Blocking the Suspension Forks (Lockout)
Some suspension forks have a system to block suspension (lockout), which
is activated by a button or a lever. Depending on the manufacturer the operation
differs slightly.
With the lockout function activated, the stanchion tube does not move into the
lower leg. This function is recommended when riding uphill or out-of-the-saddle,
as the locking of the suspension avoids bobbing.
Some STEVENS bicycles have a remote lockout function. The lockout function
is activated easily with a button or a lever on the handlebar.
Make sure that the cable of the control unit on the handlebar is prop-
erly adjusted. The cable tension is adjusted by turning the adjusting bolt at the
control unit on the handlebar. Turn the adjusting bolt anticlockwise to increase
the cable tension and clockwise to reduce the cable tension. For more infor-
mation see the instructions of the component manufacturers on our website at
www.stevensbikes.de/manual
Always check a modified adjustment during a test ride.
Caution:
Do not actuate the lock-
out function when riding
over rough terrain, but
only when riding over
smooth terrain (roads,
field tracks).
Caution:
Do not ride with the
lockout function activat-
ed in challenging terrain
or when riding downhill.
Your suspension fork
could sustain damage.
Maintenance
Suspension forks are comparatively sophisticated components and require a
considerable amount of maintenance and care. This has led almost all suspension
fork manufacturers to establish service centres where customers can have their
forks thoroughly checked and overhauled at regular intervals. The following rou-
tines are essential for suspension fork maintenance.
• Whatever type of fork you have, Make sure that the sliding surfaces of the
upper fork tubes are absolutely clean. Clean the fork with water and a soft
sponge after every ride. Apply a thin layer of suspension fork or hydraulic oil on
the lower legs after cleaning.
• Make it a rule to check all bolted connections of your fork at regular intervals
with a torque wrench.
• If your fork has an elastomer filling, you should regularly clean and lubricate
the synthetic springs. Use non-corrosive resin-free grease only. Some fork
manufacturers provide special greases for fork maintenance. Observe the
manufacturer’s recommendations.
• Suspension forks with air springs have to be checked regularly for air pressure,
as the air escapes over time.
Use a suitable torque wrench and observe the manufacturer’s torque settings
when checking the bolted connections on your suspension fork!
Danger:
Do not turn any screws in the vague hope of adjusting them somehow. You
could release the fastening mechanism, thus causing a fall. All manu-
facturers normally mark adjustment devices with a scale or “+” and “-“
signs.
Note:
Check the functioning of the fork at regular intervals. Stand over your
STEVENS bicycle and press the fork downwards in jerks with your body
weight. The suspension fork must not bottom out. Observe the amount
of time it takes for the fork to rebound. It should take less time than the
compression. If you are in doubt about the proper functioning of your fork,
contact your STEVENS dealer.
Danger:
Before and after the
adjustment check the
tight fit of the bolted
connection in the centre
in the top area of the
stanchion tubes. The
adjusting mechanism
of almost all forks runs
through this bolt. It
could come loose during
adjustment!
Danger:
Suspension forks are of
sophisticated design.
The maintenance rou-
tines and above all the
disassembly of the fork
are jobs best left to your
STEVENS dealer.
