Sounds totally reasonable to meDamn ya that's all bent up! I agree the aluminum or whatever metal they use is just not hard enough especially for the part that takes the most torque being attached to the spur and essentially the motor. I get keeping weight down but I don't think it would cause a huge issue being say steel and a bit heavier and stronger. I mean there's no issue changing from the really light plastic spur to steel spur so don't see heavier slipper hubs causing a big issue either.
And if a person orders the whole assembly with the steel spur is the other metals all still what they would be otherwiseSounds totally reasonable to me
