For those who've done the 27 to 700c conversion: If you're running fenders and tires labeled 35mm, what's the measured width of your tire? I'm getting slight rubbing between the front tire and fender with a 35mm Gravelking SS, which runs true to size.
Apparently, I also need to go back to the drawing board for cantilevers to make the conversion work as the Dia-Compe NGC 982 doesn't do the job. (More info
