Bigger 24 cm + circumference plastic bottles kind of just get munged and deformed.
I noted a review on Amazon of the Polar Bottle griping about its narrow waist, I think because it prevented putting more ice in, though I took this to be a possible benefit as you say. I'm guessing the waist is helpful for fit of the Polar into the Iris, but bet the smaller outside circumference of ~ 23 cm (or 74 mm diameter as you measured) is as important.
Well I'd imagine if King Cage says the Kleen Kanteen fits, they've probably tested it. Should be good to go.
I was thinking that someone should come up with a new version of the old REG spring clip cages, for people that like rigid metal water bottles. That's really what they were designed and optimized for. If it worked with aluminum bottles, it should work with modern stainless bottles too. The bent wire cages came out after plastic water bottles took over, as far as I can tell.
AFA the Polar bottle waist being a problem, I didn't realize that anyone put that much ice in. Easily solved by using smaller ice cubes... I might plop a few cubes in on a really hot day, but it's going to be warm at the end of the ride anyway. Since I have dual cages, I will sometimes freeze the second bottle. For me, warm water is fine and doesn't bug me, as long as I have water. I guess I'm used to it because that used to be the only choice BITD.
