They use the crazy wide hubs b/c most of these frames have crazy wide rear spacing, b/c you'll need wider chainline to clear the crazy wide rims/tires. If you want some more specific troubleshooting, tell us all the details about your current rear hub or, better yet, take a picture or 2. You might be able to despace it.... but yeah, you can run a regular hub; you just need to find other means to move the chainline out far enough to clear the tires....
While youre at it, you might want to talk about your crank plans and all that, too...
