I often see it stated as established that drum roller tests are reliable approximation of real world results on real world surfaces, but I’ve yet to see where this is actually demonstrated.
And I will say up front that the results the Rolling Resistance guy gets for the Bon Jon Pass tires is a big red flag for me for that methodology.. Another test by Tour (a german mag) had them coming in as one of the fastest they tested on rougher surfaces.
And just riding them, I know first hand they are ridiculously fast rolling.
