This is a badge bit (BB) that is part of the PEP curriculum. Completing this BB is part of getting the sand badge in tool care.

From the video description:
"Learn how to properly adjust the rear shifting on your bike for better performance! The bike I use for the demonstration is a Trek Madone equipped with a Shimano Ultegra derailleur."
To get certified for this BB, post a short video (2 minutes or less) that shows
- Before, During, and After shifter adjustments
