Hi,
I have a Shamano XT FC-M780 crank on a touring bike, the rest of the bike has Ultegra 10 speed with STI shifters.

I am looking at a XT FD-M781 front derailleur and hoping I can shift it with my STI shifters but worried that the
Cable pull will be too far off. Does anyone have experience or recommendations on this?

The M781 uses the new dyna system which I think has different cable pull requirements than the older M761 so if the M781 doesn’t work could the M761 work?

If none of this works is my only option bar end shifters?

Thanks in advance for any advice.
