It was really cold and I was on my way to work when I shifted to my lowest chain ring. The chain came off and got wedged in between the chain rings and the chain stay. I tugged a little and it wouldn't budge. I tried manually back pedaling, but it didn't come undone. After a minute of gentle experiments, I was getting really cold, so I just yanked the chain out. It took a little muscle. It also ripped off quite a nice chunk of paint. I can see bare metal.

So I'm worried about the frame exposure. It's gonna get a lot of muck and road salt in it. Is there danger here? Might the frame be weakened if I don't take action? What should I do?

It's steel, so I will try that.

While your at it, check your front derailler low limit adjustment to avoid a repeat performance.

I will do that. I've been riding this bike about 60 miles a week for a few months and this is the first time something like this has happened.

Well since its steel i wouldnt worry, that happened ot me a while back. I make it a habit to check the front der. and make sure it only allows the chain to move to the right point, seems to help

It is, and it does. :)

You can buy an anti-chain suck thing for the bike, too. I put one on my Attitude after getting it *real* bad once. I don't think that you would necessarily have to do that if you're riding on the road.
