THANK YOU for showing the BACK of the derailleur and the action the B screw takes against the spring tension! Many videos show adjusting the B screw, but no one ever shows what is mechanically happening on the back side. Thank you!!

Thank you, Calvin, for the clear explanation of how the B screw works, and for the rhymes at 1:17.

Thanks Calvin. This helped a lot. I completed my first build this year, a Velo Orange Passhunter. It’s set up with downtube friction shifters. It shifted ok but not perfect. Now that I made a B screw adjustment with your help everything is working perfectly.
