Need help with compatibility on Shimano Di2 TT components
Moderator: robbosmans
I'm building a tri-bike and currently have Ultegra 8050 di2 front and rear derailleurs. So now I need bar end shifters along with brake levers/shifters for the aero TT/Tri cockpit. I'm looking at Dura Ace ST-R9160 Di2 (current generation) brake levers/shifters along with Dura Ace SW-9071 Di2 from previous generations. Will I have a compatibility issues running three different groupsets?

There are very few incompatibilities among Di2 components. I only know of three:
- Dura-Ace 7970 pre-dates E-tube and its components cannot be mixed with any other groupset.
- A mountain rear/front derailleur cannot be combined with a road front/rear derailleur.
- An Ultegra 6770 10-speed front/rear derailleur cannot be combined with an 11-speed rear/front derailleur.

No they don’t. Read my statement above again. Mountain derailleurs can be used with road levers, but you cannot combine a mountain rear derailleur with a road front derailleur.miltmaster3 wrote: ↑Tue Sep 03, 2019 1:18 pmThe 2) work perfect ( road - mountain) as long as it is e tube
