    rear derailer hanger bolt for 2012 specialized rockhopper comp29

    Hi I snapped the bolt that holds the rear derailer hanger on my bike and I'm having trouble finding another,can I use a normal bolt from the hardware store?

    This stock bolt is hollow,and alluminum,and it snapped when I simply went to snug it down,is this common? And are you supposed to gently snug these bolts?

    Now would be a good time to buy a spare hanger, (they come with a bolt), for the next time you have an issue. The hanger and bolt are considered to be expendable, like a fuse, to protect your frame from breaking.

    Almost looks like a chainring bolt. They are available in aluminum. Check with your LBS.
