Will there be a 105 Di2?

What makes you think 105 Di2 is coming? First news here. If you look at the brand new 2022 BMC Teammachine lineup, it’s quite clear that Shimano is gonna release the new Dura-ace, Ultegra and 105 (yes 105) groupsets in Di2 versions, probably in the next weeks, all together.

Do you need to update firmware for Shimano Ultegra?

DO NOT UPDATE FIRMWARE using Shimano e-Tube software v2.6.0 or later if you are mixing an FD-6770 front derailleur and a RD-6870 11-speed rear derailleur, or a FD-6870 with a RD-6770. The problem component is the battery (external battery mounts SM-BMR1 and SM-BMR2, internal seat post battery SM-BTR2.)

Can a Shimano Ultegra be used as a front derailleur?

The 11-speed Dura-Ace 9070 and Ultegra 6870 rear derailleurs are designed exclusively for 11-speed rear sprockets and 11-speed Front Derailleurs. Shimano does not provide a way to recalibrate/reprogram them for a 10-speed setup.

Can a Shimano Ultegra be used with 11 speed sprockets?

If you have 10-speed wheels and 10-speed sprockets, you should use the 10-speed RD-6770 rear derailleur and a 10-speed FD-6770 front derailleur. Similarly, a 10-speed RD-6770 rear derailleur should not be used with 11-speed sprockets. There will be chatter in some gears, and there might be slow-shifts or self-shifts.

Is the Shimano Dura-Ace Di2 electronic shifting compatible?

Important Notice 2014-07-14: There is a compatibility issue with Shimano e-Tube software/firmware versions v2.6.0 and later that prevents 10-speed front derailleurs (FD-6770) from working with 11-speed rear derailleurs (RD-6870) and 11-speed front derailleurs (FD-6870) from working with 10-speed rear derailleurs (RD-6770).
