CONSUMER SAFETY

WARNING: RIDING A BIKE IS DANGEROUS. NOT PROPERLY MAINTAINING OR INSPECTING YOUR BIKE AND
IT’S COMPONENTS IS EVEN MORE DANGEROUS. IT IS ALSO DANGEROUS TO NOT READ AND FOLLOW
THESE INSTRUCTIONS.

1. NEVER REMOVE STEERER TUBE FROM CROWN. THIS IS A PRESSED IN PART. REMOVING IT WILL
RENDER BOTH THE CROWN AND STEERER TUBE INOPERABLE.* MAKE SURE THE FORK CAPS AND ALL
FORK HARDWARE (brake bolts, pinch bolts, etc.) ARE TIGHT BEFORE EACH RIDE.

2. DO NOT PERFORM ANY MODIFICATIONS OR ADJUSTMENTS THAT ARE NOT OUTLINED IN THIS
MANUAL. SEE THE TUNING SECTION FOR MORE DETAILS.

3. INSPECT YOUR FORK BEFORE EVERY RIDE. INSPECT THE CROWN, TUBES, AND AXLE SEAT AREAS FOR

ANY SIGNS OF FATIGUE, BENDING, CRACKING OR OTHER DAMAGE. IF YOU NOTICE ANY TYPE OF
DAMAGE, DO NOT RIDE IT. RETURN IT TO YOUR DEALER OR TO WHITE BROTHERS FOR A COMPLETE
INSPECTION AND NECESSARY REPAIR.

4. PERFORM ALL RECOMMENDED MAINTENANCE ACCORDING TO THE MAINTENANCE SECTION OF THIS
MANUAL. FAILURE TO PERFORM MAINTENANCE COULD DRASTICALLY REDUCE THE FORK’S LIFE,
PERFORMANCE AND CAUSE YOUR FORK TO BE A SAFETY HAZARD.

5. WHITE BROTHERS RECOMMENDS THAT YOU WEAR PROPER SAFETY EQUIPMENT EVERY TIME YOU
RIDE, INCLUDING APPROVED BICYCLE HELMET. NEVER RIDE AT NIGHT WITHOUT LIGHTS.

6. ALWAYS USE GENUINE WHITE BROTHERS PARTS. USE OF AFTERMARKET REPLACEMENT PARTS AND

UPGRADES VOIDS THE WARRANTY AND COULD CAUSE STRUCTURAL FAILURE.

7.WHITE BROTHERS FORKS ARE DESIGNED FOR OFF ROAD USE ONLY. THEY ARE NOT EQUIPPED WITH

REFLECTORS FOR ROAD USE. IF YOU ARE GOING TO USE YOUR FORK ON THE ROAD, HAVE A DEALER
OR MECHANIC INSTALL REFLECTORS THAT MEET THE CONSUMER PRODUCT SAFETY COMMISSION’S
REQUIREMENTS.

*IF SERVICE BECOMES NECESSARY OR REMOVAL OCCURS, PLEASE CALL WHITE BROTHERS CUSTOMER SERVICE FOR PRODUCT

EVALUATION AND DIAGNOSIS.

INTRODUCTION

Thank you for purchasing your new White Brothers fork. Our forks are designed to help you perform at your absolute peak.
Your new White Brothers fork has oil damping and is air sprung for light weight performance. The air spring and damper is
set stock to satisfy a wide range of rider weights and riding styles. Fine tuning can be easily accomplished by changing air
pressure and external damper settings. See the tuning section for details. Steering accuracy is improved over conventional
MTB forks by utilizing superior materials and design. These include oversized 32mm fork tubes, a torsion box design steering
crown with pressed in tubes, a one piece billet brake arch and extra thick drop-outs. The WB bootless design allows a
considerable amount more slider/stanchion overlap than competitor forks which increases fork steering accuracy. Every effort
has been made to make White Brothers forks very light and perform at a level superior to other forks on the market. To ensure
peak performance, proper installation and periodic maintenance is required. When riding on public land, please respect the
rights of others and stay on established paths and trails. By riding responsibly, you are helping ensure the future of our sport.

FORK INSTALLATION

White Brothers forks feature a 1-1/8” threadless steer tube. If you have a threaded type fork on your bicycle, consult
your dealer for the appropriate upgrade parts necessary to convert to a 1-1/8” threadless steerer tube.

1. Remove your old fork from the bicycle. Measure the diameter and length of your old forks steerer tube to ensure
that the White Brothers steerer tube is the correct diameter and sufficient length for the installation.

2. Remove the crown race from your old fork.

3. Press the crown race onto your new White Brothers fork.(see Figure #1)

4. Preassemble the headset by sliding the fork steerer tube through the bearings. Then install the headset upper race,

headset spacer (optional), and stem onto the fork steerer tube. Adjust with optional spacers to your preferred height.

(See Figure #2) Refer to the headset owners manual if there is any questions about the pre-assembly.

5. Mark the steerer tube at the top of the stem. The steerer tube will now need to be cut to the correct length.

Disassemble and cut 3mm (1/8”) below the mark. Consult your dealer or mechanic if you don’t have the proper
tools to cut the steerer tube.

6. The star fangled nut must now be installed into the steerer tube. If you don’t have the set tool, we recommend

dealer installation of this part. (See Figure #3)

7. Clean and grease all headset bearings and races to prepare them for assembly. Note: Replace the bearings if there is
any sign of wear or corrosion.

8. Now loosely assemble the headset, stem and handle bars as done in step four.

9. Install the headset top cap into the star fangled nut. Tighten until there is no play in the steering. The fork should

rotate freely in the head tube. Straighten the stem in relation to the front tire and tighten the pinch bolts on the stem.
If there are any questions consult your dealer or mechanic.

10. Install your front brake and adjust according to the manufacture instructions.

11. Install and tighten the wheel in the front fork. Tighten the 20 mm thru axle nut and the pinch bolts.

12. Check to see that the brakes are adjusted and properly working. Make sure that the brake cable does not interfere

with any part of the bike when the fork is compressed and released.

Warning: When installing the wheel or a new tire, check for minimum clearance. Measure from the highest point on

the tire to the under side of the crown. There must be 1/8” or 3mm more clearance than the fork travel to ensure
adequate clearance in all riding conditions. Any less clearance can result in the tire hitting the crown resulting in
serious injury or death.
