Black bikes have an understated stealth look, unless the manufacturer plasters them with decals, which is the case with many carbon bikes. I've had two black bikes and really liked the look for commuting, but unfortunately both bikes (both Gunnars, coincidentally) did not fit me very well and I sold them. I particularly like the combination of black and tan components, as in my Gunnar Sport. The red-and-black Crosshairs was a homage to my alma mater, the Georgia Bulldogs.
