REBOUND DAMPING ADJUSTER KNOB

Rebound damping controls the speed at which the suspension returns 
to its extended position after being compressed by a bump. The rebound
damping on the Fox FLOAT RC and FLOAT R rear shocks can be tuned 
by turning the red adjuster knob, located on the shock body. To set the
rebound damping to a heavier position (for slower suspension return),
turn the adjuster knob clockwise when viewed from the front of the bike.
Conversely, to set the damping lighter (for quicker suspension return),
turn the knob counter-clockwise.

Rebound should be as fast as possible without kicking back and pushing
the rider off the saddle when riding the bike in rough terrain. If the re-
bound is too slow the suspension will not allow the wheel to follow the
changing terrain. Determining the proper rebound setting may take a
number of rides. During the first few rides adjust the damping and note
the different ride characteristics. You may want to change your rebound
setting for different riding conditions.

COMPRESSION DAMPING ADJUSTER 

Fox FLOAT RC rear shocks also have a compression adjuster which
changes the rate at which the shock compresses through the shock
stroke, stiffening the shock against small bumps. Determining the
proper compression setting is a matter of personal preference. During 
the first few rides adjust the two position lever to vary the compression
characteristics. Note that different trail conditions may favor different
compression settings.

WARNING FOR ALL CANNONDALE FRAMES:

WARNING: Inspect the frame carefully for damage after any crash, drop,
impact to the frame, or other harsh treatment. Riding a cracked frame
could lead to complete bicycle failure. Like other high-performance
structures, this frame should be inspected periodically for cracks. DO
NOT RIDE a bike with any crack, even a small one. See your authorized
Cannondale retailer or call 1-800-BIKE-USA. A crack will weaken the
frame and could lead to failure, with risk of serious injury or death to 
the rider.
