Proof that bicycle components are lamentably fragile, that's what.
And I was nearly stopped, too, with one foot down and turning to get out of going down an unhelpful bit of bike path in a park. Not a high stress situation.

Ride 48km and what do you get?

Huh, that's wild. Did you buy it at a local bike shop? I hope you can get $$ back for that.
I did buy it locally, they're great guys, and I'll be taking it in tomorrow whole and entire, possibly so the guy who does ordering can beat the SRAM rep with it. (I should remember the Kona gloves while I'm at it.)
Not the first chain ring I've bent, either, though the first one from a "good" grade of part.
I've never even IMAGINED bending a chain ring in use. But I'm wimpy and smallish and not very powerful on the pedals.
I'm quite sure it was a manufacturing failure; about a fifth of the chain ring -- which is supposed to be hardened -- had a ductile failure, which is really inconsistent with having actually been hardened. Especially since the actual load was low when it went. (I'm kinda pleased about that; having it go while trying to bounce a rail underpass and doing ~45 kph in the near-dark would have been *much* worse.)
I won't say I'm not thinking about Ti chainrings now, because this whole thing makes me anxious, or that I haven't bent chainrings (or crank arms) before, but those were much lower on the food chain and not meant to deal with someone heavy. (the Apex chainrings, one step down, worked fine through ~1400 km and are not even showing any particular wear.) So I'm pretty sure it's just that this one slipped the QC.
