09.After repeating the process to install the left side, installation was complete. Next, Kevin set the sag. Ride sag is the amount the suspension compresses with the weight of the rider and/or passenger/luggage. Setting ride sag is important as it sets the shock up to properly handle bump travel and extension travel. Progressive recommends a ride sag of 1/3 of the wheel travel. For example, if a bike has 3 inches of wheel travel, the ride sag would be set at 1 inch. To set the ride sag, Kevin fully extended the rear shocks and took a measurement from the center of the axle to the center of the fender mount.
