I'm installing the rear derailleur from the silver bike to blue bike but obviously I didn't notice this little problem; the blue bike doesn't have that hole I need(the one I'm pointing at).

After looking around, I found this:

Just posting to make sure, it'd work if I used this adapter on the blue bike, right?

Close, but no cigar for you. That's a replaceable hanger for a specific frame. Actually, what you need is a claw shaped adapter usually supplied as part of a cheap derailler these days. The claw bolts to the back of the dropout using a specailly shaped nut that fits in the dropout track.

If you ask at you friendly LBS, they should know exactly what you need and probably have one sitting around. I don't see one in the QBP catalog so I don't know if can be ordered.

EDIT: Found one at loose screws: http://www.loosescrews.com/index.cgi?c=Derailleur&sc=Rear%20Hanger&id=982585320835 but they're on vacation until the end of the month.

hmm, yeah I know it said it's a replacement but I thought that smaller screw can be attached to the one provided on the frame.

I'll try asking my LBS for any parts
