Hey all. Just got back from a nice 50 mile charity ride down here in Texas. The morning started in the 40's and its now 2:30 and 85.
My question is regarding inflation levels for cold morning starts. I ride an aluminum trek (1200) with 25mm Gatorskins. Under normal weather i pump to 120 psi and since i'm 6'2" and 170 lbs i get a slight sag in the rear.
What psi should i be pumping to at 40 degrees knowing that later in the ride the temp will climb? my fear is that i pump to 120 psi cold and then the psi will climb while riding and with temp increases.
