How to Measure Sag
1. Set fork/shock to fully open (no lockout)
2. Push O-ring up against fork seal
3. Sit on bike in riding position — hands on bars, feet on pedals
4. Carefully dismount without bouncing
5. Measure O-ring distance from seal — this is your sag in mm
6. Adjust PSI 5 at a time until within target range
