Thank you for all your comments.
I suppose that if exposure to sunlight / daylight has a detrimental effect on carbon frames, then the same concern should be shown to other components [handlebars etc.] which don't usually have a "protective" paint finish, as most bicycle frames do ? The failure of any of these components could be very dangerous indeed.
I wonder if the car and motorcycle companies producing carbon bodies / chassis etc. have any structural concerns reference sunlight / daylight !
Does the number following XTR8R on the Cinelli frame have any reference to the year of manufacture or frame size etc. please ?
