Hello,
First time poster, first road bike. I picked up my new road bike this morning at my LBS. The bike is a 2011 Specialized Secteur Elite Compact with SRAM/Apex. The only upgrade I had them perform was to swap out the stock tires for a pair of GP4000's (700x25) At the moment I weigh around 175lbs. The max tire pressure is 120 psi. Based on my weight and the tires, what would you recommend for tire pressure for the back/front? My primary concerns are flats, comfort, and tread life. Based on the little research that I've done, I'm thinking something along the lines of 105/95-110/100. Does this sound reasonable? Could I go even lower? I live in NH so lots of hills, back roads, and the roads aren't in the greatest condition. I took a look at that 15% tire drop graph and that put me at around 110/70. 70 seems kind of low to me, even for the front tire, but what do I know. Anyhow, I welcome all suggestions. I realized it's not an exact science but I'm just trying to find a good starting point that should produce decent results all around. Thanks in advance!
