My LBS guy got my rear wheel bent back as best he could and said it will do for now but that I'm definitely going to be needing a new one. He said it will be hard to find a match for the one I have (Bontrager something (SSR? SSX? 55R? 55X? it's hard to read). He told me to research it and let him know what I want to order.

How do I know what kind of wheel I want? I have no clue.
