6.3.2: REASSEMBLING THE REAR SUSPENSION
(For pictorial views of the assembly, refer to Fig. 2 on page 11)
Tools Required: Large Flat Blade Screwdriver
10mm A/F Spanner
Torque Wrench with 10mm A/F socket
The re-assembly of the rear suspension is basically the reverse of the disassembly proce-
dure in section 6.1. Starting with the shorter lower Quad Link (5), ensure that the link is
complete and correctly assembled (See Fig.4). Next make sure the lower Quad-Link (5) is
correctly orientated (see fig. 6) and pass a 90mm long M8 stud (8) through the lower
Quad-Link (5) and front triangle (6). Next take the rear shock (7) and assemble the upper
mount of the rear shock (7) using SKF LG/AF anti fret paste on the contacting surfaces,
into the upper shock mount of the Mainframe (6). IMPORTANT. Ensure the rear shock is
the correct way up, with the blue Pro Pedal lever facing forwards. Assemble the longer up-
per Quad-Link (4) onto the Mainframe (6), and pass a 78mm long M8 stud (9) through the
upper Quad-Link (4), the Mainframe (6) and through the front of the rear shock (7) until
the 78mm long M8 stud (9) is showing out the other side of the upper Quad-Link(4). You
should now have both upper and lower Quad-Links assembled onto the Mainframe (6), with
the rear shock (7) in position. Next lower the Swinging Arm (3) onto the rear suspension
assembly and position the Swinging Arm (3) onto the upper Quad-Link (4) first. Make sure
that the Inner Shield Washers (1, Fig.3) are present. Pass the Hollow Pin (13) into the up-
per Quad-Link (4) and Swinging Arm (3). Place washers (12) each side of the swinging arm
(3), making sure the flat side of the washer faces the swinging arm. Screw in both M5
countersunk capscrews (11) into either side of the hollow pin (13). Tighten both capscrews
(11) to the recommended setting. (Refer to the Tightening torque settings in Section 8.0).
Next rotate the Swinging Arm (3) down to attach it to the lower Quad-Link (5) and the rear
shock (7). Once you have the Swinging Arm (3) in the correct position, make sure that the
lower Quad-Link (5), the Swinging Arm (3) and the Rear shock (7) though holes are all
concentric with each other, and push through the last remaining 90mm long M8 stud (10).
Next re-fit the M8 Aerospace Nuts (3). IMPORTANT: before final tightening of the M8 Aero-
space Nuts (3), it is important to make sure that there is a balanced amount of thread
Fig.7: Maximum Thread Protrusion
showing through the M8 Aero-
space Nuts (2) on each side of
the upper and lower Quad-Link
assemblies, see fig. 7. Using the
small slotted screwdriver in the
end of the M8 studs (8, 9 & 10),
and the 10mm spanner, adjust
all 4 M8 Shafts (8, 9 & 10) ac-
cordingly. Refer to Fig. 9. Tighten
all M8 Aerospace Nuts (2) to the
recommended settings. (Refer to
the Tightening torque settings in
Section 8.0) Next make sure that
there is still a substantial amount
of Molykote 111 Silicon covering
all the KP5AX Bearings. Refit the
Bearing Caps (1) by screwing
them clockwise into the links.
Take care not to cross thread the

The front fork is pre-set with standard settings when you buy your Marin. Before rid-
ing, you will need to adjust the sag setting on the fork. This is to ensure it is set-up
correctly for your own body weight, so the fork will perform as intended.
To set sag on a front fork, you need to measure the amount the fork compresses
when you sit on the bike in the normal riding position. We recommend for the best
synergy between front and rear suspension systems to run approximately 16mm
(16%) sag on the Rift Zone front fork and approximately 23mm (16%) sag on the
Mount Vision front fork.
Sag on forks is controlled by adjusting the Air Spring pressure, or if you have a coil
spring fork, the rate of the coil spring inside the fork. This is not adjustable, and re-
quires the fork to be rebuilt with a different spring. Please consult your Marin Dealer
for more information.
Rebound Damping adjustment:
This adjustment fine-tunes the speed at which the wheel returns to its normal ride
height after hitting a bump. To demonstrate the effect of this function, turn the
adjuster to its slowest setting. Press down on the handlebars to compress the forks,
then release the load. The suspension recovers very slowly to its original position.
Repeat the above with the adjuster turned to the fastest setting and the difference
will be seen immediately the load is released. We recommend the optimum setting is
to adjust the re-bound damping to be as slow as possible, but not so slow that the
normal ride height is not recovered. On very rough terrain, if the front or rear of the
bike becomes progressively lower as more bumps are hit then the re-bound damping
is set too slow. On the other hand if the bike feels choppy and not plush then the re-
bound damping is too fast. A bit of trial and error is needed to get the exact setting.
Riders may choose to change their settings, while stationary, depending on the terrain
they are riding.

3.3: SET UP OF REAR SHOCK

Tools Required: Good Quality Shock Pump.
Please note that for the detailed instructions for servicing and all matters relating to
the rear shock, please refer to the manufacturers instructions accompanying this
manual.
The rear shock is pre-set with standard settings when you buy your Marin. Before
riding, you will need to fine adjust the sag setting on the rear shock. This is to ensure
it is set-up correctly for your own body weight, so the shock will perform as intended.
The correct 'sag' can be found using the sliding 'o' ring fitted to the shaft of the shock
piston. Slide the 'o' ring against the shock body. Then gently sit on the bike in your
normal riding position. Carefully dismount and measure the distance the 'o' ring has
moved away from the shock body. The optimum distance for the Marin QUAD 2 sys-
tem is between 25% and 30% displacement from the 'o' ring back up to the shock
