When it comes to weight difference though, a lot of it has to do with the amount of difference, and what is a detectable difference for example take 2 riders, both are 100kg, in fact they are identical twins who have the same athletic ability the same genetics, the same amount of experience, one has a bike that is 9.80kg and the other has a bike that is 9.79kg total for one is 109.9 the other is 109.79 a difference of 10g the bikes are identical except for the carbon bars, one has bars that are 10g lighter. I think that would be statistically insignificant.
