 Safety Information

Important Composites Message
WARNING

Your bike (frame and components) is made from composite materials also known as “carbon fiber.”
All riders must understand the 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 warning.
WARNING
After A Crash Or Impact:
Inspect the 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 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 the 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.
Intended Use

The intended use of all models is ASTM CONDITION 3, Cross-Country.
WARNING
Please read your Cannondale Bicycle Owner’s Manual for more information about Intended Use and Conditions 1-5.
Servicing
WARNING
This supplement may include procedures beyond the scope of general mechanical aptitude.
Special tools, skills, and knowledge may be required. Improper mechanical work increases the risk of an accident. Any bicycle accident has a risk of serious injury, paralysis or death.
To minimize risk we strongly recommend that owners always have mechanical work done by an Authorized Cannondale Dealer.
Tightening Torques
Correct tightening torque for the fasteners (bolts, screws, nuts) on your bicycle is very important to your safety. Correct tightening torque for the fasteners is also important for 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 torque fasteners yourself always use a torque wrench. Find Tightening Torque Information :
The wide range of bicycle models and components used means that a listing of tightening torque would be out of date by the time it was published. Many fasteners should be installed with a thread-locking adhesive such as Loctite®.
To determine the correct tightening torque and any adhesive application for a fastener we ask you to check:
Many components are marked. On-product marking is becoming common. ·Torque specs in the component manufacturers instructions shipped with your bicycle. Torque specs are listed on the websites of component manufacturers.  With your dealer. Dealers have access to current data and have experience with the correct torque for most fasteners.
Maximum Fork Length
Maximum Fork Length is an important frame safety testing specification for front suspension mountain bikes. You must observe the measurement when installing headset parts, and headset adapters, installing and adjusting a fork, and selecting replacement forks.

WARNING
You must select a replacement fork not only based on head tube diameter but the critical factor of frame maximum fork length.
Do not exceed maximum fork length. Exceeding the MAXIMUM FORK LENGTH limit can overload the frame causing it to break while riding.
Your retailer MUST follow and observe this specification for your bike. For Maximum Fork Length specifications for Cannondale bicycles, see www.cannondale.com.
You can be severely injured, paralyzed or killed in an accident if you ignore this warning.
Tire Size x Maximum Width
WARNING
Observe the Tire Size x Maximum Width for your bike found in the “Specifications” page of this manual.
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 off. A  moving tire can be stopped because it touches the fork or frame.
Do not mount tires that are larger than the maximum recommended size. Such tires could contact the fork, frame, saddle, seat post, or seat binder when the suspension is fully compressed or while riding. Only select tires that are compatible with your bike’s fork and frame design. Also, be sure to follow the manufacturer’s recommendations for your front fork and rear shock.
When you are considering tires for your bike consider…
The actual measured size of a tire may be different 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 flex 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 authorized brand retailer 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.
Serial Number
The serial number is located on the bottom bracket. It is a 7-character barcode (1). Use this serial number to register your bike.
To register your bike: go to the Product Registration section of our website at www.cannondale.com

Minimum Seat Post Insert – Frame
WARNING
Keep the frame’s minimum seat post insertion length inserted into the frame at all times. The length is found in the “Specifications” table in this manual.
To mark the seat post with a frame minimum seat post-insertion mark:

1. Remove the seat post.
2. Measure the length of the specification up from the bottom of the seat post.
3. Make a permanent ink line mark on the seat post.
   If you have questions, about the minimum seat post insert of the frame or a seat post minimum insert, please consult with your dealer or a professional bicycle mechanic. Failure to insert and maintain either frame seat post minimum insert and also seat post minimum insert can place very high stresses on these parts causing failure while riding. You can be severely injured, paralyzed, or killed in an accident if you ignore this warning.

Seat Post
Installation & Adjustment
Before installing:

• To ensure good clamping and avoid creaking, remove all residual carbon paste with a clean cloth dampened with rubbing alcohol. Wipe the inside of the seat tube and seat post. Wipe again using a clean area of the cloth and repeat until the cloth comes away clean.
• Apply fresh carbon friction paste to the seat post and place a little bit inside the seat tube.
• Lightly grease the seat tube under the seat post clamp.

To adjust:

1. Insert the prepared seat post into the frame.
2. Set the saddle height. Maintain the specified minimum insert.
3. Tighten the binder screw to the specified torque.

NOTICE
Do not exceed the specified torque. If you over-tighten the binder bolt, you will damage the binder, seat post, or frame.
Minimum Insert
The minimum insert depth the seat post must be inserted into the frame is 100mm.
Maximum Insert
The total length of seat post that may be inserted will vary with the frame size and should be checked in each frame.
To check, carefully slide a seat post into the frame until it stops; then lift it up 5mm.
NOTICE
A seat post should not be bottomed out inside the frame at any time. If necessary, have your Cannondale dealer cut the seat post appropriately.
WARNING
THE SEAT POST MUST ONLY BE CUT BY A PROFESSIONAL BIKE MECHANIC. Incorrectly cutting the seat post can result in damage leading to an accident.
For more information about carbon fiber seat posts, see also “Care and Maintenance of Carbon Fiber Seat Posts” in your Cannondale Bicycle Owner’s Manual.

   WARNING
   Do not ride the bike with the chain guide removed, or in a damaged condition. Replace it with a new one.

To set the position of the chain guide:

1. Shift the chain onto the largest cog on the rear cassette.

2. Position the flat surface of the chain guide head 1mm above the chain as shown next figure. The pointed end faces forward on the bike.

3.  Place a 1mm Allen key flat on top of the chain so its flat side contacts the chain and the guide lower surface and lower the chain guide into the Allen key, then tighten to 2-3 Nm.

4. Test to confirm the chain guide is operating properly by pulling the chain towards the outside of a slowly rotating chain, attempting to derail the chain, while pedaling it forward (by hand) in the work stand. The chain should not come off of the guide. If the chain does come off of the guide, slightly lower the guide until it does not.
   WARNING
   keep fingers away from the chain ring.

5. Confirm the chain guide does not rub while the rider is pedaling the bike in the largest cassette cog.
