FORK INSTALLATION
1. Remove the existing fork from the bicycle. Remove the crown race from the old fork. Measure the steerer
tube length of the old fork and transfer this measurement to your new Marzocchi fork's steerer tube.
If you don't have an existing fork, measure the headset stack height (headset parts and frame head
tube) and refer to your stem manufacturer's instructions to be sure there will be enough clamping
surface for the stem.
2. Cut the steerer tube to the proper length. Mark the steerer tube and cut it to the proper length.
Prior to any cutting, consult your headset and stem manufacturer's
instructions to ensure that you have enough steerer tube length for
clamping the steerer and stem. Improper installation can lead to a
separation of the stem from the steerer, resulting in a loss of control of
the bicycle and SEVERE INJURY OR DEATH.
3. Install the headset. Always use a new threadless headset and follow the headset
manufacturer's instructions.
4. Install a 39.8 mm crown race for 1 1/2 in. steerer tubes. Use a crown race setter to install the crown
race firmly against the top of the crown.
5. Use a star-fangled nut installation tool to install the star nut 4-10 mm below the top of the steer tube.
6. Install the fork onto the bicycle. Install the headset bearing parts and stem in accordance with the
headset manufacturer's instructions, and adjust the headset preload accordingly until you feel no
excessive play or bearing drag. Tighten the stem clamping bolts to the stem manufacturer's torque
specifications.
7. Install the brakes according to the brake manufacturer's instructions.
Maximum rotor size for BOMBER Z1 is 230 mm. Maximum rotor size for
BOMBER Z1 coil is 203 mm.
The disc brake caliper mounting bolts must have 10-12 mm of
thread engagement with the fork. Use a torque wrench to tighten
the caliper mounting bolts to the disc brake manufacturer's
specification, but do not exceed 10.2 N•m (90 in-lb). Improper
installation can lead to brake failure, resulting in a loss of control of
the bicycle and SEVERE INJURY OR DEATH.
8. Route the front disc brake hose or cable housing to the inside of the
lower leg, and through the supplied disc brake housing guide. Use a
torque wrench to tighten the disc brake hose guide screw to
0.9 N•m (8 in-lb).
