Hey, they're carbon, to satisfy the weight weenie in us all :-)
I think your Roadeo would look better with silver parts though , unless you get it repainted something colorful to go with black parts !
I have to say though I bought some Lezyne Power cages and love them better than the inverted stainless type. They're made of hollow aluminum,kinda chunky looking , but cool, and painted to boot, so no bottle marring.
I bought a set of black Mavic Aksium130mm wheels for my VO Rando frame. I may have the frame painted something else, I'm not sure yet. The black wheels will go with the the "Trout" metallic gold based green paint, but my heart screams for a bright sparkly metallic orange. I have another custom frame about to be built that I'll have painted in sparkly orange PPG Pearl paint ! I do have some BBB cork ribbon bar tape though, in bright orange, ready to put on something !
