The suspension travel of the S
PINNER
fork is
45 mm.
The suspension fork should compress by 30%
with rider and luggage on the bike, which
corresponds to 12-15 mm (1/2").Attach a zip
tie to one of the stanchion tubes and slide it
down on the fork leg’s sealing. After getting
off your bike you can measure the sag be-
tween zip tie and sealing.
You set the recommended value by adjusting
the preload of the spring and by selecting the
correct spring stiffness
.
Every model has a
turning knob on the fork legs that allows a
simple adjustment of the preload.
The suspension fork S
PINNER
Grind has
springs only in the left fork leg.
By turning the knobs clockwise you increase
the preload, by turning them counter-
clockwise you decrease the preload.
The knob must turn easily. If a knob does not
turn any further you have reached the final
position. In that case turn back the knob in
the other direction for half a turn. Do not
turn the knob by force beyond the final posi-
tion since this will damage the plastic thread
inside.
Maintenance of the Spring fork S
PINNER
Clean and grease your suspension fork regu-
larly. Always use a high quality silicone or
Teflon lubricant. You can purchase special
lubricants for suspension forks at your local
specialist dealer.
Clean and lubricate the stanchion tubes every
four weeks and apply a thin film of grease or
special fork spray. If your suspension fork has
lubricating nipples at the back you should
insert a small amount of grease every four
weeks.
After six months at the latest the fork has to
be lubricated again. For that purpose open the
fork and dismount the parts as described in
the following paragraph. If you are in doubt
please have your bicycle mechanic do the
work.
If your suspension fork comes with a dust
boots please clean the lower and upper leg
and the seal under the dust boots every four
weeks. Otherwise, dirt and water can lead to
corrosion.
Attention!
The following instruc-
tions refer to SPINNER Grind2 suspension
forks. For other brands please see the in-
struction manual that comes with the
forks.
Danger!
Always check the correct
position of brakes and wheels after you
have worked on the suspension fork as
described in the respective chapters.
Check that the quick releases are tightly
closed.
