A thief attempted to lever off my D-lock with a seat post. In the process they managed to bend the seat tube on the aluminium frame. I don't see any cracks on visual inspection but it doesn't really make me feel a whole lot safer about riding it now. I do intend to replace the frame eventually but I don't have time to strip down the components right now. Does anyone know if aluminium bent like this is still structurally safe to ride?
