bar tape should be like bike shorts--black, as it gives you something to wipe your hands on that doesn't show dirty. White bar tape will be dirty very quickly, and yes, it can be really easy to clean, but often it gets left to do 'later'... and you don't realize it is dirty until your next ride, and then it just gets dirtier. I don't wear white shorts for the same reason... one flat, and I absentmindedly wipe my hands on my legs (as if I were wearing jeans)....and if the shorts are white, you have stains that last forever. Go for the black
