I am looking for some advice from the helpful folks here....

I have some new DA Di2 10spd STIs, will these work with cables, rear mech, front mech, batteries from the new 11 spd?

Thanks

    I am pretty sure the answer is no. See also article below, section on compatability. Between 7970 and 9070 they changed all the cables etc (going to the smaller diameter cables used on ultegra di2) So 9070 is compatible with first generation Ultegra but not first generation Dura Ace

    Mccaria is correct, there is no compatibility between 10 and 11 speed Dura Ace Di2 due to the wiring changing.
