If you zoom in you can read the plaque, which explains that it is 12x 12:60 (1:5) reductions, totaling a 244,140,625:1 ratio. If you turned the input at 100rpm, it would take 4.46 years for the small wheel to complete a single revolution.

Maybe if we could get the SIM-CHICKEN-WRANGLER consortium to use this in their drive design next year, that would open up the doors for some other teams...

Nice! A couple of years ago I built a 59000:1 gearbox out of legos as a demo for my FRC team, but this is even cooler.
