Winter Larry asked about the bars on one of my bikes. On that bike, the Yellow Maserati, I have the Velo-Orange Gran Cru Course.
They're similar. The Velo-Orange has an expanded section in the tube where it goes into the stem; the Nitto uses a tube-within-a-tube system. The Velo-Orange may have a bit more flare in the drops. The Velo-Orange is polished in the section between the tapes; the Nitto is bead-blasted, but both have brand markings.
I go for raw metal rather than black. My stems (also from Velo-Orange) are polished, as well.
