Low-speed compression (A) and low-speed compression lock out
D
A
lever (B)
The low-speed compression (A) affects the shock's compression
performance over small bumps or through the beginning of the travel.
C
It might be useful to harden the low-speed compression (by turning
the knob clockwise) on rolling terrain with big compressions and
pedaling sections.
It might be useful to soften the low-speed compression (by turning the
B
knob counter-clockwise) on steep gradients.
The lock out lever (B) acts on the low-speed compression and affects
the shock's threshold. It is useful to lock it out on pedaling sections and
uphills to maintain the bike's balance.
High-speed compression (C)
The high-speed compression acts mainly on harsh hits (jump landings,
rough sections). It should be soft enough to get all the travel without
bottoming-out. If, on a given track, you bottom-out frequently, harden
the high-speed compression by turning the knob clockwise. However,
don't get hung up on bottoming-out if it only happens once or twice
during your run. You risk setting your shock for 3% of the course and losing efficiency on the other 97%.
If your shock doesn't get full travel, soften the high-speed compression by turning the knob counter-
clockwise.
Rebound (D)
The main factor in adjusting the rebound is the position of the bike. A bike shouldn't be "sunken down" all
the time, although the back does need to be fairly low. Adjusting the rebound will allow you to maintain
this balance.
If you feel like the back of the bike is pushing you forward on a slope or when braking, slow down the
rebound (turn the knob clockwise). It can be useful to go along with this adjustment (especially if the
problem persists) by slightly soften the low-speed compression.
However, if the bike seems too low at the back and/or the front end has a tendency to drift offline, speed
up the rebound.
Lockout lever repositioning:
It's possible for your comfort and to fit all the bikes to move the initial position of the lockout lever.
Please unscrew the screw (1), pull the lever and place it at the desired position. Then put back the screw
and tighten until contact.
