I bought a m960 rear derailleur, used it for about 10 rides max, on flat ground its never been hit, I keep it clean and the bottom wheel fell off when i was riding 20 miles out into the Everglades! when it fell off the chain grabbed the back of the derailleur and twisted it into a distorted ball of painful walking!!! 20miles in the hot ass sun of florida. well my point it, should this derailleur have broke like this? or was it defective and will shimono reimburse me? are they guaranteed for this?

Call Shimano or take it to the shop you bought from and find out.

I ment do you know if shimano is good on there replacing parts? I got a guy on the phone who just cant belive the derailluer broke. I sent it any ways, I kinda wanted to know if i was waisting the cash ,mailing it to them. but thatks for responding any how.

Loco has had good luck with replacements from Shimano.

In my experiences, Shimano has been hassle-free when it comes to warranty stuff.

Something is wrong if the bottom pulley fell off. Stock, the derailleur has locktite on the little bolt PLUS a 'c'ring circlip on the end of that little bolt to prevent it from backing out should the locktite fail. Maybe some one at the shop was messing with that derailleur before you bought it. Like some one needed pulleys and they pulled them off that derailleur and ordered spares to replace them and lost the circlip. Not hard to do. I spent a long time with a magnet in the dirt of my garage floor looking for the one I droped.

OK shimano sent the xtr d-rail back to me, and did not fix it, the little clip did come off and the screew fell out, clearly there falt, from the factory. it cost me 40 bucks to fix it, so now I just know they are no good on there warranties.

Or perhaps the shop screwed up?
