SAFETY INFORMATION
IMPORTANT COMPOSITES MESSAGE
WARNING
Your bike (frame and components) is made from
composite materials also known as“carbon ber.”
All riders must understand a fundamental reality
of composites. Composite materials constructed of
carbon bers are strong and light, but when crashed or
overloaded, carbon bers do not bend, they break.
For your safety, as you own and use the bike, you must
follow proper service, maintenance, and inspection of all
the composites (frame, stem, fork, handlebar, seat post,
etc.) Ask your Cannondale Dealer for help.
We urge you to read PART II, Section D.“Inspect For Safety”
in your Cannondale Bicycle Owner’s Manual BEFORE you
ride.
YOU CAN BE SEVERELY INJURED, PARALYZED OR
KILLED IN AN ACCIDENT IF YOU IGNORE THIS
MESSAGE.
BICYCLE REPAIR / WORK STANDS
The clamping jaws of a bike stand can generate a crushing
force strong enough to seriously damage your frame.
NOTICE
Never place your bike in a bike stand by clamping the frame.
Place your bike in a stand by extending the seat post and
positioning the stand clamp on the extended seat post. Don’t
extend beyond the MINIMUM INSERT line marked on the seat
post.
Since your carbon seat post can also be damaged by clamping
force, adjust the stand clamp for the minimum clamping force
needed to secure the bike.
Also, before clamping, clean the post and protect the seat post
nish with a rag.
INSPECTION & CRASH DAMAGE OF
CARBON FRAMES/FORKS
WARNING
AFTER A CRASH OR IMPACT:
Inspect frame carefully for damage (See PART II, Section
D. Inspect For Safety in your Cannondale Bicycle Owner’s
Manual. )
Do not ride your bike if you see any sign of damage, such
as broken, splintered, or delaminated carbon ber.
ANY OF THE FOLLOWING MAY INDICATE A
DELAMINATION OR DAMAGE:
■An unusual or strange feel to the frame
■Carbon which has a soft feel or altered shape
■Creaking or other unexplained noises,
■Visible cracks, a white or milky color present in
carbon ber section
Continuing to ride a damaged frame increases the
chances of frame failure, with the possibility of
injury or death of the rider.

INTENDED USE
All models are intended for Condition 3 Cross-Country,
Marathon) riding. Condition 43 symbol shown in next gure.
For riding on
unimproved
trails with
small obstacles
CONDITION 3
Bikes designed for riding Conditions 1 and 2, plus rough
trails, small obstacles, and smooth technical areas, including
areas where momentary loss of tire contact with the ground
may occur. NOT jumping. All mountain bikes without rear
suspension are Condition 3, and so are some lightweight rear
suspension models.
INTENDED
For cross-country riding and racing which ranges from mild
to agressive over intermediate terrain (e.g., hilly with small
obstacles like roots, rocks, loose surfaces and hard pack and
depressions). There are no large“sick drop”or drop os,
jumps or launches (wooden structures, dirt embankments)
requiring long suspension travel or heavy duty components.
Cross-country and marathon equipment (tires, shocks, frames,
drive trains) are light-weight, favoring nimble speed over
brute force. Suspension travel is relatively short since the bike
is intended to move quickly on the ground and not spend time
in the air landing hard and hammering through things.
NOT INTENDED
For use in extreme forms of jumping/riding such as hardcore
mountain, Freeriding, Downhill, North Shore, Dirt Jumping,
Hucking etc.
TRADE OFF
Cross-Country bikes are lighter, faster to ride uphill, and more
nimble than All-Mountain bikes. Cross-Country and Marathon
bikes trade o some ruggedness for pedaling eciency and
uphill speed.

