I just got the reply from my China manager, he said that from the photo it’s seem not like Aleoca Bike, so he is not very sure the shape of these hanger.
The hanger parts also need to merge the frame shape, thus, he suggests that for No.1 and No.2 you might let us know the bike model name, and also just double confirm that No.3 it’s the DaCoras bike? From my side DaCoras it’s the single speed fixie bike.
