>>1327892Those dropouts and the derailleur hanger look to be the same as Trezure's. Trezure started out with A050 shifters as well. Might be from the same factory. Still cannot figure out to this day which factory that is though, but they share the dropout/hanger with Vilano bikes, who has confirmed production in China.
I keep forgetting to take new pics of Trezure on group rides so here's another repost.
