Congratulations on your purchase and welcome to the ﬁnest line of suspension bikes

available!

About Off Road, Stunt, Downhill and Freeriding

This manual is designed to be used in conjunction with the Bicycle Owner’s Manual and owner’s manuals supplied by the manufacturer of the front and rear suspension components. If you did not receive any of these manuals, download them from the Internet, contact your Specialized Authorized Dealer, or contact us by telephone. There may be more current manuals and technical information available. For the most current information, regularly check the Specialized web site or consult your Specialized Authorized Dealer. These manuals were written for an important reason: your safety while riding.

This manual contains many “Warnings” and “Cautions” concerning the consequences of failure to maintain or inspect your bicycle or of failure to follow safe cycling practices. The combination of the safety alert symbol and the word Warning indicates a potentially hazardous situation which, if not avoided, could result in serious injury or death. The combination of the safety alert symbol and the word Caution indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury, or damage to your bicycle or a component. Because the consequences of not following a Warning usually include “you may lose control and fall,” which could result in serious personal injury or death, we may not repeat this in conjunction with each Warning. Because it is impossible to anticipate every situation or condition which may occur, a practice or situation may be unsafe but not anticipated by this manual. So, don’t forget to use your common sense.

WARNING! Make sure you have, review, and understand the warnings, instructions, and content of the manuals for your bicycle.

ABOUT OFF ROAD, STUNT, DOWNHILL AND FREERIDING

Downhill racing, severe off road riding, jumping, and stunt riding is extremely dangerous. Some downhill racers and freeriders reach speeds similar to motorcycles, thus face similar risks and hazards. When engaging in these activities, you, your bicycle and safety equipment must be in perfect condition. We recommend that at all times you wear appropriate safety gear, such as an approved full face helmet, full ﬁnger gloves, and body armor.

Not every bicycle is built for every activity. Check with your Specialized Authorized Dealer to make sure you have the right equipment.

No bicycle is indestructible. Downhill racing, severe off road riding, jumping, and stunt riding increases the stress on every part of your bicycle. Frames or parts under high stress may fail, causing you to lose control or fall. Because of the risk involved, Specialized recommends that you conduct a thorough inspection before each ride. If you miss a jump, ditch your bike in mid crash, dump or launch your bike without you on it, inspect yourself for injury, then carefully inspect your bicycle for damage.

Here is what you should look for when you inspect your bicycle for this type of riding: bent or broken components, such as the handlebar, handlebar stem, seatpost, pedals; dents, cracks, scratches, deformation, or discoloration. Because damage may be internal and hidden, if any of these signs are present, stop riding until your bicycle has been thoroughly inspected by your Specialized Authorized Dealer.

WARNING! Although many catalogs, advertisements and articles about bicycling depict riders racing, jumping, riding hard off road, and/or stunt riding, this activity is extremely dangerous, increases the rider’s risk of injury or death, and potentially increases the severity of any injury. The action depicted is being performed by experts with many years of training and experience. Even with that training and experience, cyclists who engage in such activity often get seriously injured. It is also foreseeable that during some jumps or stunts, and even some races, that the rider will exceed the design capacity of the frame or components, which may result in something on the bicycle bending or breaking. If a frame or component bends or breaks, such may lead to loss of control, serious personal injury or death.

As activities such as racing, jumping, severe off road riding, and stunt riding are extremely dangerous, SAFETY should always be the ﬁrst consideration. Don’t ride in the race, ride hard off road, try the jump, or do the stunt, UNLESS YOU CAN DO SO SAFELY. Here are some additional recommendations:

 Take lessons from a competent instructor ﬁrst.

 Do jumps or stunts only in areas designated for this type of riding.

 Start with easy jumps and easy stunts ﬁrst, and slowly develop skills before trying

more dangerous jumps or stunts.

 Wear appropriate safety gear, such as a full face helmet, body armor, full ﬁnger

gloves, etc.

 Make sure by checking with your Specialized Authorized Dealer that your bike is

suitable for the kind of activity you intend to engage in.

 Constantly inspect your bicycle for signs of stress: cracks in the paint; dents;

crushing or bending of the frame; bent components. Do not ride your bicycle if it shows such signs of stress.

 Do not seek to bend or break the frame or components. Remember, SAFETY FIRST!!!

Understand and recognize that the stresses imposed on your bike by riding at speed, jumping or stunt riding may break or damage parts of the bicycle, which may result in loss of control, serious injury or death.

Specialized does not warrant the bicycle frame or components for such activities, and expressly disclaims all warranties, including the warranty of ﬁtness for particular purpose and merchantability.

Stunt riding, severe off road riding, jumping, or riding downhill at speed is extremely dangerous, and the rider voluntarily assumes the risk that the bicycle frame and/or its components will bend or break, and voluntarily assumes the risk of injury or death.

SERVICE AND MODIFICATIONS

Technological advances have made bicycles and bicycle components more complex, and the pace of innovation is increasing. It is impossible for this manual or the accompanying manuals to provide all of the information required to properly repair and/or maintain your bicycle. In order to help minimize the chances of an injury, it is critical for you to have work performed by an Specialized Authorized Dealer.

WARNING! Service on Specialized bicycles requires special knowledge and tools. Specialized recommends that all service and repairs be performed by a Specialized Authorized Dealer.

Your bicycle has been engineered and tested with speciﬁc components and parts. Because of the great variety in these items, it is impossible for Specialized to test and approve of all possible combinations. Modifying the frame, fork, or any of the components may make your bike unsafe. For example, changing the front suspension on your bicycle may alter the steering characteristics and/or add stresses to the frame which have not been tested for. If you must replace any component, have this done by your Specialized Authorized Dealer.

WARNING! Never modify your frame or bicycle in any way. Do not sand, drill, ﬁll, or remove parts. Do not install incompatible forks or suspension parts. An improperly modiﬁed frame, fork, or component, can cause you to lose control and fall.

CAUTION: Any modiﬁcation of your frame, fork, or components means that your bike no longer meets our speciﬁcations and therefore voids your warranty.

FORK SETUP INFORMATION

WARNING! The Stumpjumper frames are compatible ONLY with single crown forks that have a speciﬁc maximum amount of travel (see table below). Use of different styled

forks or forks with longer travel may result in catastrophic failure of the frame which may result in serious personal injury or death.

BOTTOM BRACKET ASSEMBLY

Certain Stumpjumper frames are equipped with 73mm PF30 bottom bracket shells. This design allows for the installation of Specialized OSBB carbon cranks, or the installation of different adapters to ﬁt a variety of crank offerings. All documents are available at www. specialized.com

 For Specialized carbon crank installation, please refer to the carbon crank guide

(IG0276 - Crankset - Carbon MTB crankset).

 For all other options, please refer to the crank compatibility guide (CG0308 -Bottom

Bracket - Oversized MTB Bottom Bracket).

SEATPOST SETUP INFORMATION

SEATPOST MINIMUM INSERTION: To prevent damage to the frame, it’s important to

have a minimum amount of seatpost in the seat tube.

Carbon frames:

Small / Medium - 70mm insertion

Large / X-Large - 100mm insertion

Aluminum frames:

If you cannot see the seatpost tube through the seat tube hole, your seatpost is too far extended. If a greater saddle height is required, replace the seatpost with a longer one.
