That's a problem with aluminium - no fatigue limit. This means that cyclic loads on an aluminium frame (or pole) will eventually cause it to fail. Steel does have a fatigue limit such that cyclic loads below that threshold won't cause eventual failure.
There's some good info on bike frame materials here: https://bike.bikegremlin.com/11144/bicycle-frame-materials-explained/ https://bike.bikegremlin.com/11144/bicycle-frame-materials-e...

- prmoustache 2y agoIt is only really an issue with aluminium forks and non traditionnal construction. With a "diamond shaped" traditionnal cycling frame you have nearly 0 chance of a frame failing catastrophically. Usually the weaker part crack and your bike just end up creaking horribly and/or feel noodly. I have suffered and witnessed a number of alu and alu+carbon bonded frame failing at the glued joints.
