2. DESCRIPTION

The damping unit controls the compression and rebound speed of the fork. During compression and rebound movements of
the suspension fork, oil is pressed through holes with adjustable cross section and through small spring plates (shims) which
allow more oil to pass through as the oil pressure increases (the faster the movement of the suspension fork, the higher the
oil pressure).
The damping unit is a closed system. The damping oil is separated from the air in the fork by a preloaded floating piston. This
prevents the oil from foaming and ensures a constant damping performance even on long, rough downhills.
2.1 COMPRESSION
The damping unit was rethought right from the start in the design of the F 535 suspension fork. A system was realized
that allows different damping characteristics over the stroke of the fork. In the first third of the travel, the suspension fork
responds extremely sensitively, with a firmer characteristic after the first third of the travel. This system provides maximum
traction and at the same time high control and feedback on the ground.
The low-speed compression (LSC) can be pre-adjusted in three steps «OPEN», «DRIVE» and «LOCK» for different terrain and
different demands.
OPEN
Full functionality and sensibility of the fork can be attained in the mode «OPEN». This setup is mostly suitable for downhills,
technical and rough uphills and comfortable rides on flat trails.
In order to meet the requirements of all riders, the low-speed compression can be set in "OPEN"mode with the setup tool
(Torx T10). The fork is very sensitive and comfortable when the compression damping is fully open (counterclockwise to the
stop). To use the full potential of the fork, we recommend using it with the compression damping fully open regardless of the
rider's weight and the bicycle. The compression damping can be incrementally increased for a less sensitive response.
DRIVE
The «DRIVE» mode sets the fork into a very firm mode. The fork moves, but is very firm. Movements from pedaling are mostly
eliminated. This setting is mostly advantageous for sporty and efficient pedaling on flat trails and uphills.
LOCK
The «LOCK» mode blocks the fork in fully extended position. This is mostly suitable for situations where no suspension is
needed (for example riding on the road or connecting trails). The lockout in the «LOCK» mode is hard and defined. A blow-off
valve protects rider and material from unexpected hits.
High speed compression (HSC)
The setup of the high-speed compression leads to a controlled feeling even on hard hits, jumps or steps. The high-speed
compression is pre-set and is not adjustable.
