This photo is of a team mate who had his 2nd ride on his brand new S works frame brought locally (QLD Australia)

The driveside side seat and chain stay snapped in 1/2

The frame is now at the LBS

Thankfully the rider is very experienced and managed to stay upright otherwise it would have been a disaster.

The logo you can see on his jersey is one of our sponsors "DWBH" = dont worry be happy..... :D

Might have been a defective glue job. I am glad the rider had the handling skills to avoid a crash.

Nice job on the photo too.

Might be time to ask for a Venge like the other gentleman.

The rider is a very good Masters A rider and the photo was taken at an event held over the weekend in Brisbane.

Crazy save. That rear wheel isn't even really held by anything :O

Brilliant photo - at last some proof that he was "just riding along" (sprinting up a hill, which happened to be perfectly smooth).

Hang that one on the wall.

Clearly a manf error to have failed that early. If we ever get to find out the cause I'd put my money on bonding of the chainstay.

Glad the rider had the skills to save it.

From the pic I can't see where it snap. Can you get a better pic.

It snapped 1/2 up the sweat stay and 1/2 along the chain stay
I will get photos of the frame.

Why did the quick release let go on the non drive side?, even if the frame snapped the two drop outs should have been more then enough to hold things together... I it just me or could this have been a result of a broken or too lose QR?

I wondered the same thing- but just as likely is that the rear wheel wrenching around might have caused the threads of the skewer to snap as well.

A loose skewer is more likely to pull the wheel out of the drop outs, not cause the stays to snap.

Everything can fail. even our most beloved tools for the sport. I think it is smarter to first finish the warranty claim and then start showing pictures.

I don't see how it matters where the warranty claim is up to.
That is a fantastically timed photo though, thanks for sharing.

...loose skewer led wheel to shift, than chain was sucked between chainstay and chainring when rider torqued on pedals (perhaps made worse if rider was also shifting under load), then chain simply severed the chainstay. My assessment is based on what appears to be an intact NDS dropout and a chain that is not visibly on the chainrings. It just seems that this sort of catastrophic failure is HIGHLY unlikely. Actual pics of damage will help solve this "mystery." EM3
