6. The star fangled nut must now be installed into the steer 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 according to the manufacturer’s instructions until
there is no play and the fork turns smoothly.
10. Install your front brake and adjust according to the manufacturer’s
instructions.
11. Install the wheel on the fork. Proper installation of both the QR and bolt-
on axle is communicated in the next section of this manual.
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 and
is secured under the brake hose clamp on the fork brace. Make sure your
brakes are adjusted and functioning properly, and the brake hose does
not interfere with any part of the bike when the fork is compressed and
released.
IMPORTANT BRAKE INFORMATION:
THE RIBBON FORK FEATURES A POST MOUNT FOR 180mm
ROTORS. SHOULD YOU WANT TO USE A LARGER ROTOR, MAKE
SURE TO USE THE APPROPRIATE DISC BRAKE ADAPTOR AS
RECOMMENDED BY YOUR BRAKE MANUFACTURER. FAILURE TO
DO SO COULD RESULT IN SERIOUS INJURY OR DEATH.

The Ramp Control unit is located within the air spring assembly, and adjusted
via a 16-position knob on the top of the spring-side fork leg. Your fork comes
from the factory tuned 5 clicks from the open, most-linear position. Clockwise
adjustment of the knob will reduce the fork’s tendency to bottom-out on hard
hits and increase the ending-stroke spring curve.
Ramp Control gives you the ability to
adjust, on-the-fly, the air spring’s ending-stroke
curve. Part high-speed compression damping,
part bottom-out control, Ramp Control is
completely independent of your damper or air
spring pressure settings. All MRP forks feature
super-supple small-bump compliance, but with
Ramp Control you can set your fork up to be super plush but still resist
bottoming. Cadillac-plushness not your thing? Dial back the Ramp
Control and up your pressure to enjoy a more linear fork that rides
high but uses every inch of travel effectively.
Adjusting your Ribbon to 8 or more clicks of Ramp Control will
help you stay in control on particularly steep, violent, or fast trails by
preserving the last portion of the stroke for big hits.
The compression adjustment knob is located on the top of the damper-
side fork leg. There are 8 positions of adjustment. Your fork comes from the
factory in the first, least-damped position.
As you turn the dial clockwise, you are
adding compression damping or slowing the
forks compression stroke. It is an adjustment
that is subtle, and often overlooked, but
can make a big difference in how your fork
performs. Aggressive riders tend to like more
compression damping because it provides a
firmer, more positive feel. Comfort oriented,
less aggressive riders tend to like less because
it allows more small bump sensitivity. Do not confuse compression
damping with spring rate (air pressure). They are very different
adjustments, and while adding compression damping may make the
fork feel “stiffer”, it is not changing the spring rate.
In the eighth, final position of the compression adjustment
range our hydraulic valving provides a highly-damped, supported feel
perfect for smooth trails, road stretches and transfer stages. Should
you encounter any rough patches however, the valving will “blow-off”
and allow the fork to cycle and your front wheel to track.
