I emailed Magene asking about Di2 compatibility (because I’ve read some concerning things about the clearance to the front derailleur) but they basically replied it’s compatible but will be improved with new QED chainrings (but I think their response is more general, not Di2 specific). The email is obviously translated but my take is that there’s some new chainrings that might be available on Magene.com right now but not on AliExpress yet.

Just something to consider for those who also will go for the Magene chainrings.
