Where are you located? What size is the frame?
I think your best bet is to use it for training/weekend rides if it fits you and get a cheap rigid MTB for commuting or sell it and get something with eyelets that fits. It gets to be a pain when you "rig" everything and then realize finally that it just doesn't do what you wanted because you started on the wrong platform.
That's why I'm selling off all the other stuff I've got and finally have the "right bikes" on the way.
