In the past few years I have had a couple rear wheel failures. I am wondering how common these are, and also since these are aluminum rims, what options exist to hack/bodge a repair with some type of epoxy or even a few drops of molten metal.
My best guesses are these are reasonably common and no way to repair the rims.
The failure is the rim cracks at the spoke/nipple insertion spot. See pic below.
Oh, I am light at 140-145 pounds and would estimate these wheels failed at roughly 10-15k miles. Interestingly I have only ever had one front wheel ruined and that was a hard rock that hit/split the edge of a CF rim.
All comments appreciated.
