Clement LGG 28c mounted on I9 ULCX wheels (21mm inner width) = 29.05mm wide at 90psi. Easily cleared my Enve Road Disc fork. The wider rim doesn't really make the tire taller, just wider.
Also, tire weighed 236g for the bean counters. I only weighed one of the two.
Haven't ridden them yet, so no real world thoughts on it.
Mounted a pair of 28mm Ones last night in a tubeless setup on SL23 rims. With zero miles they measure a hair over 29mm.
I just picked up a really nice Eriksen that the owner fitted with Compass Chinook Pass, 28's. My first experience with these and I'm very impressed. They seem to just roll and roll, and unbelievably comfortable as well as confidence inspiring, great cornering. Disclaimer, for the past decade or so of my life I've ridden GP3000's, now the 4000's, 23's and 25's.
The Chinooks are remarkably light for the size and so far seem to be wearing well. I'll measure later with a caliper and post the exact width. I've got mid reach brakes and could probably easily get away with 32's. But so far, these Compass tires are impressing me.
