Important Composites
Message

WARNING

Your bike (frame and components) is made from
composite materials also known as “carbon
fiber.”

All riders must understand a fundamental reality
of composites. Composite materials constructed
of carbon fibers are strong and light, but when
crashed or overloaded, carbon fibers 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.

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 fiber.

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 fiber section

CONTINUING TO RIDE A DAMAGED FRAME
INCREASES THE CHANCES OF FRAME
FAILURE, WITH THE POSSIBILITY OF INJURY
OR DEATH OF THE RIDER.

Correct tightening torque for the fasteners (bolts, screws, nuts) on your bicycle is very important to your
safety, the durability and performance of your bicycle. We urge you to have your Dealer correctly torque all
fasteners using a torque wrench. If you decide to tighten fasteners yourself always use a good torque wrench!

JEKYLL FRAMES

BallisTec Carbon Technology

Light, sti and ultra-tough carbon fiber construction.

New, High-Strength, High-Impact Carbon construction. Ultra high-strength fibers developed by the Japanese
Military for ballistic armor, and impact-resistant hot melt resins are used as the primary structural materials
of the frame, while high modulus carbon fibers are used to strategically enhance stiness. Lighter and stier
than aluminum, stronger and more durable than steel, BallisTec Carbon can shake o rock strikes and impacts
that would cripple the competition and their carbon “shields”.

SmartFormed Alloy

The alloy versions use SmartFormed, septuple-butted, heat-treated 6000 series aluminum. The down tube
alone has seven dierent wall thicknesses, created by butting the tube along its length, then mechanically
shaping the tube, then hydro forming it into the final shape. Labor intensive and dicult, it shows
Cannondale’s continued mastery of the aluminum arts.

Integrated Headtube

Both frame types feature integrated Si bearing cups. In alloy frames, the cups are machined within the head
tube. In carbon models, cups are bonded within the head tube. Cannondale Headshok System Integration
bearings are accepted directly into both type. For 1.5” and 1 1/8” adapter headsets, see Replacement Parts.

NOTICE

Do not face, surface, or cut the head tube bearing cups.
When removing adapters, bearings, or cup from, extra
care must be used so that the tool used to drive out the
bearing is not located on any part a bonded cup.
