The Surly rack won't work as you need low rider mounts as well as the dropout eyelets
Similar question asked about a week ago, some of the answers are dependant on if the suspension fork has rim brake mounts, and how much weight you want to carry on it, don't expect it to be too cheap if you want to carry a lot of weight on the front (20kg).