MAXIMUM FORK LENGTH
Maximum Fork Length is an important frame safety testing
specication. You must observe the measurement when
installing headset parts, headset adapters, installing and
adjusting a fork, and selecting replacement forks. In this
manual, the number is also listed in the GEOMETRY/
SPECIFICATIONS.
HEADTUBE
HEADSET
PARTS or
ADAPTERS
AXLE
MAXIMUM FORK LENGTH
HOWTO MEASURE: 1. Install headset and fork. 2. Extend
fork and measure the distance from the bottom of the head
tube to the center of the wheel axle. Do not measure from
the bottom of headset bearing cups or head tube adapters.
The measurement MUST be taken from the bottom of the
head tube!!
WARNING
DO NOT EXCEED MAXIMUM FORK LENGTH
Exceeding the MAXIMUM FORK LENGTH limit can overload
the frame causing it to fail (break) while riding.
YOUCAN BE SEVERELYINJURED, PARALYZEDOR KILLED
IN AN ACCIDENT IF YOU IGNORE THIS WARNING.
TIRE SIZE
WARNING
OBSERVE THE “MAXIMUM TIRE WIDTH” FOR YOUR
BIKE FOUND IN THE GEOMETRY/ SPECIFICATIONS
SECTION OF THIS SUPPLEMENT.
Mounting the wrong size tires can result in the tires
hitting the fork or frame when riding. If this happens,
you can lose control of your bike and you can be thrown
o, a moving tire can be stopped because it touches the
fork or frame.
Do not mount oversized tires, ones that rub or hit the fork
or frame, ones that result in too little clearance, or ones
that can hit the fork or frame when the suspension is fully
compressed or when riding.
Take care that the tires you select are compatible with
your bike’s fork or frame design. Also, be sure to follow the
manufacturer’s recommendations of your front fork and
rear shocks.
When you are considering tires for your bike consider...
The actual measured size of a tire may be dierent than
its sidewall marking. Each time you mount a new tire,
take the time to inspect the actual clearance between the
rotating tire and all parts of the frame. The U.S. Consumer
Product Safety Commission (CPSC) requires at least
1/16”(1.6 mm) tire clearance from any part of the bike.
Allowing for lateral rim ex and a wheel or rim that is out-
of-true will likely mean choosing a rear tire that provides
even more clearance than the CPSC recommends.
ASK YOUR CANNONDALE DEALER FOR THE RIGHT
TIRES FOR YOUR BIKE AND ITS PARTICULAR
COMPONENTS!
YOU CAN BE SEVERELY INJURED, PARALYZED OR
KILLED IN AN ACCIDENT IF YOU IGNORE THIS
WARNING.

FLASH CARBON SEAT POST
MINIMUM SEAT POST INSERT DEPTH
For carbon frames, the seat post must be inserted a minimum
of 90 mm or 3.5 inches
90 mm
WARNING
MAKE SURE AT LEAST 90 mm OF THE SEAT POST IS
INSERTED INTO THE FRAME AT ALL TIMES. Failure to
insert the seat post correctly can place a very high stress on
the seat tube top tube junction causing the frame to break
while riding.
If your seat post isd eat post. Measure 90 mm from the
bottom of the seat post. Use a permanent marker to mark
the post at 90 mm. When adjusting the seat post height in
the seat tube, never adjust the seat post so that the line you
mark is above the top edge of the seat tube.
YOU MUST ALSO BE AWARE THAT bicycle seat posts are
permanently marked by the manufacturer with a“MINIMUM
INSERT” line on the seat post itself. You must not rely on this
marking as an indication of the proper MINIMUM SEAT POST
INSERTION DEPTH.
YOU CAN BE SEVERELY INJURED, PARALYZED OR KILLED
IN AN ACCIDENT IF YOU IGNORE THIS WARNING.
Installation
1. Always clean the inside of the seat tube with a dry clean
shop towel.
2. Apply a generous amount carbon gel to the inside of the
clean seat tube and to the seat post. A small nylon brush
works well for spreading inside the seat tube.
3. Apply small amount of bicycle bearing grease to the area
under the binder on the seat tube. Reinstall the seat
binder. Be sure to align the binder pin with the seat
tube slot.

4. Insert the seat post, set saddle height, and tighten the
binder bolt to 5 Nm, 44 In Lbs.
NOTICE
NEVER USE SOLVENTS OR SPRAY CLEANERS.
DON’T USE GREASE; ALWAYS USE CARBON GEL. Cannondale
in kit KF115/ is a small quantity, enough for two or three
applications.
NEVER FORCE THE SEAT POST INTO THE FRAME. Stop
inserting the seat post before SAVE feature. See “MAX.
INSERT” on page 7.
ALWAYS USE A TORQUE WRENCH.
TIP: When tightening the seat binder, also check the specied
tightening torques of the saddle to seat post clamp bolts.
TIP: Its a good idea to periodically remove the binder bolt, from the
binder, clean it threads and lightly grease the threads.
Cutting the Seat Post
When cutting the seat post
1. Make a straight cut; use a cutting guide such as ParkTool
SG-7 and a carbon specic saw blade. Lightly round and
smooth the nished cut with ne sandpaper.
2. Re-mark the MINIMUM INSERT line 90 mm up from the
bottom of the cut seat post. Mark the seat post without
scoring, scratching or otherwise damaging the surface of
the seat post. Use a thin decal (automotive pin striping)
or a paint marker.
NOTE: U.S. Consumer Product Safety Commission (CPSC)
bicycle regulations require minimum seat post insertion
be marked on the seat post.
WARNING
If the seat post requires cutting, have it done by a
professional bike mechanic with experience cutting high-
performance carbon components.
YOU CAN BE SEVERELY INJURED, PARALYZED OR
KILLED IF YOUR IGNORE THIS WARNING.
