Re: New Zipp 858 NSW and 808 [Slowman]
Here is why I get confused

if I take this chart



Just focusing on the "old wheel" (red line).

Would you agree the fact that there is no CRR difference between 60 and 100 PSI is strange ?

Do you not believe there are road surfaces where 110 PSI will be substantially better than 60 PSI with a 25mm tire ?

I would expect this (from this ST article)




And if so, if there is a .001 difference, that is close to 8watts better at 36km/h, bigger than the savings in the top chart.

Where does my logic break down ?
