True, true...but were talking extremely insignificant here. Your chaingring has way less diameter than your wheels and is spinning 2-3 times slower. Wheel mass is WAY more significant. Hell, the weight of your pedals and shoes and crank arm length would even be way more relevant to acceleration than the diameter of your chainring.
