Tuning Rock Shox Dual Air Forks
The Air
- The sum of the pos/neg pressures relate to the fork's actual spring rate.
- The pos/neg distribution adjusts ride height.
- Make sure to remove all the spacers from inside the fork. Use pos/neg air Distribution to adjust the bump travel.
- Simple.
The Floodgate
Make sure to set the floodgate to the lowest setting that produces a solid pedaling platform. The fork should be active over any bumb in the trail.
The Rebound
Rebound should be set to provide the plushest 'feel' on rough singletrack. The forks should not feel harsh as that would mean that you have too much (packing) or to little rebound (spiking).
The Oil
The stock damping fluid on 2007 Rock Shox products is Maxima 85-150 Fork Fluid. The ISO viscosity of this oil is 15.90, a good starting place for any fork either motorcycle or bicycle.
I tend to replace fork fluids with Red Line Suspension Fluid. 28% Red Line (Extra Light,Blue) & 72% Red Line (Light,Yellow) will duplicate ISO 16.
Other damping and lubrication options are provided by '15wt (Stock)' oil. Assuming that they are using Maxima for this as well, then the viscosity of this would be ISO 46. Red Line equivilant is 57% Red Line (Medium,Red)& 43% Red Line (Heavy).
