SAFETY WARNINGS
The rear shock is an important part of your bike.
Before installing and using your new rear shock,
carefully read this owner’s manual to learn the correct
installation and adjustment procedures of the shock.
Improperly installed and/or adjusted shocks can
cause serious harm or death and may severely
damage your bike.
A broken or malfunctioning shock may cause loss
of vehicle control and result in SERIOUS INJURY
OR DEATH. If the shock ever loses oil, air or makes
unusual noises, stop riding and have the shock
inspected by a Cane Creek Authorized Suspension
Service Center or call the Cane Creek Customer
Service Team.
Modification, improper service or use of aftermar-
ket replacement parts voids the warranty and may
cause the shock to malfunction, resulting in loss of
vehicle control and SERIOUS INJURY OR DEATH.
Do not modify your bike frame or shock. Use only
genuine Cane Creek Double Barrel parts.
Follow service maintenance recommendations.
Shock service should be performed by Cane Creek
Cycling Components or a Cane Creek Authorized
Suspension Service Center. Visit www.canecreek.
com or contact us at 800-234-2725 to locate a
Cane Creek Authorized Suspension Service Center.

Cane Creek rear shocks contain a nitrogen charge
in the reservoir. Opening a nitrogen pressurized
shock is dangerous and can result in SERIOUS
INJURY OR DEATH. The shock should only be
opened by a Cane Creek Authorized Suspension
Service Center.
Cane Creek rear shocks are manufactured ex-
clusively for the bike model for which they are
ordered. Switching units between different bikes
may not only decrease the shocks performance but
might also cause damage to the bike and can result
in SERIOUS INJURY OR DEATH. Always contact
Cane Creek or Cane Creek Authorized Suspen-
sion Service Center to verify compatibility before
switching a shock from one bike to another.
Any improper servicing procedure with a Cane
Creek shock with “stuck down” condition can
lead to SERIOUS INJURY OR DEATH. Contact
Cane Creek or an Authorized Suspension Service
Center for repair.

SAFETY WARNINGS
Never attempt to pull apart, open, disassemble or
service a Cane Creek shock that is in a stuck down
position. Stuck down is a result of a failure of the
dynamic air seal (located between the positive and
negative air chambers within the shock sleeve) that
causes the negative chamber to retain a higher air
pressure than the positive chamber. To determine if
a shock is stuck down:
a. Deflate the shock completely.
b. If the shock body retracts into the air sleeve
to a nearly bottomed-out position after the
air is released from the positive air chamber,
attach an air pump and inflate the shock to
200 psi (13.8 bar).
c. If the shock does not fully extend, it is in a
stuck down condition.
WARNING
When backing-out your Low Speed
adjuster, BE CAREFUL NOT TO
OVER-TORQUE. When you feel
resistance - STOP. Turning further
WILL DAMAGE YOUR SHOCK.

AIR SHOCK INSTALLATION
Before your fi rst ride it is important to verify
fi tment by following the steps below.

SAG ADJUSTMENT
2 Dressed in full riding gear, mount your
bicycle and assume your normal riding
position. Dismount and measure the
distance the O-ring has moved. This
measurement is your sag. You can
fi nd recommended sag on the Base
Tune card provided with your bike or
at: canecreek.com/products/suspension.
1 Infl ate shock to starting pressure;
20 psi less than your weight (with
gear) is a good starting point.

AIR/DBAIR CS/

INLINE
Sag = Distance from air can to O-ring.

15
SAG ADJUSTMENT
3 Cycle the shock to charge the
negative air spring. Recheck sag,
adjust air and repeat until you
have the desired measurement.

16
As an additional tuning tool, the spring rate of your
air shock can be adjusted using the included air
volume spacers (see Anatomy chart on pages 8-11).
This is independent of the air pressure adjust-
ment. Air pressure should be used to achieve the
correct sag value (see Base Tune, Tuning Field
Guide, or canecreek.com). If the bike bottoms out
harshly or too frequently, an air volume spacer
can control how progressive the shock is.
More air volume spacers will provide a more pro-
gressive air spring. A more progressive spring will
prevent harsh bottom-outs, since the spring will be
“stiffer” as the bike gets closer to full travel.
Fewer air volume spacers will provide a more
linear (less progressive) air spring. A less progres-
sive air spring will make it easier to use the full
travel of the bike.
AIR VOLUME ADJUSTMENT
Tuning Air Volume

17
As air volume spacers are added to make the air
spring more progressive, adding additional High
Speed Rebound (HSR) will keep the bike from
“bucking”. A good rule of thumb is 1/4 turn of ad-
ditional HSR for each large volume spacer added.
AIR VOLUME ADJUSTMENT
Do not over torque the adjuster past its limit stop.
You won’t feel a hard stop, you will feel resistance.
When you feel resistance - STOP.
