Thanks Keith, all this is helpful as I’m still tweaking things. I don’t need fenders right now, so non-rubbing space is my main focus.
Also, I’ve been having fun measuring the same tire on different rims, since we all know that tire fit depends on more than just the nominal size on the side of the tire. Here are the actual widths I found for a 700x32 Gravel King SS tire installed on three different inner diameter rims (in parentheses), each inflated to 60 psi with tubes. Mavic Open Pro (15mm) - 30mm wide tire Velocity A23 (18mm) - 31mm Velocity Quill (21mm) - 32mm Obviously, with the exact same amount of rubber, the Quill install that measured 32 mm wide was less high (I didn’t measure that) than the Open Pro install at a narrow 30 mm.
