OP, I think PSI info is a bit meaningless without knowing the weight of the rider. How much do you weigh?

I would tend to agree with that. I weigh 59-60 and run 25s on some rear tires. I find that there is no problem running them under 100 in the dry. There seems to be enough volume to prevent them from pinch-flatting on the deep rimbeds seen on many of the modern aero wheels.
At 70kg I run the Roubaix at 70/85. Just use this as a base for the minimum pressure you can run and adjust from there:

Less is more.
80-100psi, I weight 78kg-80kg
thanks mainly just looking for a good baseline and where to begin. Now I am debating between making a few transition to tubulars all the time, training and racing.. Since need a second set of wide wheels for pit (or follow car) for racing. Cant imagine having to swap to my cheap 19 width rims in a race if flat haha

At 68 kg, I've found that 80/85 in 25mm Roubaix on the wider Bora rims is the ideal feel for me, though I did get one pinch flat from a sharp rock.
