But what if you translate Crr to climbing?
Robert Chung - Nice explanation for why Crr scales exactly like hill slope, so a Crr of .005 creates exactly as much drag as climbing up a hill with slope of 0.005 (i.e., half of one percent). If you’re comparing a tire with a Crr of .004 against a tire with Crr of .005 (for a particular surface) the second tire would be like climbing a hill that’s .001 (= 0.1%) steeper. That may not seem like a lot, but over a 200 km race that’s the equivalent of climbing an extra 200 meters compared to the lower Crr tire.
So by my probably incorrect calculations based on https://www.bicyclerollingresistance.com
compared to GP5000 (tubes) over a 4000km ride:Pro 4 Endurance V2 = 5040m extra climbing
Gatorskins = 11840m extra climbingThat is based on the Crr difference of one tyre, no idea if it doubles for two.

I nursed my tyres through most stuff without issue in the past but the added stress of doing it means I'm of the opinion sod Crr just gimme thicker rubber. I'd rather just blast through stuff than finesse every rough section.
