This invoked a trip down memory lane regarding the "old school" days of FRC shifting gearboxes. Aside of the DeWalt planetaries, only a handful of teams had shifting spur gearboxes in their drivetrains. The 116 crash shifter, the 33 4-speed crash shifter, the 222 ball shifter, the 45 dog shifter, the 716 dog shifter, etc. All of that barely more than a decade old. Newer FRC participants don't really how much of a game changer having spur gearboxes in the kit of parts was, let alone having COTS shifting options.
