cracked carbon frame warranty question

My rear mech hanger snapped and appears to have cracked the chainstay too. Obviously the mech hanger has done its job but will the crack to the stay be a warranty matter ? The frame is 6 months old. Any helful answers are appreciated. Thanks.

in what way? its job is to protect the frame

You’re right it hasn’t done its job in protecting the frame in that respect but it snapped without a catastrophic frame failure,so could it be argued it has done it’s job or should it be considered for a warranty replacement ?

Cracked the chainstay or merely caused a witness crack in the paint?

But it has caused a catastrophic frame failure, it’s broken the stay…?

What’s the frame, have you got a picture of the damage?

1st call is to whoever you bought the bike from, once you have done that then you can speculate until they tell you. If I thought my frame was cracked I would be straight back to where I got it from.

Ok so apparently the damage isn’t covered by the warranty because it was caused by the hanger ? Can somebody clarify for me what the mech hanger is meant to do, is it to protect the frame from damage ? If so then surely if the chainstay cracks after the mech hanger fails then it hasn’t protected the frame and should be covered by warranty ?

Nearly all warranties are

‘a warranty against defects in materials and workmanship’

and have a list of exclusions

Normal wear and tear
Improper assembly
Improper follow-up maintenance
Installation of components, parts, or accessories not originally intended for or compatible with the bicycle as sold
Damage or failure due to accident, misuse, abuse, or neglect
Labour charges for part replacement or changeover

I suspect you’ll be looking at subsidised frame replacement (at the discretion of the manufacturer).
