First, where did it drop? Several things come to mind: the chain is too long, you are cross chaining and shifting to smaller cogs front and rear at the same time under power, your derailleur(s) is not adjusted properly (this includes placement of the front - check the required spacing between large ring and cage), your chain is too long. Wait, didn't we have this conversation before?

Stopped to help a guy from the La Grange ride this morning on Mulholland. These guys are real hammerheads who stop for nothing.One had crossed over the double yellow a half mile before and almost hit me going the other way. He had dropped his chain and it was wedged in tight between the chainring and the frame. He's beating on his rear wheel trying to get it out of the dropout all the while his buddies are racing by , some offering to help, but he keeps saying that he has it under control. Guess he thought I did cause he didn't have a clue. WTF!!! It was clearly evident that he had been cross chaining to the max cause while he was beating on his wheel the rear derailer was wedged in his spokes. This guy was about to cause some major damage. Finally we got the wheel out but the chain was stuck too tightly against the frame and again it had to calm this guy down or he could have ruined his carbon frame. He finally gave up and started calling for help since all of his buddies who had offered to help were long gone.
Any shifting system will throw the chain if you go too far over toward the larger cassette cogs before you shift the chainring. You can cause serious damage to delicate carbon frames. Use a little judgement in shifting and don't wait till the last minute to shift the chainring.
I don't think I'm gonna stop and help these guys anymore. All I get out of the experience is a good smearing of black grease. God, don't these racer types, that think they are such hot **** ,ever clean their bikes?

I've run into a similar issue -- a rider who was going up a hill and shifted, dropping the chain and wedging it down in the bottom bracket. It was really stuck.
I stopped to offer help/support and he was pretty agro.

Having seen this type of thing before (DAMHIK), I tried to explain that the most effective thing is to remove the rear wheel (putting slack in the chain) and attempt to remove the chain by working with the chain under the bottom bracket, pulling it down and forward then up. Like many of us, he kinda wanted to 'do it his way', so I just shut up and helped him steady the bike while went about the task backward -- and unsuccessfully. He was getting angrier by the minute and wasn't in the right frame of mind to listen to suggestions.
He finally gave up and decided to call someone else.

No problem. If someone wants 'help', it's not my job to give him what I think he 'needs' if it's not what he wants.

BTDT.

Meanwhile, back to the OP's question:
<<im sure mine was from cross chaining>>

"Doc, it hurts when I do this."
Well... don't do that.

Too many riders don't know a thing about "transition cogs". These are cogs best used to achieve good crisp shifts. I avoid the 2 or 3 smallest and/or largest while shifting the front rings. I have a double crank and a triple. The triple shifts just as sweet if you pay just a little attention to what you're doing. Most don't though. Too busy trying to beat Lance in a TT while riding the trail!

It's the same thing with flat tires too. Too many riders think they know what they are doing but don't. They pinch the tube then flat 2 minutes after a roadside repair then blame it on a bad batch of tubes.

Reminds me of two cliches:

"People get what they deserve." - that'd be the LaGrange guy...

"No good deed goes unpunished." - That'd be Bob.

I stopped offering help to riders with flats who obviously had no intention to even begin to fix the thing themselves.

No saddle bag, no pump, no spares?

Sorry, you're on your own. I just won't cooperate with people's self-defeating behavior any more.

I'll second that. I was cutting through the Rose Bowl a while back when I was approached by 4 guys that wanted to borrow a multi tool so one of them could make a seat height adjustment. What; out of four people, not one of them had some sort of multi tool??

Hey Man, multi tools add weight. I have a friend who carries only one tire lever. There is an old saying. " If you want a lighter bike, loose some weight"
