Bike Shifters Won't Shift - The Most Common Cause

I take apart a trigger shifter and show the most common reason why old shifters won't shift. This applies to both mountain bike trigger shifters as well as road bike STI type shifters. I fix the shifter in the video and include links to a couple videos showing how to fix these types of shifters without even taking them apart.

Here are some of the videos I have done on fixing stuck shifters:
