So I have a canyon endurance 6al with a tiagra group set and wanted to know if the new shimano 105 R7100 would fit my frame or is the frame only compatible with the 105 R7000. Help please
Why do you want to do this?
You might want to check with Canyon. I had a carbon Endurace with mech shifting a few years back and they didn’t come with the predrilled holes to run Di2 wires.
You could always go with Sram Rival AXS if you’re set on a electronic shifting upgrade.
I have a 2017 ultimate cf sl frame and it isnot Di2 compatible. Ask canyon, they’re online chat is very helpful. I ended up going with a used 11sp etap groupset.
I don’t think that’s a great upgrade. I’d get new wheels instead. That’ll make your bike significantly lighter and better handling. Plus, you’ll be more aero, too.

Yeah, that’s why I asked. That said I upgraden my mechanical 11 speed ultegra r8020 with an SRAM axs force/red mix with which I am very happy shifting is just much better on this bike (which is mainly due to the internal routing which made mechanical shifting poor). I had to do that though because my shifter broke and it would have taken months for a replacement

I should remember that one when I want to justify an upgrade to my wife! 
In that situation it makes sense to upgrade a groupset. Mixing Force and Red is a sensible move, too.
