    bent middle ring tooth...

    On my Giant, one of the teeth on my middle chain ring is bent inwards. The chain rides over top of it. I can only assume that I caught a rock or something.

    Should I try straitening or is it a good idea to get a new crank? I'm going to be buying a new frame, so a cheep crank/bottom bracket combo would work best.

    Is the ring steel or aluminum? You have a better chance of bending it back if it's steel.

    I'd try unbending it - at worst you'd have to get a new ring anyway.

    I honestly don't know, but I believe its steel. Crank sets aren't cheap

    All you need is a ring, not a crank set.

    I don't think the rings come off separately. Even if, I'm not the biggest fan of this crank set, just didn't think I'd have to spend on it now. (was planning on getting a new one when I got my tires for ice-riding this winter.

    Go ahead and...

    try straightening it. If it's a lower end crank set without individually removeable/replaceable rings it is almost certainly a steel ring. It's unlikely that you'll end up any worse off than you are now. Just do it carefully and slowly. Best tool to use if you have the room is a small adjustable cresent wrench or something similar with flat smooth jaws.

    Yep, bend it. If needed, take a chain saw file to any rough edges.

    You have 32 teeth, about half are grabbing, an ugly or missing tooth won't matter as long as it's not harming the chain.

    I bent it back. Entire thing is steel (blech). Also turns out that my bottom bracket is worn a bit. There's a bit of plan in the crank. I hate this part of mountain biking.
