Installation
Judy XC, SL, and Race Installation Instructions
It is extremely important that your RockShox fork is installed correctly by a qualified technician. Improperly
installed forks are extremely dangerous and can result in severe and/or fatal injuries.
1. Remove the existing fork from the bicycle and the crown race from the fork. Measure the length of the fork
steerer tube against the length of the RockShox steerer tube. The RockShox steerer tube may need cutting to
the proper length. On threadless steerers (Aheadset design), make sure there is sufficient length to properly
clamp the stem (refer to stem manufacturer's instructions).
Important: Do not add threads to RockShox threadless steerers. The steerer tube crown
assembly is a one-time press fit. Replacement of the assembly must be done to change length,
diameter, or headset type (threaded or threadless). DO NOT remove or replace the steerer tube,
this could result in loss of control of the bicycle with possible serious and/or fatal injuries.
2. Install the headset crown race (29.9mm for 1-1/8" steerers) firmly against the top of the fork crown. Install
the fork assembly on the bike. Adjust the headset so you feel no play or drag.
3. Install the brakes according to the manufacturer's instructions and adjust brake pads properly. Use the fork
only with V-type or hydraulic cantilever brakes mounted to the existing mounting posts or disc style brakes
mounted through the mounting holes provided. Do not use any cantilever brake other than those intended by
the brake manufacturer to work with a hangerless brace.
4. Adjust the front wheel quick release to clear the dropout's counter bore. The quick release nut must be
tightened after the wheel is properly seated into the dropouts counter bore. Make sure four or more threads
are engaged in the quick release nut when it is closed. Orient the quick release lever in front of and parallel
to the lower tube in the locked position.
5. Keep in mind tire clearance as you choose tires. Maximum tire size is 2.2" wide or 335mm radius. Be sure to
check this radius whenever you change tires. To do this, remove the spring stack (per instructions on
following pages), and compress fork completely to make sure at least 5 mm of clearance exists between the
top of the tire and the bottom of the crown. Exceeding the maximum tire size will cause the tire to jam
against the crown when the forks are fully compressed.
6. Hangerless Reflector Bracket Installation: Orient black reflector bracket to the front of the fork with the 90
degree bend under the fork brace. Place the .040" thick flat washers onto the hex bolt and insert this
assembly through the lowest oval hole in the bracket and through the hole in brace. Place star washer onto
bolt and thread nut onto bolt at back of brace. Torque reflector bracket nut per "Maintenance/Torque
Tightening Specifications" section.

Judy XL Installation Instructions
1. Remove the existing fork and lower headset race from the bicycle.
2. Before you install a Judy XL on the bicycle, verify that the fork has been supplied with the correct upper
crown. Refer to Fig. 2 for upper crowns available for Judy XL and to maximize fork stiffness by proper
selection and orientation of the upper crown.
3. The steerer tube may need cutting to
proper length. To cut the steerer tube,
removal of the upper tubes is required, or
the upper tubes will be in the way when
cutting the steerer tube to proper length.
The steerer tube length is determined by
the following parts: Judy XL upper crown
steerer clamp length, stem steerer tube
clamp length, frame head tube length and
top and bottom headset stack height (see
Fig. 3). To ease in the assembly, do not
install the Judy XL upper crown on to the
upper tubes until the steerer has been cut
to the proper length and the lower crown
has been fastened in the required position.
Important: Do not add threads to
RockShox steerers. The steerer tube
crown assembly is a one-time press
fit. Replacement of the assembly
must be done to change length,
diameter, or headset type (threaded
or threadless). DO NOT remove or
replace the steerer tube, this could
result in loss of control of the bicycle
with possible serious and/or fatal
injuries.
4. Install the headset crown race (29.9 mm
for 1-1/8" steerers) firmly against the top
of the fork crown once the steerer tube has
been cut to proper length.
5. Install the upper tubes into the lower
crown and locate the lower crown so that
170mm of upper tubes extends above the
lower crown. Before tightening the lower
crown bolts, verify that one lower crown
shim is located between the slot of each upper tube clamp and are free of debris or other material to insure
proper performance. Rotate the lower crown shim to prevent the shim edge from scratching the upper tube.
Torque the lower crown bolts per the "Maintenance/Torque Tightening Specifications" section.
Important: The lower crowns must be located with 170 mm of exposed upper tubes above the
lower crown and the lower crown shims must be used with the Judy XL lower crown. Failure to
follow these instructions can cause the bottom of the lower crown to hit the front tire, or result
in additional stresses to the upper tubes resulting in the loss of control of the bicycle with
possible serious and/or fatal injuries.
6. Assemble the headset, upper crown and stem on the bicycle. Adjust the headset so you feel no play or drag.
Complete the installation of the headset and stem according to the manufacturer's instructions. Torque all
the upper crown bolts per "Maintenance/Torque Tightening Specifications" section.
7. Complete the rest of the Judy XL installation by following steps three through seven under "Installation
Instructions (Judy XC/SL/Race)."
