I sold mine two years ago but from memory…
3 road preload setting and 3 road damping settings. The preload only adjusts the damping at the rear in the road settings.
Plus 2 “off road” preload settings where the front shock also gets added preload to match the rear. Damping gets called something different but afaik is the same damping as in road mode.
There’s three preload positions for the shocks: +25%, +50%. and + 90%.
So in 1 helmet the both shocks are at 25%. In two helmets front stays at 25% but rear will be at 90%.
In low mountains both at 50%, high mountains both at 90%.
If a shock needs recalibration via a gs911 all it does is recalculate where the 25/50/90% positions are. A calibration may also recalculate the damping adjustment but I don’t know for sure.
