damage will reduce the life of the handlebar and
could lead to breakage.
■ seat Post
Remove from seat tube and remove from saddle.
Disassemble the head/saddle clamp assembly. Clean
and inspect all parts carefully for cracks.
Pay particular attention to the bolt (or bolts) that
clamp the saddle in place. If the bolt looks stretched,
bent or in any way damaged, replace it. Note that
these bolts have been known to be broken due to
fatigue when not properly tightened. They must be
tightened with a torque wrench.
The threads of the seat post bolts be greased before
reassembly.
Be sure the clamp assembly is clamped only to the
straight parallel part of the saddle rails.
■ seat Post lubrication

with carbon fiber components (Cannondale p/n KF115/).
■ saddle
While the saddle is off the seat post, clean and inspect
the rails carefully for cracks. Check the saddle rails to
the saddle body; make sure that the rails are firmly
attached.
■ Pedals
Remove both from the crankset. Clean and inspect
carefully for cracks. Pay particular attention to
the pedal axle. See clipless pedal manufacturer’s
instructions for information on cleat wear and
replacement.
■ Crankset
Remove both sides from the bottom bracket. Clean
and inspect all parts carefully for cracks. Examine
both inside and outside surfaces. Pay particular
attention to edges, shapes and changes of shape
that are a part of your particular crankset design. Also
check the area around the pedal mounting holes.
■ Wheels
Clean the wheels. Inspect the hub flange, where
the heads of the spokes are hooked (or otherwise
attached) to the hub flange, for cracks. Inspect the rim
where the spokes meet the rim. It is not uncommon
to see cracks form where the spokes meet the rim.

Brake track of Wheel Rim
The brake track is the surface of the rim where the
brake pads make contact. While not related to
fatigue, this surface can be worn out. We urge you
to inspect the brake tracks on your rims. They can
wear out quite quickly on a mountain bike used in
abrasive conditions. Many rims have brake track
wear indicators; please ask your retailer to show you
this feature.
Some brake pads are very aggressive and speed up
wear. If you see a noticeable amount of wear relative
to the nearby surface untouched by the brake pads,
speak to your retailer about possible replacement.
Severely worn brake tracks can lead to a broken
wheel.
WaRninG
do not Ride on a Rim that has Been WoRn
oUt!
If the wear indicator shows that the rim is worn
out, there is a danger that the rim could be
broken due to tire pressure and/or riding loads.
