Can I sandwich-mount a sprocket to these rims? (44- tooth) I know that these aren't exactly what you wanna be using for this kind of mount, but I'm too cheap to buy a disc-mounted one. It would be a shame to waste the beautiful freebies... LOL I love the garbage in a college town. Image Hosting Myspace Image Hosting Myspace Any possible way? At all??? If not, does somebody know the absolute cheapest place to buy a disc brake mounted sprocket? Can I drill my stock one coming in the mail to fit a disc mount?
