What is the difference between Long, Medium and Short cage derailleurs and what application would you use them?

3 rings in front=long cage
2 rings in front=medium cage
1 ring in front=short cage

Basically the longer the cage the more ability the rear derailleur has to take up slack in the chain when shifting front chainrings.

It all depends on how many chainrings you have on the front. Most MTBs come with three chainrings... a three ring set up would require a long cage, but with two chainrings (many people lose the big ring in lieu of a bash gaurd) you could get a away with a long or medium. The advantage(as far as I know) to shorter cage derailleurs is less material to damage/bend/break.
