See the attached picture for more information. But basically I'm shopping for a cheap BB tool that would allow me to undo my bottom bracket. It seems there are two options, one is a wrench type tool and another would be a socket type; there are many different standards for bottom brackets, so I have no idea which route to go. I also have no idea what model my bb is; all I know it's from a K2 2006 Zed 3.0. Ideally I would like to get a tool compatible with many bottom brackets.
