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.

TIGHTENING TORQUES
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!

ASYMMETRIC INTEGRATION (Ai) - REAR WHEEL
ABOUT
You must use rear wheels that are compatible
with the Cannondale Asymmetric Integration
(Ai) 6mm oset. OEM wheels built to this
specification are identified with “Ai” logo, shown
at right.
6mm OFFSET /
55mm CHAINLINE
The Ai rear hub is oset 6mm to the drive side.
This both aligns the cassette with the Ai frame’s
55mm chainline, and aligns the rim/tire with
frame’s centerline for correct tire clearance. (See
also, Maximum Tire Width in SPECIFICATIONS).
Ai wheels have equal spoke angles and tension
on both sides (non-dished wheel) which improves
wheel stiness, strength.
NOTICE
USE ONLY “Ai” OFFSET REAR WHEELS.
Incorrect wheel oset can damage your
frame.
Standard wheel assembled on this frame will
result in insucient tire clearance leading to
rubbing and serious frame damage. This kind
of damage is not covered by the Cannondale
Limited Warranty.
Building/Truing a Wheel
If you chose to build, or true the wheel, make
sure the 6mm oset is present.
Consult with your Cannondale Dealer if you
have any questions.

Carbon frames have a 46 mm I.D. bottom bracket bearing system press interface. The shell width is 83mm.
Maintenance
In general, you should inspect the condition of the bearings annually (at a minimum) or anytime the crankset
assembly is disassembled , serviced, or if a problem is indicated.
To inspect, when the crankset is removed, rotate the inner bearing race of both bearings; rotation should be
smooth, and quiet. Execesssive play, roughness or corrossion indicates a damaged bearing.
Removal
To avoid serious damage to the frame, it is important to remove bearing systems very carefully using proper
tools indicated by the manufacture’s service instructions. Make sure the bearings(cup or adpater parts) are
driven out squarely and evenly from inside the shell!!! Do not pry components from shell.
Replacement
PressFit BB30 bearings are not removable from the adapters or cup systems that are pressed into the frame
bottom bracket shell. Therefore, damaged bearings must be removed and replaced as new entire sets. Before
installing any new bearing units into the shell, thoroughly clean the inside surface of the bottom bracket shell
with a clean dry shop towel. Also, make sure both bearing units and the BB shell surfaces are clean and dry.
Do not apply grease to either.
Follow the manufacture’s instruction for assembly and installtion of the bearing system. Use a headset press
such as Park Tool HHP-2. See http://www.parktool.com/product/bearing-cup-press-HHP-2 Select appropriate
press and adapters to ensure that force is only applied to the cup and not the bearing inside. Press until the
both cup flanges are mated to the BB shell edge.
NOTICE
Consult with your Cannondale Dealer on the quality and compatibilty of any proposed replacement
component.
Make sure the PRESSFIT BB30 30 system is intended for use with with a 46 mm I.D. BB shell. Confirm
acutal part dimensions with a micrometer.
Do not use chemical solvents to clean. Do not remove frame material or use surfacing tools on bottom
bracket shell.
Frame damage, caused by improper components, component installation or removal is not covered by your
warranty.

133422.PDF
The bottom bracket shell is compatible with the BB30 Standard. See http://www.bb30standard.com/ .
Maintenance
Inspect bearing condition annually (at a minimum) and anytime the crankset assembly is disassembled or
serviced. With the crankset removed, rotate the inner bearing race of both bearings; rotation should be
smooth. No play or movement inside the shell. If the bearing is damaged, replace both bearings with new
ones.
Bearing Removal
Remove the old bearings with the bearing removal tool KT011/.
Bearing Installation
To install bearings, use a headset press and Cannondale tool KT010/. Clean inside of shell apply a high-quality
bicycle bearing grease to the inside surface. Press bearing one at a time. Press each bearing until seated.
Following installation, apply a light coating of a high-quality bicycle bearing grease to both sides of each
bearing to help repel moisture.
Do not re-use removed bearings. Install both bearings as a new set.
NOTICE
BEARINGS - Frequent or routine renewal of undamaged bearings is not recommended. Repeated removal
and reinstallation can damage the inside BB shell surfaces resulting in poor bearing fit. Do not face, mill
or machine the bottom bracket shell for any reason. Doing so can result in serious damage and possibly a
ruined bike frame.
DO NOT CUT, FACE, OR USE ABRASIVES TO CLEAN THE INSIDE IF THE BB SHELL.
We strongly recommend that these procedures be performed by an Authorized Cannondale Dealer.
Damage caused by improper installation/removal is not covered under your warranty.

Set-Up
1. Set the air pressure according to your body
weight. Follow the shock manufacturer’s
instruction for pressurizing the shock.
2. Slide the O-ring against the shock wiper
seal.
3. Sit on the bike in a normal riding position
with your hands on the handlebar and
feet on the pedals so that your weight
compresses the rear shock.
4. Measure the SAG. Adjust the air pressure
in the shock to achieve the correct SAG
measurement.
Add air to decrease sag.
Release air to increase sag.
Recommended Sag 25% - 12mm
WARNING
SELECT ONLY COMPATIBLE SHOCKS AND FORKS
FOR YOUR BIKE. DO NOT MODIFY YOUR BIKE IN
ANY WAY TO MOUNT ONE. HAVE YOUR SHOCK
OR FORK INSTALLED BY
A PROFESSIONAL BIKE MECHANIC
• Riding with the wrong rear shock can
damage the frame. You could have a
serious accident. Make sure the total
travel, eye-to-eye length, and stroke
length of the rear shock you select
meet the SPECIFICATIONS listed in this
manual.
• When selecting dierent shocks or
forks for your bike, make sure that the
shock or fork you select is compatible
with your bike’s design and how you will
use your bike.
