Rear Shock PSI loss
Hey buddies,
I would like to know from you guys what the "norm" or "average" PSI loss is in the rear shock in relation to use...I know if i pump it to 115 its not going to stay at 115 forever.
I pumped my shock up last Saturday, and I have probably put about 20 miles on it give or take a few, of variable condition riding - about half and half hard and easy...Here it is Thursday, I check my PSI and it looks like I might have lost 2 to 5 PSI (my shock pump blows off around 7 - 10 PSI when removing it from the shock...so I filled it up to about 127 PSI...and when I checked it today it was right at 115 PSI)...my sag is normally right at a 1/4 inch and today it was about 1 or 2mm more than that...im probably being anal about it, but for future reference I would just like to know what is the "normal" amount of PSI to be lost in a given amount of time/milage...Hope this post wasn't too confusing...
Thanks!

Use your micrometer (or whatever it is you're employing above to determine your sag to the millimeter) and measure the exposed shock shaft. Per Rock Shox website, it'll be either 1.5 or 2.0 inches. Take 15-30% of that number, and that's how much sag you should be running. Feel free to experiment and see what feels good to you. Remember that if your shock is not bottoming occasionally, you're wasting travel.
