I view components as just another building block in the system that is your chassis, and that system should equal a certain level of compliance. That level of compliance will change even significantly from rider to rider, and less-significantly, but still present from course to course.
I prefer to have more stiffness and damping in my bars, stem, wheels and frame, and less stiffness and damping in the tires, and suspension. It fits my more active riding technique and higher level of body english.
Strangely, I don’t prefer most carbon bars to aluminum, but ENVE feels markedly different to me. I find most carbon bars flex too much and have a snappier, kind of bouncy characteristic to them. It inserts a level of flex and unpredictably where I don’t want it. ENVE has a much more solid feel than most, IMO.
Although, if I were to switch to a different bike, or change suspension, or wheels, I might need a different bar to get the overall compliance I would want.
