Rear Derailleur
#1
Please help me understand the rear derailleur. Does it contain one spring or two? Both the cage and the pulley are "spring loaded", I am trying to understand how this works. Thank you very much for answering.

There are 3 springs in a rear derailleur.
One in the cage pivot.
One at the mounting bolt. ("B" axle)
One in between the parallelogram.
