where you connect the hydraulic hose to the shifter) and that fixed the problem.  Hopefully you can figure it out soon.

I have now done around 1.500 km with my er9 groupset. I had one single incident during a ride where I experienced lagging shifting with my RD where I had to push the button twice or three times to shift. I sealed the cable plug at the RD with silicone grease. I did nothing to the FD. It has been working fine ever since. After some minor tweaking here and there it does now shift very nicely. I'm very pleased with it. IMO for the money it's a no brainer. At least in Germany I got it for around 2/3 of the price of the cheapest offering for 105Di2.
So my verdict is: I'd probably buy it again for that kind of money. BUT I dunno how it compares to 12sp Di2 or Sram Etap AXS. Never ridden any of them.
