Judy forks are designed to sag when you are sitting on your bike. Sag is the
compression of the fork caused by the rider's weight. Correct sag allows the front
wheel to follow the contour of the terrain as you ride. Sag is adjusted by turning the top
cap preload adjusters. Turning the adjusters clockwise increases spring preload
(stiffness of the spring) decreasing sag. Turning it counterclockwise decreases spring
preload which increases sag. Sag should be set between 10 and 25 percent of the
travel selected. To change travel refer to the owner's manual.
To measure sag, install a zip-tie on the upper tube of the fork flush against the XXX
seal. Sit on the bike in your normal riding position, with your elbow against a wall to aid
balance. Step off the bike, and measure the distance between the XXX seal and the zip-
tie. This is your sag. (Fig. 1 & 2)
To determine the existing travel, measure the distance between the crown and XXX
wiper seal. (Fig. 3)
Judy Race: 63 travel = 94 mm / 80 travel = 111 mm / 100 travel = 128 mm
Judy SL/XC/C: 63 travel = 90 mm / 80 travel = 107 mm / 100 travel = 124 mm

This guide will help you quickly find your preferred settings. Remember, what might be your perfect set-
up may not be the same for someone else with the same bike and equal weight – we, like our bikes, are
individuals! Left and right are as viewed from the saddle.

ADJUST YOUR SAG IN ACCORDANCE WITH YOUR MODEL, TRAVEL and STYLE
If you’re unable to achieve your correct sag by turning the preload adjuster, you may
need to change the springs. All RockShox products are designed for the ‘average’ rider's
weight (160-180lb or 70-80kg) and style. If you are not ‘average’ it may be necessary to
change the spring in your fork to achieve ultimate performance. Use the guidelines
below for spring selection. Note: spring selection depends on travel selected.
