In the case of most suspension forks with coil springs a preload can be applied to the springs within tight limits by turning a knob at the top of the fork crown (a). If that is not possible and the desired negative suspension travel (“sag») cannot be set, the coil springs must be replaced by harder or softer models. The replacement is a job for the URBAN JUNGLE dealer.
When replacing any parts, be sure to only use parts that bear the appropriate mark and, to be on the safe side, original spare parts. Your URBAN JUNGLE dealer will be pleased to help you.
Always make a test ride over roads with various surfaces after each change to the settings (b).
Check afterwards the position of the rubber ring/cable tie. Its distance from the wiper is the maximum suspension travel that you have used (c). If the rubber o-ring/cable tie has moved a few millimetres only, your rear shock is too firm. Reduce the air pressure of air sprung forks or the initial spring tension of coil springs. If that brings no improvement, have the springs replaced.
If the rubber ring/cable tie has shifted over the entire length of the tube or if the fork audibly bottoms out and hits the top repeatedly when riding on bad roads, the setting of the springs is too soft. In the case of air-suspension forks the pressure must be increased. In the case of steel coils, have them replaced by your URBAN JUNGLE dealer.
WARNING
Suspension forks are designed in a way to absorb shocks. If the fork is too rigid and jammed, the terrain-induced shocks pass directly into the frame without any damping. The frame is normally not designed to withstand such undamped stresses. If your suspen- sion has a lockout mechanism, do not activate the lockout function when riding in rough terrain, but only when riding over smooth terrain (roads) and on field tracks.
The suspension fork should be set up and adjusted in a way that it does not reach the end of its travel, i.e. bottom out, unless in extreme cases. A spring rate which is too soft (air pressure is too low) 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 reaches bottom out. If the suspension fork frequently reaches bottom out, it will fail over time, and so will the frame.
