Well, you hit on one of my peeves here. As others have said, it’s cheaper to paint or anodize black than to polish. And it’s a lowest common denominator thing. BORING!

I’ve made compromises in other spheres (getting previous generation hi-fi speakers to get blonde wood, previous generation flat screen TV to get white), but I mostly refuse to stoop to black components on my favorite bikes...

Black is not a designer color. It’s just lazy.
