Read people say they've mounted them on Flow EX (29.1 ext 25 .5 int), not sure I'd go to 23. Experiments with them on Blunt/P35 led me to decide the profile was "ok but not perfect" compared to seeing them on a 45-50mm rim.
Yeah, sort of mushroom shape if you did a cross section, you have to run higher pressures too avoid squirm in the corners, defeating the purpose of going higher volume.
I assume a 2.2/2.3 would work on the 23mm rims. I ran fairly skinny 2.3s on 19mm and am still alive.
