I dont think the white is a bad idea, just the fact that the white grips will turn black, the seat will get nasty real quick, and the cylinders are also usually a dirty spot. Its up to you, but i think the white will look good, i think if your going to add the white to the scheme then we mines well jsut get rid of the black all together like fast fibers bike up there. But like others have said black and pink looks good (for a girls bike lol just messin).
