WHEEL BUILDING AND TRUING
A special tool has been developed to mount GEMINI wheels in truing stands. Tool parts are: (1) Shaft, (2) O-ring, (3) Cap.
SUSPENSION
Your model may have any one of several different front forks or rear shocks supplied to Cannondale by various
manufacturers. Please read the manufacturer's owner's manual or instructions provided before attempting any set-up or
adjustment.
SAG & PRELOAD ADJUSTMENT
Sag is the distance the bike suspension compresses with a rider wearing all gear is mounted in a normal riding position on
flat ground. The recommended sag for the bike is designed to maximize the bike's suspension travel and it is usually
specified as a percentage (%) of the fork or shock's total travel. See the Specifications section in this manual for the
recommended sag. Maintaining the recommended sag in both the front and rear suspension helps assure that the fork and
shock travel operates normally without the excessive top-out or bottom-out that can lead to difficult handling or damage.
Small adjustments to sag are performed by adjusting preload of the shock or fork. This is done by adding or removing
spring shims, adjusting the installed length of the spring with a preload adjusting ring, or with air springs, changing pressure
settings. Larger adjustments to sag are require changing the installed springs in the fork or shock. Changing a the spring
may be a simple task or very complex depending on the design of the fork or shock. In general: increasing preload
decreases sag, decreasing preload increases sag. Finding a suitable sag setting within the suspension fork or rear shock
range is a matter of personal preference taking the body weight and how you ride into consideration.
SELECTING REAR SHOCKS FOR YOUR GEMINI
Please consult the technical specification section of this manual before fitting a rear shock on your Gemini.

CAUTION: Consult the fork or shock manufacturer's manual for recommend sag and adjustments procedures.
Incorrect sag can contribute to excessive shock to top-out or bottom-out. If the recommended sag can not be achieved
by preload changes, a different spring (softer or stiffer) may be necessary. Consult the manufacturer's manual for
details
WARNING: Riding with the wrong rear shock can damage the frame. You could have a serious
accident.
Make sure that the total travel, eyelet-to-eyelet length, and stroke length of the rear shock you
select meets the specifications listed in this manual.
Also, make sure the physical shape (including any reservoir and adjustments features) will not
cause interference with or contact the frame, frame mounting points, or the swingarm tat any
point in the full suspension travel.
Consult with your Cannondale Dealer on the right rear shocks to use.
