There are a lot of drivetrain and front derailleur choices available these days. We have tested many combinations on our frames. The chart below lists combinations we know work well on the models listed.

Also note that the instructions on modifying the XX High Clamp Top Pull derailleur can be found here (it is a PDF that will download).
