Yeah, I've worked out the numbers here in this forum a few times. The difference between a super stiff frame and a "noodly" frame (using measured frame stiffness) was less than 0.05% of Power. Or something like that. I can't be bothered to run the numbers again or look it up. So maybe 0.2 Watts at a big effort of 400 Watts.Crankyfeet said:You don't need to do an experiment. It's simple physics. Doesn't SOMEONE around here have some knowledge of physics/mechanics....
It is the same reason why a guy gets a better start in a 100 meter sprint by pushing off rigid starting blocks as opposed to the same guy pushing off foam rubber blocks. Any deformation of the frame is work absorbed that is not being transmitted via the chain to the rear wheel.
In other words, the zipper on your jersey will probably have a bigger effect...
