Description
2.1
Spring: NCS (Negative Coil Spring)
DT Swiss forks with NCS (Negative Coil Spring) technology use an air spring consisting of a positive air chamber
and a negative steel spring. The negative spring counteracts the pressure inside the positive air chamber and
thus improves the response characteristics drastically. The negative spring is designed to achieve a perfect
spring rate and therefore performance, irrespective of the rider‘s weight.
2.2
Damping: O.D.L (OPEN, DRIVE, LOCK)
The O.D.L 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.
The oil gets in contact with the inner wall of the stanchion. This leads to a better heat dissipation compared to
a completely closed cartridge.
2.2.1
Low-Speed Compression (LSC)
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.
To meet the needs of all riders, the low-speed compression (LSC) can be adjusted in the mode «OPEN» with the
blue compression adjusting wheel.
•
When the compression is completely opened (compression adjusting wheel is turned anti-clockwise until
stop), the fork is very sensible and comfortable. This is mostly suitable for the comfort-oriented rider,
who is riding in easy terrain.
•
When the compression is increased (turning the compression adjusting wheel clockwise), the fork gets
more firm and sporty. The sporty rider with an active riding style gets more feedback from the ground.
This setting is mostly advantageous on technical, demanding trails.
Additionally, the change of the viscosity in cold conditions can be compensated by adjusting the com-
pression.
•
When the compression is completely closed, the setting mostly meets the setup of the «DRIVE» mode.
DRIVE
The «DRIVE» mode sets the fork into a very firm mode. 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.
2.2.2
High-Speed Compression (HSC)
The firm 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.
