Checking Sag #'s without oil...

Recommended Posts

Is this practice acceptable?

I'm in the middle of a frankenbike project, and would like to verify my spring choices before sealing everything up. Would it be okay to set front and rear sag without having the full oil height in the fork and shock? Theoretically the oil and valving should not come into play while the suspension is static during a sag check.

I realize I will want a bit of oil to alleviate stiction, but it would be nice to verify the springs are in the ballpark before buttoning everything up. I do plan on averaging the sag numbers from compressed and extended as per the usual practice.

Let me know what you think...

the only issue I can think of is the shock nitrogen pressure.. which has a small contribution to preload... how much, I have not measured.. ... theoretically, you should get the info you need just fine without oil

i dont think it will work properly, you are right it should not matter much but i think it will make a difference.
