Hi, I'm hoping some of you folk may be able to help me out on this one. What it is is i've just bought a new pair of xt 770 10 speed shifters ( not through my door yet) and I'm unsure if they'll work with the mechs I have in mind, the new xt ones m786? Are the xt m770 10 speed in the dyna sys range as in the pic of my shifters there isn't the D on the right hand shifter. Hope this makes sense cheers Rob
