Cool. The page you linked to was confusing, first saying 56 miles of pavement in the text and showing a mostly paved route on the Komoot route profile (including “lastricato,” which I thought was equivalent to cobblestone, but I didn’t know that kind of road existed in California!) and the switching it around to 56 miles gravel in the route summary section. I looked at RWGPS, too, and thought it was 56 miles paved roads, but maybe I looked at the wrong year, wrong ride, or just simply misread.
Anyway, I was thinking that in a situation where you might get up in a fast gruppetto, 700c might feel more natural, but I guess since the route isn’t gnarly whatever the surface mix, choosing to go the comfort route with wider 650b isn’t a bad way to call it.
