Damping and Lockout
The damping is adjusted by valves inside. When the oil is forced through
these valves this slows down the speed with which the suspension fork
is extended or retracted and prevents the suspension "bouncing" after
hitting an obstacle.
b
For long uphill rides involving hard pedalling out of the saddle it is advis-
able to disable the damping, if the suspension fork has a lockout mech-
anism (a). For downhill rides on uneven ground the lockout mechanism
must be open.
Suspension forks
with an adjusting knob to slow down or accelerate the rebound move-
ment. Start the adjusting with a completely open damping ("-"). Ride
over an obstacle (e.g. a kerb) and turn the rebound damping in small
steps towards the "+" setting. You have found the proper rebound set-
ting when the suspension fork does not cycle more than once. Always
check a modified adjustment during a test ride.

If you do not trust the setting of the damping or if problems occur with
it, contact your WHEELER bicycle dealer or follow the corresponding
operating instructions of the suspension fork manufacturer, which you
can find enclosed on the CD.

The suspension fork should be set up and adjusted in a way
that it does not reach the end of its travel, i.e. bottoms out,
unless in extreme cases. A spring rate which is too soft
(or too low an air pressure) can usually be heard or felt as
a "clunk" type noise. This noise is caused by the sudden
complete compression of the suspension fork as it bottoms
outs. If the suspension fork frequently bottoms out, both the
fork and the frame will sustain damage over time.
Contact your WHEELER bicycle dealer and follow the re-
spective instructions in the fork manufacturer's operating
instructions, which you can find on the enclosed CD.

A too strong damping of the fork can result in a sluggish
rebound movement with a suspension fork that will not re-
cover when exposed to a quick series of impacts. danger of
an accident!
G
Do not turn any screws in the vague hope of adjusting them
somehow. You could release the fastening mechanism,
thus causing an accident. All manufacturers normally mark
the adjustment devices with a scale or with "+" signs (for
stronger damping/harder suspension) and with "-" signs.

When mounting a new front tyre, make sure there is enough
clearance between tyre and fork crown as the fork com-
presses entirely. The front wheel can get jammed. danger
of an accident!
A
Do not ride your bicycle, if the suspension fork often bot-
toms out. This could damage the suspension fork itself as
well as the frame.

Do not actuate the lockout function
rough terrain, but only when riding over smooth terrain
(such as roads or field tracks).

Maintenance
are fitted
The suspension forks
(f)
are components of sophisticated design that
require regular maintenance and care. This has led almost all suspen-
sion fork manufacturers to establish service centres where you can
have your forks thoroughly checked and overhauled at regular intervals
according to use, e.g. once a year. Be sure to have all the bolted con-
nections checked at regular intervals by your WHEELER bicycle dealer.
The following routines are essential for maintenance:
1. Make sure the sliding surfaces of the stanchion tubes are abso-
lutely clean.
2. Clean the fork, if soiled, with water and a soft sponge (g).
3. After washing your bicycle, spray the stanchion tubes with a little
grease spray
(h)
or apply a very thin film of hydraulic oil. Compress
the fork several times and wipe off excess lubricant with a clean
rag before you set off for your next ride.
4. Do not use a steam jet or aggressive cleaning agents for cleaning!
Ask your WHEELER bicycle dealer for suitable cleaning material.
