Do not use a steam jet or aggressive cleaning agents! Ask your bicycle

dealer for an appropriate lubricant.

If your fork has an elastomer filling, you should regularly clean and lubri-

cate the synthetic springs with a non-corrosive resin-free grease. Some fork

manufacturers provide special greases for fork maintenance. Be sure to fol-

low the recommendations of the manufacturers. Forks with air springs have

to be checked regularly for air pressure, as the air escapes over time .

Suspension forks are components of sophisticated design that

require regular maintenance and care. This has led almost all

suspension fork manufacturers to establish service centres

where you can have your fork thoroughly checked and over-

hauled at regular intervals according to use, e.g. once a year. Be

sure to have all bolted connections checked at regular intervals

by your bicycle dealer.

Suspension forks are constantly being sprayed with water and

dirt from the front wheel. Clean them with lots of water after

every ride.

Suspension elements are of sophisticated design. The mainte-

nance routines and above all the disassembly of the suspension

elements are jobs best left to your bicycle dealer.

Be sure to have your suspension fork checked by a service cen-

tre of the fork manufacturer once a year at least.

Full-suspension bicycles are equipped not only with a suspension fork but

also with movable rear stays which are sprung and damped by a shock

absorber . This feature gives you better control of your bicycle when rid-

ing cross-country or on rough road surfaces. It noticeably reduces the strain

on you and your bicycle caused by the mechanical shocks from the terrain.

With rear shocks this normally works with an air spring element or, less

frequently, with coil springs. Damping is usually controlled by the use of oil.

Depending on the system the rear shock has one or more bearing axles with

at least two bearings each.

For more information see the suspension glossary heading this

chapter.

Full-suspension bicycles sag a little when you sit on the saddle. This causes

the saddle to tilt a little backwards, an effect which can be compensated by

adjusting the position of the saddle. If you have trouble sitting, try lowering

the nose of the saddle a little compared to your usual position.

Full-suspension bicycles have a greater ground clearance than

bicycles without rear suspension. With a properly adjusted sad-

dle height you will not be able to reach the floor with your feet.

Set the saddle a little lower to begin with and practise getting

on and off the saddle.

In order to work optimally, the rear shock has to be adjusted to the weight of

the rider and its intended purpose. Be sure to have this adjustment carried

out by your bicycle dealer before delivery.

With an air spring element you have to inflate the rear shock before your first

ride . The rear shock adjustment depends on the rider’s weight and the

sitting posture.

Please bear in mind that the rear swing arm of the rear shock should sag a

little under the rider’s weight. When the rear wheel passes through a depres-

sion in the ground the spring can then extend and the suspension mecha-

nism will smooth out the uneven surface. If the selected air pressure is too

high, this effect is lost because the wheel will already be fully extended. This

means the loss of an important feature affecting both safety and comfort.

To aid measurement you can use the rubber o-ring often available on the

shock’s shaft, which slides further down the shaft as the rider gets on the

bicycle or slip a cable tie onto the thinner tube of the rear shock so that it

can still shift easily along the tube.

Cross-country and marathon racers usually run less sag than downhillers or

more comfort loving freeriders. For cross-country and marathon riding the

rear shock should yield by about 10-25 % of its total travel , for enduro

and freeriding by about 20-40 % .

To measure the maximum shock travel release all the air pressure from the

rear shock. Compress the rear shock completely. Then inflate the shock

absorber to the recommended air pressure and measure the distance be-

tween the rubber o-ring/cable tie and the upper edge of the shock body .

In the case of oil/air sprung rear shocks, the spring rate is adjusted by the air

pressure in the damper. The pressure must be checked at regular intervals

with a special shock pump which is normally made available by the rear

shock manufacturer. Please follow the recommendations of the manufac-

turer.

Ride your bicycle on different kinds of surface and check afterwards the

travel of the rubber o-ring/cable tie. The difference is the rear shock’s travel

you have used. 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 rear

shocks or the initial spring tension of coil springs. If your rear shock is still too

firm, have the springs replaced.
