With the shocks selected above installed and the full weight of the rider(s) & gear on the bike as it will be ridden, measure the distance between the upper and lower shock mounts (center to center). If your measurement is less than the indicated Target Ride Length, increase the spring pre-load** to raise the bike until you achieve the Target Ride Length. If your measurement is more than the indicated Target Ride Length, reduce the spring pre-load** to lower the bike until you achieve the Target Ride Length. Achieving the Target Ride Length in this manner sets the rear suspension ride sag for optimum performance and comfort.
