^^^ Nice write-up, pcb .

FWIW, the Compass and Grand Bois tires I’m using (700x28, 32; 650x38) measure true to width or maybe a mm bigger on 23mm (outside width) tb14’s and Pacenti Brevets, except for your correct assertion about those GB Cypres 700x”30”mm. I’m just about to replace my last of those after almost 4000 miles on the rear (following 3500 in front). The replacement Compass (haven’t bought any as RH yet) Stampede Pass 700x32 EL should be a little bit better fit under the Marinoni’s fender boss under the rear brake bridge.
