All...I don't know if this has been discussed yet or not (I couldn't find it) but I have just finished a DI2 build and cannot get the FD to upshift without sending it over the large chainring. I have 6770 FD with 9070 RD and Syrius chainrings. My mechanic thinks the chainring may be flexing too much? Not sure if it matters but the Syrius chainrings have "10-speed" stamped on them.

Has anyone had similar issues with these chainrings?

What alternative chainrings are working with 11-speed DI2?
