Do I have a bent fork?
 

I have a road bike that, when I ride it, pulls slightly to the right. What could this problem be and how do I fix it? I think my fork might be bent and that is what is causing it, but I am not sure.

Thanks,

could be bent stays too. check wheel your wheel alignment in the dropouts.

Could even be your gear or brake cables pulling the handlebars to one side

You could certainly check the alignment of your fork, but the first thing that I would check would be the dish of the rear wheel. That's commonly off by several millimeters in factory built wheels and that will cause your bike to drift to one side when you ride.
