The Runwell MEX is a ball ended hex wrench with an 11cm long ruler etched into one side of it. I love this idea. I know some of us can be sticklers for certain things like saddle height, quill stem height, or even centering handlebars. These MEX wrenches make it so you only need one tool for the job.
The ruler measures from the end of the wrench.
