E-Thirteen Finally Answers the Age-Old Question:
The two wheels have different aerodynamics. If the metal inserts in the first wheel are positioned roughly at half the radius of those in the second wheel, then their velocity (for the same axle velocity) is half of those in the second wheel. Thus their resistance to the "wind" is much lower (wind resistance is proportional to velocity^2). Thus, strictly on aerodynamics the first wheel should travel faster as shown in the video. A more appropriate/fair test would be where the thickness of the plastic part of the wheels is the same as that of the metal inserts.
