6700ST shifter with 7900FD
I know the compatibility chart says that 7900FD should only be used with 7900ST, but has anyone done 6700ST with 7900FD? Things are sometimes different in practice.
I've a full set of 7900 but left brifter is broken and was thinking of getting a set of 6700STI instead of 7900, which are twice the cost.
Any helpful input would be greatly appreciated.
