Forgive the question but I'm having a bit of a senior moment I think 🤔
Rear shock travel is 102mm or just over 4", so to achieve 30% static sag the shock needs to compress 30.6mm. Simple so far, but...
The shock is mounted at an angle, so the rear wheel travel is not 102mm? So, measuring sag to the rear spindle means nothing unless someone knows what the rear wheel travel is.
A long shot I know but does anyone know the rear wheel travel on a V85tt please?
