    Typical derailleur hanger, but with a design flaw

    Posted by Jim D on 10th Aug 2015

    There is a stress riser at a point where the contour of the hanger transitions to the frame. This sharp edge is a perfect place for a Crack to form. This is what happened to my first hanger. I added a small fillet to this area to remove the stress concentration. Otherwise, it does what it is supposed to do.
