W/o any warning my rear derailleur got sucked into my spokes. Bike had been flawless shifting. It happened when i was shifting from the large ring to the smaller. dropout is a mess. Hope my lbs can staighten. What can be done for this not to happen again? thanks.

You might want to check two things. Check and make sure your derailleur hanger is not bent. Your lbs will have a the proper tool to straighten it if it is bent. The second thing is to make sure you derailleur cage is not bent. Although, it may really be bent now that it had a little one on one with your wheel. Just a couple of suggestions!!
Good Luck.

Try to figure out the root casue. Why did a mechanical thing suddenly do a brain-fart? Typical causes are things like the chain being too short or the der./hanger getting bent when the bike is stored or laid down (always place it drive train side up), or a high/low limit screw not adjusted correctly. chances are great that the rear der. is toast. The hanger needs to be straighted if steel/ti or replaced if aluminum. By any chance did this happen to be a GT frame? Their aluminum hangers are total cheese, but replaceable. An OCLV dropout can be replaced for $70 + $20 shipping to Trek.
