well,
they only respond if you order, otherwise, you are ghosted.
They basically do not care if problems occur..they fail sending me documents...we offered to translate the app to germany, no response.
They promised so many things which did not happen....
i am selling off my grt stock for low prices...if anyone wants a groupset, i will offer better than aliexpress prices including shipping, i just want to get rid of them..even mechanic groupsets work fine...

Are you testing several EDS TX groupsets to become EU/DE distributor?

I use my ltwoo er9 with hammerhead karoo2 but the battery level doesn't seem accurate or granular enough, only displaying low/mid/high.

Only the ltwoo app gives the exact percentage.

Have you tried using another charging source?

Some powerbanks will auto-cutoff moments after you connect and will result in the unit draining instead of charging. You need to find a steady USB power source or a powerbank that works.

I posted about that before. originally i was trying to charge with a powerbank, but quickly realized it wasn't working. So yes, i've been using a wall socket with different high quality usb chargers and so on, i'm confident the issue is with the group / RD and not the juice. Also, i've handled 5 groups, i have 4 at home currently, so i know what works and doesn't, what should work but doesn't, and so on.
Ltwoo has asked if i have ridden in the rain, so presumably the charging issue has been linked to water exposure, which could explain why the new version has a USB C port in the FD. I'm speculating, because they're not exactly forthcoming w info, but it's the first time they ask a question.

For those with garmin devices, you can link the er9/erx w your head unit. tells you the level of charge of the battery, as well as which gear you're in, it's very neat.

ask them
Farsports made handlebars that won at the olympics, i doubt they work with fakes.
Leon is the OEM for Elite wheels, i also doubt they work with fakes.
Peter is a good guy, i dont think he deals in fakes.
That said, i've never paid up to get DT swiss hubs, so i really dont know how prevalent fakes are. What i do know is that most OEMs are using hubs either unbranded (their in house hubs), or the likes of Novatec & Bitex that, for all intended purposes, are replicating DT swiss without calling it DT swiss. Which is why i've never paid extra to get an actual dt swiss hub.

Shwalbe one, gp5000 or vitoria corsa depending on the bike and on the costs at each moment. but I always buy them below the 40€/tire mark. I think more than that is actually "trying to be pro when I'm not".
Then I use some TPU tube whatever is cheap
