I wrecked my RydeANDRA40, probably by using too much pressure on cobblestone and pothole ridden roads.

Fatigued metal is weaker than it was before.

Fun fact: aluminum has a limited number of stress cycles it can go through before breaking due to metal fatigue. Unlike steel -- which will bear its designed load an infinite amount of times if you never exceed its strength -- aluminum's failure is eventually inevitable. Even very light loads can break aluminum after enough repeated cycles.

For a part that goes through a stress cycle every single time your wheel turns around, I wonder if that could have actually been a factor here. You're putting it through thousands of stress cycles every time you go for even a short ride.
