TUNING
To get the most out of your White Brothers fork, it is important that you tune the fork to
fit your weight, riding style and the terrain you ride.
fit your weight, riding style and the terrain you ride.
INITIAL BREAK-IN PERIOD
Your new fork is designed to break-in over a period of 10 hours or more of riding. As
all the parts bed into each other, the stiction (friction) of the fork decreases and the
sensitivity increases. After the initial brake-in period, fine tuning the air pressure and
damping adjustments may be beneficial to achieve the best possible performance.

TOOLS NEEDED:
High pressure air pump
15/16” socket with ratchet.
6mm Allen wrench
AIR SPRING /CARTRIDGE DAMPER
Your new White Brothers fork is designed with an air cartridge for air sprung support. An air
cartridge is a light weight, adjustable air sprung shock absorber, which screws into the fork
stanchion at the crown. The following guidelines for checking and adjusting your cartridge
will enable you to enjoy maximum performance from your fork.
stanchion at the crown. The following guidelines for checking and adjusting your cartridge
will enable you to enjoy maximum performance from your fork.
1. First, test ride the fork over easy terrain. If after riding the fork over varied terrain you
decide that more tuning is necessary, continue to the next step.
2. The compression or spring of the fork can be changed two ways: 1) by changing air
pressure in the cartridge and 2) adjusting the settings of the damper cartridge.

6. Compression adjustment (lockout) is done by turning the knob on the top of the right leg
and is a lockout when turned full clockwise. WARNING: The lockout is designed to be
used on smooth terrain only. DO NOT lockout the fork on rough terrain, bumps or drop-
offs. Turning the knob counter-clockwise from lockout, will provide less and less
compression damping. Less compression damping will increase the fork dive but will feel
smoother over small bumps. More compression damping will feel stiffer over small bumps
but will be more resistant to bottoming. The compression / lockout knob has ¾ of a turn of
adjustment. If more damping range is needed, contact White Brothers.

7. Rebound adjustment is done by turning the adjuster on the bottom of the right leg. Turn
the knob clockwise for slower rebound. To speed up rebound, turn the knob counter-
clockwise. Start with a middle setting and fine tune the rebound from there. Proper
rebound will allow the tire to track the ground over consecutive bumps. Too slow of
rebound will pack-up (feel stiff over consecutive bumps) while rebound set too fast will
cause the fork to top out. Adjustment range is 6 turns.

emove the snap in dust cap (use a finger nail or small screw
driver) so that the schrader valve stem is exposed.(see Figure #4)
You will need a high pressure shock pump to inflate the cartridge. Start with the stock
setting of 200 lbs. If the fork feels too soft or firm, fine tune the air pressure in five pound
increments until the fork sag (support) is approximately 15 to 25 percent of the total travel.
increments until the fork sag (support) is approximately 15 to 25 percent of the total travel.
Test ride after each adjustment until the air cartridge is at an adequate pressure. Generally
you will want a higher pressure for a 80mm fork and a lower pressure for a 100mm fork.
Reinstall the dust cap.
