I've got an SR Suntour XCM HLO 27.5" 100mm travel that comes with my bike. It has preload adjuster on the left and lock on the right.
What I wonder is how to properly adjust the fork softness/stiffness as I encountered some bumps with stiff feelings on the fork.
Also, if I lock it and turn the preload adjuster, I can turn it more than if I let the fork open. What causes this and should I lock it before adjusting the preload?
