2. AIR FORK
The suspension hardness of air forks is set by inflating the air in the air chamber of the fork. The air
inflation valve is located at the top of the left fork leg.
The pressure in the fork needs to be adjusted according to your operating weight (your weight with
clothes and other equipment you will use during the ride).
ADJUSTING FORK HARDNESS WITH SAG
SAG indicates the immersion of the inner fork legs into the lower legs. This value is given as
a percentage of the total fork lift. On one of the legs there is a rubber ring, usually of a distinctive
colour, slide this ring against the seals on the top of the lower legs. Load the e-bike freely (slowly sit on
the e-bike and slowly stand up from the saddle so that your feet stay on the pedals, do not squeeze,
or load the fork in any other way), dismount the e-bike carefully and measure the depth of immersion.
The SAG should be set according to the discipline you are riding:
- for better pedalling efficiency choose a harder setting (15 % – 20 % SAG)
- for better absorption of large uneven terrain, choose a softer setting (20 % – 25 % SAG)
For some fork models, the recommended pressure values depending on weight are indicated directly
on the forks.
NOTICE
The fork is set up by the manufacturer and checked by your dealer. A special high-pressure pump for
air forks with a pressure gauge is required to inflate the fork. Adjusting and inflating the fork requires
skill and the right tools, which is why we recommend you contact a professional bike shop.
FORK SUSPENSION LOCKOUT
Some forks have a hydraulic fork suspension lock system. The fork lock allows you to reduce fork
wobble when pedalling and thus achieve more efficient pedalling, especially when riding uphill or
sprinting.
The adjustment unit for locking the fork suspension is located at the top of the right fork leg. The
lockout is controlled by a lever (marked Lockout). Turning clockwise will lock the fork suspension,
turning anti-clockwise will unlock the suspension and the fork will operate in normal mode.
IMPORTANT NOTICE
The fork suspension lock is mainly designed for riding on less demanding terrain. When riding on
rough terrain, the fork must be unlocked, otherwise the fork locking system may be damaged!
FORK REBOUND DAMPING
The Rebound fork rebound damping adjuster sets the speed at which the fork returns to its original
position when depressed. The control for the Rebound is located at the bottom of the right fork leg.
Turning the adjustment unit clockwise (view from the bottom of the fork) slows the rate of return to
the original position (marked “+” on the fork). Turning counter-clockwise increases the speed (marked
“-” on the fork). Too slow rebound damping can cause the fork to “not keep up” with uneven terrain;
conversely, too fast rebound causes the fork to return too quickly, thus defeating the purpose of the
rebound damping function.
FORK MAINTENANCE
CLEANING / LUBRICATION - regular maintenance, especially of the friction surfaces between the inner
and outer fork legs, is important for proper fork operation. Dust cap and seal, which prevent dirt
from reaching the friction surfaces, must not be broken and must protect the friction surface around
the entire perimeter. Keep the sliding surfaces of the inner legs clean, wipe off any dust or moisture
with a soft cloth and re-grease after each ride. Use a detergent solution and a soft brush to clean the
outside of the fork. When cleaning the fork, make sure that no water enters the gap between the
inner and outer legs. Never use high-pressure cleaners for cleaning! Moisture and dirt inside the fork
adversely affect its operation, dirt in the fork causes more friction between the bushings and the inner
fork legs, thus reducing the service life of the individual fork parts.
Observe the following instructions to maintain perfect fork operation:
• After each ride, clean the inner fork legs, dust caps and inner fork leg seals of debris such as dust,
moisture or mud.
