How to remove printing on aluminum stems and bars

I'm building up a bike and am using some parts from a Cannondale, specifically stem and bars. The stem and bars are black aluminum matte finish (like this: http://goo.gl/Sr6mN) and the word "Cannondale" and the Cannondale logo are on each in white.

Is there a way to remove the white lettering and leave just the black matte finish?

Depends upon what was used to apply the black matte finish and white lettering.

If it's decals on top of the black handlebar & stem, heating them up with a hairdryer will let you peel them off.

If it's black-anodizing on the aluminium and white paint, then paint-stripper will remove the white paint and leave the black alone. However if both black & white are paint, no easy way to remove the white without damaging the black. Personally, I would just sand both stem & bars and spray black over both.

Quick and simpler way would be to overwrite the white with a Sharpie marker. May not be a clean as re-painting, but certainly easier and quicker.

Not sure how the black is on there, but the white is definitely a paint or paint-like over top of the black. Can try paint stripper, but don't want to affect the black or leave a section of of dulled-out black.

I've used Sharpie before, but it tends to not fully black out the lettering and also eventually it wears off.

Just take some laquer thinner & wipe over it. I've done this with parts in the past. The white comes right off.

Can't you look under the clamp to see if you're dealing with paint or anodising?
