    XT 785 Front Derailleur Compatibility

    Just curious as to whether or not this derailleur is 3 ring compatible and how to make sure it will work with the shift system I have on my bike. Cable comes up from the bottom of my bike. Its a Cannondale Trail SL4 and I am looking around to prepare for when things break

    Thanks

    There is two different derailleurs for double or triple applications. So if you want to change you need a new derailleur. If you have XT shifters there is a little switch for 2x or 3x underneath. So those will not need to be changed.

    The 785 is 2-speed low-clamp.

    For three-speed you want either a 781 (high clamp) or 780 (low clamp).

    I converted from 3x to 2x and really like it. I ended up eventually replacing everything but the crank. But if you want to go 2x I would get started with just a 2x FD and remove the big ring. A 3x shifter (even the SLX that does not have the 2x/3x switch) will work just fine with 2x.
