My take is that some of the criticism of Lwoo is unfair. Luke (trace Vello) admits that there was an issue with the trifox frame where the FD hangar was moving. How sure is he that the FD did not sustain damage due to this? The other issue is some persons are clearly purchasing a beta version. At the time of their purchase Ltwoo had not released hence it was not sold on their official page . Can Ltwoo be blamed for persons who were part of its beta testing, turning around and selling the product they were to test? There are simply too many variables, not being properly considered. I have 11 speed DI2 and I know there is an issue sometimes when you use the app, even after properly disconnecting, the gears won't shift. You cannot re-enter the app, because its now unable to see the device.. Took me awhile to figure out it still thinks its connected and I need to disconnect Bluetooth (Even Shimano released product has bugs)
I am pretty sure in terms of timeline GC performance bought his after Ltwoo had announced but before they started selling from their official store. There should be a reasonable expectation that the product would be up to snuff at that point and that Ltwoo would try and control the sale of test units. I know Sram and Shimano have also had test units resold; but the communication that those were test units and asking for them back are the difference between how the different companies handle the situation.
Sram and Shimano also get criticized when their groups are used with non official components or are attached to frames that violate their published frame fit specs, which is why documentation is really important. Shimano does a meh job of this, but Ltwoo's is nonexistent. Those things should also include install documentation on how to prevent / minimize damage from moving or adjusting the front mech.
Additionally, I do think there is something to the somewhat charged language and frustration around customers being used as beta testers by these Chinese brands. They absolutely need a culture shift around their engineering to better test and validate their products. Ltwoo is just the latest in a long line of these kinds of issues. Other recent examples include Craft Racing and Elite's Drive wheels. I think this is problem with how their engineers are trained, but it needs to change if you want to build something as complex as an electronic groupset and win in the market.
There is so much potential here to build groupsets that can have profiles to run nearly any modern cassette offering up an expanded choice of drivetrain components, particularly for the 1x ERG where you have simplified the problem down to rear shifting. I only wish that group had a battery that was easier to access as well as a kit to allow for the compatibility with the accessory powerline from an e-bike battery.
