The CONI text that was quoted in the other thread is, in "fact," an assertion. I'm not dismissing the CONI assertion but merely identifying it as such. One reason I don't dismiss it is that it sounds pretty sensible that wider bars might allow more breathing and I assumed they were right about that until I tried it myself, and at least for me it is not the case--perhaps for the reasons you mention. You refer to research CONI, and presumably others, performed that proved that wider bars allow you to breat better and I assume you are right that such reaserch was performed even though the quoted CONI text doesn't refer to it. I remember, too, reading about various research about this in the 80s. I'd be careful of using the word "fact" to refer to the results of testing and research though. Research evolves. One can say, however, that it is a "fact" that CONI's research resulted in the conclusion that wider bars allowed better breathing.
