The Shimano XT FD-M770 front derailleur is designed specifically to work with the Dyna-Sys 10-speed Shimano drivetrain. Dyna-Sys means closer ratios, smoother shifts and greater stability in the rider's pedal stroke. The multi-pull design allows for top or bottom cable pull. The cage is designed for greater tire clearance and the limit screws are angled outward to accommodate varying full suspension designs.
