So it would be feasible that the frame doesn't shrimk in the cold, but the bonding epoxy does and becomes more brittle.now put this with a high stress area like bb or seat post amd it is perfectly feasible that over time the bond will weaken and the insert come loose...ok?
So why didn't all the frames fail spectacularly during last year's Milan-San Remo? Or any other race where temperatures are sub zero?
Why have none of my carbon frames (Cervelo, Scott and Giant) failed when I've used them in temperatures down to -10°c? Why haven't they failed when I've stored them indoors at room temperature and then taken them outside and ridden them at below zero?
Why haven't they failed when I've flown them over to Majorca in the freezing hold of a plane, and then jumped on them and ridden them, when the frame is still cold to the touch, in 30° heat?
So many question marks, so little time...
