I just had this same problem. Didn't even realize I had a bent wheel until I was cleaning it after the ride.

Shop owner straightened it for $15, but said to keep an eye on it and said it won't last long. Then proceeded to tell me he'd give me a good price on a replacement. Is a slightly bent wheel garbage, or should a repair hold for a a while?
