Roads? We Dont Need Roads!!!!
Yeah, better build quality. You can also take it apart to clean it/service it yourself - can change springs in for different PSI should you remap I think. Better noise in my opinion but not loud like a dump valve that you spoke about before. Makes gear changes better for some unknown reason to me.
