Is Less Weight Better Than Aero? Giant Propel vs Factor O2 VAM timed comparison

What's more important when cycling, weight is aero? To find out I've put a lightweight and an aero bike through a comparison test to discover the answer. This video features the brand new Factor O2 VAM weighing 6.3kg and the mid-range Giant Propel Advanced coming in at 7.8kg, but can more aero overcome the weight penalty?
