Review on Park Tool DCW 3 Double Wrench by Dee Fadaifar

This is an essential tool for changing and adjusting wheel bearings on regular bikes. Most bikes use 15mm, sometimes the front wheel is 13mm. This tool is very thin, around 1mm, so you can usually adjust the cones on your bike by loosening just one axle nut. But never use it for anything other than tenons, or you could splay your jaws. Like all park tools, if used properly, it will last a lifetime. Park also makes a pedal wrench that is thicker, maybe 2 or 2.5mm, but thin enough to work with most cones. However, I think it's only the 15mm size.
