I"ve dicided it's time to upgrade my rear deraileur. My question is...short, medium or long cage? What's the difference?
I became insane with long intervals of horrible sanity.

Short answer: if you use all three rings on the front, long cage.. If you use two or one ring medium cage.

Short Cage will give you more clearance. The whole ring thing is a myth. short cage will work with any ring or cog choice.
 
I used to run XTR long, and now do XTR short

^Of course it'll "work" , that wasn't the question..  If you're using a short cage and accidentally drop into the granny gear when you're already on the small cog, drop your chain, and die, it won't work so well.

Nah, not on a long. The thread I posted gives a detailed explanation on why a short cage isn't a great idea if you use all three rings, the reason I posted it was so I didn't have to waste effort on something that's already been beaten to death.

Long is allegedly supposed to give you better shifting, short definitely gives you more clearance.  You don't really need the clearance down in without rocks and logs.  Buy what is cheaper.

^that's weird, I've always read that the shorter the cage, the faster (or better as you put it) the shifting.

i guess it depends where you ride. if you stick to WTA i guess you dont need short.

Not fighting, just trying to stop the spread of bad info. Couldn't care less about PEB's opinion.

Bugman, Another MYTH about SC is that they can't be used w/ 34t, dont believe that either... My suggestion to you is to not believe what we say.. because i like giving "bad info" and just call an LBS to get your "good Info".
