My ring is always completly at the bottom of the stanchion. I also put some more psi into the damper. It got poppier but the ring is still all the way down.
This Bike is pretty good speced. Only thing i could complain about, are the long cranks. 165mm would be better for groundclearence. I was riding the lower spec Cube Stereo 160 Hybrid SL and it was very annoying hitting roots and rocks very often...
