wow 26 is low - especially for 190 lb rider … (add weight for clothes / shoes, tools, and water bottles and then over 200 lbs)
I am a big fan of people experimenting with tire pressures - as it is very dependent upon the tire (along with the person, the bike, the track, etc). With the old Gravelkings, anything less than 32 psi or more than 36 psi felt terrible.
