INTRODUCTIONCongratulations on your purchase and welcome to the finest line of suspension bikesavailable!About Off Road, Stunt, Downhill and FreeridingThis manual is designed to be used in conjunction with the Bicycle Owner’s Manualand owner’s manuals supplied by the manufacturer of the front and rear suspensioncomponents. If you did not receive any of these manuals, download them from theInternet, contact your dealer, or contact us by telephone. There may be more currentmanuals and technical information available. For the most current information , regularlycheck the Specialized web site or consult your Specialized dealer. These manuals werewritten for an important reason: your safety while riding.This manual contains many “Warnings” and “Cautions” concerning the consequencesof 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 potentiallyhazardous situation which, if not avoided, could result in serious injury or death. Thecombination of the safety alert symbol and the word Caution indicates a potentiallyhazardous situation which, if not avoided, may result in minor or moderate injury, ordamage to your bicycle or a component. Because the consequences of not followinga Warning usually include “you may lose control and fall,” which could result in seriouspersonal 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, apractice or situation may be unsafe but not anticipated by this manual. So, don’t forget touse 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 FREERIDINGDownhill racing, severe off road riding, jumping, and stunt riding is extremelydangerous. Some downhill racers and freeriders reach speeds similar to motorcycles, thusface similar risks and hazards. When engaging in these activities, you, your bicycle andsafety equipment must be in perfect condition. We recommend that at all times you wearappropriate safety gear, such as an approved full face helmet, full finger gloves, and bodyarmor.Not every bicycle is built for every activity. Check with your Specialized dealer to makesure you have the right equipment.No bicycle is indestructible. Downhill racing, severe off road riding, jumping, and stuntriding increases the stress on every part of your bicycle. Frames or parts under high stressmay fail, causing you to lose control or fall. Because of the risk involved, Specializedrecommends 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 yourselffor 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 internaland hidden, if any of these signs are present, stop riding until your bicycle has beenthoroughly inspected by your Specialized dealer.2


WARNING! Although many catalogs, advertisements and articles about bicyclingdepict riders racing, jumping, riding hard off road, and/or stunt riding, this activity isextremely dangerous, increases the rider’s risk of injury or death, and potentiallyincreases the severity of any injury. The action depicted is being performed by expertswith 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 foreseeablethat during some jumps or stunts, and even some races, that the rider will exceed thedesign capacity of the frame or components, which may result in something on thebicycle bending or breaking. If a frame or component bends or breaks, such may leadto loss of control, serious personal injury or death.As activities such as racing, jumping, severe off road riding, and stunt riding areextremely dangerous, SAFETY should always be the first consideration. Don’t ride inthe race, ride hard off road, try the jump, or do the stunt, UNLESS YOU CAN DO SOSAFELY. 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 moredangerous jumps or stunts.• Wear appropriate safety gear, such as a full face helmet, body armor, full finger gloves.• Make sure by checking with your dealer that your bike is suitable for the kind of activityyou intend to engage in.• Constantly inspect your bicycle for signs of stress: cracks in the paint; dents; crushingor bending of the frame; bent components. Do not ride your bicycle if it shows suchsigns 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 lossof control, serious injury or death.Specialized does not warrant the bicycle frame or components for such activities, andexpressly disclaims all warranties, including the warranty of fitness for particular purposeand merchantability.Stunt riding, severe off road riding, jumping, or riding downhill at speed is extremelydangerous, and the rider voluntarily assumes the risk that the bicycle frame and/or itscomponents will bend or break, and voluntarily assumes the risk of injury or death.SERVICE AND MODIFICATIONSTechnological advances have made bicycles and bicycle components morecomplex, and the pace of innovation is increasing. It is impossible for this manual or theaccompanying manuals to provide all of the information required to properly repair and/ormaintain your bicycle. In order to help minimize the chances of an injury, it is critical for youto have work performed by an authorized Specialized retailer.WARNING! Service on Specialized bicycles requires special knowledge and tools.Specialized recommends that all service and repairs be performed by an authorizedSpecialized retailer.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 andapprove of all possible combinations. Modifying the frame, fork, or any of the componentsmay make your bike unsafe. For example, changing the front suspension on your bicyclemay alter the steering characteristics and/or add stresses to the frame which have notbeen tested for. If you must replace any component, have this done by your authorizedSpecialized retailer.3


WARNING! Never modify your frame or bicycle in any way. Do not sand, drill, fill, orremove parts. Do not install incompatible forks or suspension parts. An improperlymodified frame, fork, or component, can cause you to lose control and fall.CAUTION: Any modification of your frame, fork, or components means that yourbike no longer meets our specifications and therefore voids your warranty.FORK SETUPWARNING! The BigHit frames are compatible with single and dual crown forks thathave travel of 7.875” (200mm) or less. Use of different styled forks or forks withlonger travel may result in catastrophic failure of the frame which may result inserious personal injury or death.SEAT POST SETUPSEATPOST MINIMUM INSERTION: Toprevent damage to the frame, it’s important tohave a minimum amount of seatpost in the seattube.If you cannot see the seatpost tube through theseat tube hole, your seatpost is too far extended.If a greater saddle height is required, replace theseatpost with a longer one.100mmMinimum SeatpostInsertion Guide HoleFRONT DERAILLEUR SETUPDerailleurposition:LOWDerailleurposition:HIGHStumpjumper FSR 26”Stumpjumper FSR 29erEpicEnduroSafirePitchEpic 29erEraSX / SX TrailBigHitThe front derailleur chart is a starting point.

Set rebound damping adjuster to rider preference.• Slower rebound for slow speed, bigger hits to eliminate kickback.• Faster rebound for higher speeds, smaller hits and more traction, so the suspensiondoes not pack up and has time to rebound between bumps.SETTING INTERNAL FLOATING PISTONDHX 4.0 ONLY: The IFP (Internal Floating Piston) sets up the overall rate ofcompression damping.• Higher pressure offers more bottom control• Lower pressure offers less bottom controlPressure range for IFP: 125 - 200 PSISETTING PROPEDALDHX 4.0 ONLY: ProPedal affects the first part of the compression stroke (slow speed)and controls rider induced suspension bob.• Clockwise increases ProPedal (more efficient pedaling).• Counter-clockwise decreases ProPedal (more supple ride, more traction).8
