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 sufficient 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 off-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.
