OWNER’S
MANUAL
IMPORTANT CONSUMER SAFETY INFORMATION
WARNING: RIDING A BIKE IS DANGEROUS. NOT PROPERLY
MAINTAINING OR INSPECTING YOUR BIKE AND ITS COMPONENTS
IS EVEN MORE DANGEROUS. IT IS ALSO DANGEROUS TO NOT READ
AND FOLLOW THESE INSTRUCTIONS.
Thank you for choosing MRP. This owner’s manual is your
reference guide to using and fine-tuning your suspension fork
for optimum performance and comfort. It also provides important
information about the proper maintenance of your fork. Carefully
read this manual before installing your fork. If you need further
assistance, our experienced team is able to advise and assist you to
find the exact set up to meet your personal needs.
The fork is an important part of your mountain bike and
this owner’s manual explains how to install and use it properly. We
recommend that it be installed by a qualified bicycle mechanic.
Improperly installed forks might cause serious harm to you and may
severely damage your mountain bike. Never take any chances with
your safety. Before installing and using your new fork, carefully read
this owner’s manual to learn the correct installation and adjustment
procedures and avoid the consequences of an incorrect installation
or improper adjustment.
When your fork requires an oil change or other internal
maintenance, MRP and experienced suspension service centers are
best qualified to provide the necessary service or repairs.
FORK INSTALLATION
1. Remove your old fork from the bicycle. Measure the diameter and
length of your old fork’s steerer tube to ensure that your new steerer tube
is the correct diameter and sucient length for the installation. If your MRP
fork has a tapered steerer tube, be sure to leave enough room above the
taper to allow for proper stem installation.
2. Remove the crown race from your old fork.
3. Press the crown race onto your new fork. (See Figure #1)
4. Preassemble the fork on the bike with the headset, stem, and spacers
(optional). Refer to your stem manufacturer’s instructions to determine how
much room is needed to clamp the stem.
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.
Rider B:
Rides very technical, predominately slow-
speed trails. The fork is a Ribbon 29 140mm
and settings would likely be:
Air Pressure:
Positive pressure set at recommended value
for weight and negative pressure set slightly
higher for super supple small bump perfor-
mance.
Rebound:
Set at recommended value for weight.
Compression:
Little to no added damping.
Ramp Control:
12 clicks - resisting bottom-out on all but the
biggest hits, but maintaining a plush overall
stroke due to negative pressure setting and
light low-speed compression damping.
Rider A:
Races enduros, rides with an aggressive
all-mountain style. The fork is a Ribbon 27.5
170mm and settings would likely be:
Air Pressure:
Positive pressure slightly higher than recom-
mended and negative pressure set the same
for a neutral o-the-top feel.
Rebound:
Generally on the faster end of the recommend-
ed range (for improved high-speed control).
Compression:
Knob position in middle of range to filter out
some rider-induced movement caused by
standing pedaling.
Ramp Control:
6 clicks - providing some additional bottom out
resistance for fast, square edged hits.
SAMPLE RIDER SETUP PROFILES
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 eectively.
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 dierence 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 dierent
adjustments, and while adding compression damping may make the
fork feel “stier”, 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-o”
and allow the fork to cycle and your front wheel to track.
