Is there any way, x ray frames for trace of fatigue, etc? that could be done?
Short answer is no.
Longer answer is maybe yes. Surface X-ray reflection can be used to measure residual stress, so if a metal is fatigued to the point that it is about to start failing and is graining up, technically you should be able to see it. However, this is a very specialised technique and I don’t think it’s commercially used yet because it’s very much in its infancy. Also, if it’s got that far that it’s graining up at the surface, I’d wager you’d be able to see it visually first and you’d already have felt the bike getting a bit noodly at the front. XCT would also not be able to give you any indication how long you’ve got left, only if it’s right near failure.
Apols for the nerdy answer! I’m a materials scientist and done quite a lot of work on surface stresses in metals.

Except there's always noises, chainring bolts, saddle rails, etc... Riding with peace of mind becomes impossible, that was the spirit of my original question... Is there any way, x ray frames for trace of fatigue, etc? that could be done?
