These SPD trail pedals design to have bindings that operate exactly like the XTR Race pedals in both performance and function. The main difference is that the pedal body extends fore and aft of the retention mechanism as a lightweight cage to better support the sole of your shoe.
Its open design allows muck to flow through, so it doesn't hamper the cyclist ability to engage or exit quickly. Other than the cage, the most significant design change is at the pedal body with larger flat platforms on the inboard and outboard edges to keep the sole of your shoe solid on the pedal.
The XTR Trail PD-M9120 Pedals come with SM-SH51 single release shoe cleats and are also compatible with SM-SH56 multi-release shoe cleats. They have chromoly spindles and spin on sealed bearings. The tension of the retention mechanism can be adjusted via a hex screw on the back of each pedal on both sides.
