SETTING AND ADJUSTING SAG (air Shocks) 

cont’d

Sag Recommendations chart (air shocks)

1. Pump the main air chamber to a psi equal to 100% of rider 

weight in pounds (2.2lb = 1kg). 

2. Push the rubber O-ring that is around the shock shaft all the 

way against the base of shaft (closest to shock body). 

3. Position the bicycle next to a wall so that they can sit on the 

bike with both feet on the pedals while steadying themself 

with one arm. Have them gently sit on the saddle without 

bouncing. Get them to dismount gently without bouncing and 

take note of how far the O-ring has moved down the shaft. 

Measure the distance the O-ring has moved (Figure 2). 

4. Add or remove air until desired shock movement is ob-

tained. To achieve a high level of accuracy it’s best to carry 

out this procedure while the rider is wearing a normal riding kit 

including shoes, hydration pack, any tools, etc. The shock 

pump must be removed every time you check the sag.

NOTES

 

Please refer to the shock manufacturer’s technical manual for minimum and maximum 

working pressures for the shock. Refer to the Sag Recommendation Guide on the next 

page for proper sag measurement. 

If there is no O-ring on the shock body or you cannot clearly see the shock shaft then 

please use the method for coil sprung bikes using the eye-to-eye measurement as 
described on Page iii of this manual.
