We upsized the shifting cylinder and removed a stage so we could shift it into neutral. We routinely loaded with with 200-300 pounds and were releasing it.
We expected it to break, and it did. The shifting pin sheared and the dog gear rounded off the ears and the pocketed slots twice during the season.
The drivetrain shifters were installed and used as they were meant to be. The did not fail at all. In the off season we went in and had to change out the dog gears because the ears had rounded off.
We used encoders on them and had no issues.
Used as expected, we would recommend the gearbox to anyone.

This is helpful, thank you. Any other comments from teams with field experience with Sonic Shifter would be helpful. (We are already familiar through direct experience with several options from other vendors) I appreciate the input.
