Team 116 has posted designs of their 2002-2004 era 2-speed, crash shifter. While this specific design is now outdated (Bosch drill motor not included in 2005-2007 KoP), variants of this design are still used (379's 2007 shifter was based on this, as well as several other "descendants" of this transmission).

In 2007, Team 116 used the AndyMark gen.2 shifters.
