Should I push for a warranty replacement of my rim?

Harder to answer. Poor design, DS bearing placement/support, weak material/material defect, rider weight, bumpy roads, a big hit, all of the above?

Much more common on old non-cassette hubs where the DS axle would hang WAY over the DS bearing, but it can still happen.

Wish you had been my mechanic instead of the guy who made me feel like an idiot for coming back multiple times and forcing me to buy a 23 mm tire, in spite of the fact that 25 mm worked fine before. So what would cause an axle to break without any other substantial damage to the wheel?
