I run 80 regularly and when cold it's over that. I know it kicks open somewhere above 80 I have seen it on the gauge but I forget what the highest pressure I have seen was.I am absolutely sure it was quite a bit over 80 though and the 80 PSI is an sbsolute certainty when out riding.

I learned all I need to know about life by killing smart people and eating their brains.
