I must be lucky/special.
Has anyone written the 2 sellers and asked why they can't/wont sell to customers in the USA? Since one of them sold one to me, perhaps they can be convinced to ship to the USA.
Based on youtube videos i've seen, L-TWOO has removed features that were patent pending. The auto trim is one that comes to mind. But Wheeltop seems to be much more reckless about that (I think with Sram related features especially, I think?). I'm not interested in that group so havent been paying close attention, but that's the impression i got. And the US is the land of lawsuits. And US cyclists keep complaining that road cycling is dying there, vs Asia is on the rise, and Europe is its birth place. And Sram is affordable in the US, while it's not in Europe.
So that's my 5 cents.
What i dont understand is why these channels are touting wheeltop electronic as the di2 killer when it's worse than l-twoo's erx in more ways than 1 (worse app, no garmin integration just to name two), and the er9/erx just works great, and having installed 5 and used 2, it feels premium alright (the rubber on the hoods for example, is great).
