Setting Sag - measurement question
Setting Sag - measurement question
I figure shocks have broken in and it's time to readjust the sag and damping. I'm reading conflicting issues with how to obtain the sag readings.
> Measure from Center of the top & bottom shock bolts
or
> Measure from the Flats of the top & bottom shock bolts
Let me know what you guys think.

Measure eye to eye because you're trying to measure sag as a percentage or length of what the shock's full stroke is.
measuring from fixed points, a fixed point to the top of the shock eye, etc. wont get you an accurate measurement unless you like figuring a few more Pythagorean theorem problems out as well.

What does it matter where you measure from ? If it is 1/3rd your travel when you get done that is all that matters.

An easy thing to measure is the spring length. Jack the bike up enough to get the weight off the wheel and measure, to provide a datum.

The pros do it this way.
And, I suggest that when you sit on your bike for the final measure, you should be in your "Attack" pose, not just sitting there upright like a sack of potatoes!

I agree with others in that it doesn't matter what is used, as long as your consistent. You're measuring SAG based on the actual stroke length of the shock and thus taking that SAG portion from the length you're measuring with, be it from bolt center or wherever.
