an older Nexus flip trigger with a modified unit to handle the forward and backward shifting. IT acts just like a ratchet. Forward a click, up a gear and it returns to position, forward again and it goes up a gear and returns to position etc. Go backward and it goes down a gear and returns to position etc. You get the idea. These are THE BEST Nexus shifters to modify. I used this shifter on my Flying Falcon. I built a whole new shift stick out of bar aluminum. It looks like this guy just took the plastic paddle off the shifter and replaced it with rod and linkage. VERY COOL setup i might add.
