Not sure how it happened, but I believe I bent my chainring, when i'm pedaling the chain will be taught for 3/4 of the rotation till it gets to a certain spot where it will lose its tension and sometimes click. I don't really know too much about the specifics of bikes, still just in the learning stages. I'm wondering what would be a good replacement for this as I need to call and order from a local shop, but don't want to sound like an idiot trying to explain.
