The shock only adjusts for pre load, as I'm sure we all know, so adjusting it only really raises or lowers the ride height for any given weight and doesn't make the suspension harder or softer. She has the shock set on the lowest setting just so she can touch the ground, even if one were to believe that it makes a difference its on its most compliant setting which should make it more comfortable. Having ridden the bike myself, I find the seat to be like sitting on ply board, it needs to be re-worked. Trouble is the foam is very thin and she can't afford it to be any higher. I think she'll have to talk to a few seat modifiers and figure out which one can do the best job for her needs, possibly during the winter months.
