I was out riding, and I'd stopped for a moment to take a drink of water out of my bag when I accidentally dropped my bike from under me. When I got home, I noticed the right brake caliper (I have the Shimano ultegra) is bent! So, is there a way to straighten it up without messing up my bike? Is this going to be something that's going to decrease the quality of my ride if I leave it as is? I'm not sure what to do. I just don't like looking at one brake bent and the other brake is fine!
