Introduction
Original instructions (user manual/instructions for use) are written in English. All other
languages are translations of the original instructions (user manual/instructions for use).
In case of any dispute, the user manual in English prevails.
This user instruction manual is developed for your Greyp bike only. It contains important
safety, performance and technical information, which you should read before your rst ride
and keep for reference. You should also read the entire User Manual, because it contains
additional important general information and instructions that you should follow.
If you do not have a copy of the User Manual, please download it for free at
www.greyp.com or obtain it from your nearest Authorised Greyp Retailer. In case of
discrepancy, the english version shall prevail.

General warning
This manual contains many “WARNINGS” and “CAUTIONS” concerning the consequences of
failure to maintain or inspect your bike and of failure to follow safe cycling practices.
The combination of the safety alert symbol and the word WARNING indicates a potentially
hazardous situation which, if not avoided, could result in serious injury or death.
The combination of the safety alert symbol and the word CAUTION indicates a potentially
hazardous situation which, if not avoided, may result in minor or moderate injury, or is an alert
against unsafe practices.
Many of the WARNINGS and CAUTIONS say you may lose control and fall. Because any fall
can result in serious injury or even death, we do not always repeat the warning of possible
injury or death.
As it is impossible to anticipate every situation or condition which can occur while riding, this
User Manual makes no representation about the safe use of the bicycle under all conditions.
There are risks associated with the use of any bicycle which cannot be predicted or avoided,
and which are the sole responsibility of the rider.

5 HANDLEBAR POSITIONING
1. Rotate the handlebar to its natural position (≈90° to the frame, “centered ”).
2. Using the tool (three-arm hex key number 5), lightly tighten the two bolts on the stem.

1. Guide your wheel into the fork and guide the rotor between the brake pads.
2.
Tighten the axle - line up your hub with the holes at the bottom of your fork. Check which side of the fork
is threaded and push the axle in from the opposite side. Turn the three-arm hex key number 6 clockwise to
thread the axle into the fork.
7 PEDALS MOUNTING (G6.1, G6.2, G6.4, G6.5, G6.6)
1. Take the pedals out of the box, grease
the thread and tighten them using the
tool (three-arm hex key number 6) (see
picture above).
2. Pay attention to the direction of
rotation
while tightening. The thread
on the right pedal is right-handed
(standard). The direction of rotation for
tightening is anti-clockwise. The thread
on the left pedal is left-handed so the
direction of rotation for tightening is
clockwise.

CHECK (G6.3)
1.Take the pedals out of the box, grease
the thread and tighten
them usingthe tool
(L shaped 8 allen wrench - see picture).
2. Pay attention to the direction of
rotation
while tightening. The thread on
the rightpedal isright-handed (standard).
The direction of rotation for tightening
is anti-clockwise. The thread on the left
pedal is left-handed so the direction of
rotation for tightening is clockwise.
8 HANDLEBAR MOUNT
1. Slightly loosen the 2 bolts on the stem.
Tighten thetop cap (headsetbolt) to 6Nm
using the three-arm hex key number 5).
2. Center and tighten the 2 bolts on the
stem. The easiest way to get everything
“centered” is to stand in front of your bike
and hold the front wheel between your
feet and legs. Tighten the 2 bolts on stem
(headset bolt) to 12Nm.
9 CHECK
Grab the front brake and use the bars to push/jolt the bike forward. If you feel that the headset is loose (a clinking
sound, or any movement other than the rear wheel coming off the ground), tighten the top cap, but
be careful how much you tighten it (three-arm hex key number 5). The top cap bolt will determine how
loose or tight your headset is, so it plays a major role in the steering and feel of your bike. Tighten the bolt
a little at a time and between each turn.
Once the looseness in the headset is gone, it should be tight enough.
Give the handlebar a turn to the left and
right
to make sure they still move smoothly. If the movement is tight, you’ve gone too far. Back the stem

INTRODUCTION

cap off a quarter to half a turn and try again. Once there is no looseness in the headset and the handlebar
is smoothly turning, you need to take the tool (three-arm hex key number 5) and tighten the two bolts on
the stem (see picture).
Flip your bike over and spin your wheel: by spinning your wheel, you will make sure your brake pads are not
rubbing on the rotor. If your wheel does not spin, it could be crooked in the fork’s dropouts. Flip your bike
back, loosen your axle, push down on the wheel and tighten the axle again.

SUSPENSION
Rear Suspension (if applicable)
Suspension sag can be used to set the proper suspension spring rate for the rider. Sag is
the amount (percentage) the suspension compresses when the rider, including riding gear,
is seated on the bike in the riding position. Setting the proper sag allows the wheels to
maintain traction without using too much of the travel reserved for shock absorption. More
sag increases small bump sensitivity, while less sag decreases small bump sensitivity. Set the
spring sag before making any other tuning adjustments
Before setting sag, set the dampers to the full open positions. Rotate the adjusters counter
clockwise until they stop. Set the shock to the open position. Beginning with the shock fully
deated, pressurize the air spring chamber to 100 psi. Do not compress the suspension with
the pump attached. Fully compress the shock ve times to equalize the positive and negative
air springs. Compress the shock once more to equalize air pressure. With your riding gear
on, and an assistant holding the bike, step onto the vehicle and lightly cycle the shock two to
three times.
While seated on the bicycle, have an assistant slide the sag o-ring against the wiper seal.
Gently step off the vehicle without compressing the shock. Note the sag percentage where
the o-ring stopped. Usually sag percentage for shocks is around is 25% - 35%. Sag can be set
±5% as preferred. If your target sag percentage is not achieved, air pressure must be adjusted.
Increase air pressure to decrease sag. Decrease air pressure to increase sag.
Additional adjustment
Depending on the exact model of the shock, there are various adjustments that can be made,
and some of them are rebound, low speed compression, high speed compression, threshold,
lockout and other. For further information please contact your Greyp dealer or visit shock
manufacturers website.

GENERAL NOTES ABOUT RIDING

Front suspension
Rebound damping controls the suspension fork extension/return speed, which affects traction
and control. Optimal rebound damping allows the fork to extend at a controlled speed and
maintain traction and control. Rebound that is too fast allows the fork to extend too quickly,
which causes the wheel to bounce off objects and the ground resulting in a pogo effect.
Rebound that is too slow prevents the fork from extending quickly enough to regain contact
with the ground or prepare for the next impact. Rebound damping can be tuned to rider weight,
spring rate and travel, as well as for terrain and rider preference. As the air pressure or spring
rate increases, the extension/return speed increases. To achieve the optimal setting, rebound
damping may need to be increased when air pressure or spring rate increases.
Additional adjustment
Depending on the exact model of the fork, there are various adjustments that can be made,
and some of them are rebound, low speed compression, high speed compression, lockout
and other. For further information please contact your Greyp dealer or visit fork manufacturers
website. Usually on fork crown there is level or nut adjuster which if you rotate you can make
fork absorption softer or harder.
Recommended tire pressure
WARNING — If the maximum pressure values in this manual and values on the side wall of a
tire are in any way different, please refer to the ones that are marked on the tire’s sidewall or
wheel (whichever is lowest). Never inate a tire beyond the maximum pressure marked on the
tire’s sidewall. Exceeding the recommended maximum pressure may blow the tire off the rim,
which could cause damage to the bike and injury to the rider and/or bystanders.
