137365 Rev 1. 1 SAFETY INFORMATION
Important Composites Message 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 warning. Inspection & Crash Damage Of Carbon Frames/Forks 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.

Intended Use English Tightening Torques The intended use of all models is ASTM CONDITION 4, All-Mountain. Please read your Cannondale Bicycle Owner’s Manual for more information about Intended Use and Conditions 1-5. Servicing 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 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. 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 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 listed on the websites of component manufacturers. • With your dealer. Dealers have access to current data and have experience with correct torque for most fasteners.
137365 Rev 1. 3 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, headset adapters, installing and adjusting a fork, and selecting replacement forks. From Bottom Of Frame Head Tube Maximum Fork Length To Center Of The Fork Axle 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 cannondale.com. You can be severely injured, paralyzed or killed in an accident if you ignore this warning. 137365 Rev 1. 4 English Tire Size x Maximum Width 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 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 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 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. 137365 Rev 1. 5
Rear Shocks 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 different 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. You can be severely injured, paralyzed or killed in an accident if you ignore this warning. Minimum Seat Post Insert Make sure at least 100 mm of the seat post is inserted into the frame at all times. Failure to insert the seat post at least 100 mm can place a very high stress on the seat tube top tube junction causing the frame to fail while riding. Remove the seat post. Measure 100 mm from the bottom of the seat post. Use a permanent marker to mark the post at 100 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.

Dropout 6 Nm Loctite 242 (blue) English KP169/ small end Maintenance The condition of the bearings, pivot axles, and spacers should be inspected periodically. These are normal wear parts so plan to have them renewed as they wear-out. Inspection frequency should be based upon how and where you ride. Evidence of damage would be excessive play, visible wear, or perhaps corrosion of bearings. If you find any damage to the parts, discontinue riding until all the parts (bearings, pivot axles, spacers) can be renewed. This will help prevent damage elsewhere. See the kits list in the back of this supplement for renewal kits. Key Information: A special service tool KP169/ contains parts necessary to service the assembly. The parts of this tool are shown shaded above. When connecting the seat stays to the dropouts, always insert the small end of pivot spacers into the dropout bearings . The flat side of the spacers should face out, as shown. When tightening the axles, insert the 5 mm hex key completely into the axle to prevent damage when turning the bolt. Always tighten with a torque wrench to the specified torque.

2020 Jekyll - Owner’s Manual Supplement Asymmetric Integration - Ai Rear Wheel- 3 mm Offset The Ai rear hub is offset 3 mm 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. • Ai wheels have equal spoke angles and tension on both sides (non-dished wheel) which improves wheel stiffness, strength. • The 3mm offset is for 148 X 12mm spacing only! • Other Ai equipped bike with 142mm or 135mm rear spacing use a 6mm offset. NOTICE USE ONLY 3mm “Ai” OFFSET REAR WHEELS. Incorrect wheel offset can damage your frame. Standard wheel assembled on this frame will result in insufficient tire clearance leading to rubbing and serious frame damage. This kind of damage is not covered by the Cannondale LimitedWarranty. Building/Truing a Wheel If you chose to build, or true the wheel, make sure the 3 mm offset is present. Consult with your Cannondale Dealer if you have any questions. NON-DRIVE DRIVE 3mm 148mm
