Sorry to be the give you the news but there's now way this will work. The 7970 is the old, 1st generation, Di2 set-up. When The Ultegra 6770 series came out they switched everything to the Etube system.
If the software is up to date and you could just use the RH brake shifter in synchro-shift mode and not bother with the LH shifter - this is what I do
You''ll also need a junction B box to to connect to your existing system (unless it already has a 5-port Junction A)0 -
hey up steve,thanks for taking the time to reply
thought it was as much
got a new left hand one if you like (four pin)for sale 0 -
Ha, I'm on etube and made my own satellite shifter by breaking down a broken STI for the electrical bits... but thanks for the offer0
