^^Have you considered including drivetrain mechanics i.e. a high/high vs. low/low chainring/cog ratio?
For instance a 40/13 gear ratio is virtually identical to a 52/17 ratio, but provides an entirely different riding experience; thus low/low enabling much quicker acceleration/deceleration, while 52/17 will give you greater momentum at top speed...
52/17 is 0.5 GI lower so it'd have to be one hell of an inexplicable difference to be actually noticeable. The only other variables are weight, chain tension and the angle of rotation of the chain links - and all of these are negligible. Am I missing something (other than it being a placebo)?
