My cracked Spec Roubaix bike frame - the resolution

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Either it happened when he was not on the bike, or there is much more to the story.
it could have easily happened without the OP noticing. ( see the missing Cervelo seat stay above.)

Iíve hit tons of sticks and never thought anything of them. OP could have easily hit some debris, thought nothing of it, and not noticed the crack for sometime. You could ride that bike for a long time in the condition pictured without feeling anything wrong.

Good for them; glad to hear that.

However...a company that had to honor their warranty 3 times would make me question their quality control.

Gee, thanks.

I think I'd have noticed if I hit a branch hard enough to break a carbon fiber frame. I'd guess that would have taken out a few spokes, too, but apparently not.

But, as I'm learning in this thread, so many Internet experts who weren't there and haven't seen the bike (or seen me, or talked to the LBS managers) have better knowledge of what must have happened.

Uh, you *were* there and you still don't know how it happened, so what does that tell us?

But yeah, when given the choice between a) spontaneous failure in *that* mode and in *that* location vs b) a rider that hit something and didn't think anything of it... yeah, Occam's hitting the "Easy" button on that one.

You donít believe the experts at Specialized, either - and they built the bike.

I know the chain (the largest in DFW right?) and they are a good business. Good that they kept on it.

You see certain things often enough you don't need to see the bike in person nor talk to a random bike shop manager, I don't care how 'experienced' he is.

Just riding around isn't going to stress that area enough to cause that kind of damage. An impact, like from a branch swept in to the wheel, is more likely to cause the type of damage seen on your 'stays. Knowing this explains why Spec "dragged their feet."
For gods sake delete that photo demonstrating that one of the seat stays is just there to make the UCI happy, before the weight weenies see it and break out their hacksaws.

The rider most likely noticed he crashed. When eventually he discovered the missing seat stay, I doubt there was any ambiguity in his mind regarding what had happened, and when.

The truth is none of us, including the OP, know what happened in this case. We can make guesses, like the family dog jumped on the bike while it was on its side in the SUV. But it is pure speculation.

The main point is that Specialized (for all their sins) reasonably assumed that the stay didn't simply crack while just riding along. It may have, but if so, it is clearly a total fluke.

The main takeaway here is that lightweight carbon frames do have some pretty delicate parts (especially pencil-thin compliant seat-stays) and you have to be ultra-careful about transportation, storage etc and you have to be extremely careful when using bike carriers. For example there was a picture of a pro racer's bike that "spontaneously" snapped halfway down the seat-tube while JRA. After several pages of speculation, someone simply posted a picture of their team car with half a dozen of those bikes on the roof. Guess were they were clamped to the bike carrier?
