Most aluminum or composite frames have replaceable derailer hangers that bolt on to the right rear dropout. These are designed to be a breakaway/replaceable part so that serious frame damage will be avoided in the event the rear derailer goes into the spokes.
There are quite a few different variations on these from different manufacturers. We stock some of these, but since there is now over one hundred different hangers, we've made them available through our special order catalog.
Some of these may fit other frames as well as the ones listed. If your bike is not listed, but the drawing matches, there's a decent chance that the hanger shown will work, but we can offer no assurance of this, and these parts are not returnable.
We offer these mainly as a service, this is not a major profit center for us. If we have to do a lot of hand-holding or accept returns, it becomes a liability...that's why most shops don't like to deal with these.
