@StiffWeenies: Is there anyway to know which one we're buying when ordering a groupset from Sensah on AliExpress?
The linked video is pretty much the only piece of content I could find talking about it.
Sensah is still niche in China and everyone who wanted a groupset has bought one already, so I don't think that there will be many Chinese forum posts touching on it either. Everyone is just waiting for the hydraulic brakes like on this forum.
Either way, Sensah doesn’t really serialize product iterations the way big brands do e.g. FD-5800 v. FD-5801. The only way right now to know for sure is by contacting your seller but that's provided they know about this very recent update and aren't more interested in offloading old stock.
