If you can find an old "Cool Tool," grab one. It is indeed a nifty gadget. Includes an adjustable wrench that has flat jaws, which also can serve as a cone wrench and even turn the included crank bolt socket. I don't think they make them anymore (correct me if I'm wrong), but I love mine. See http://www.mtbr.com/cat/accessories/...74_152crx.aspx
