I was riding in the woods the other day and I caught my front wheel in a root. now my Manitu skareb fork is totally broken and my wheel needs to be replaced. I was thinking that I do not really do much off road biking anymore and I prob. do not need a suspension fork. I have a Gary Fisher Big sur and I am wondering what I have to look for when buying rigid forks to replace a suspension fork. does any fork fit on the bike?

thanks,
Brian
