Geometry

Dimensions = millimeter

Notes:
Rear axle Flip Chip adjusts the Chainstay Length between 440mm and 450mm with a 29er rear wheel and 435mm and 445mm with a 27.5 rear wheel. No other frame geomtery changes when switching between 29 and 27.5 rear wheels when using the Flip Chip. The Shock Flip Chip changes shock progression and has no effect on frame geometry.

Pivot Axles
To remove pivot axles:

1. Unthread and remove idler, idler bolt, and spacer if present (only on main pivot).
2. Using an M6 bolt of threaded length > 30mm, thread the bolt through the exposed wedge thread. Continue until the wedge is loosened.
3. Remove M6 bolt from main axle and remove wedge from M6 bolt.
4. Using 6mm Hex, unthread and remove main axle.

To install the pivot axles:

1. Disassemble and clean all parts of the pivot axle. Inspect the parts for damage (e.g., burrs, scratches, deformity, wear). Replace the entire pivot axle with a new one if necessary.
2. Apply a light coating of a high-quality bicycle bearing grease to the pivot axle surfaces, axle and screw threads, and the wedge.
3. Align the linkage system and insert the threaded end of the pivot axle from the non-drive side.
4. From the non-drive side, tighten the inserted pivot axle to 5 Nm using a 6mm hex key fitted to a torque wrench.
5. Insert the small end of the wedge into the non-drive side pivot axle head.
6. Thread the screw through the wedge and tighten to 5.0 Nm.

Please Note: The idler gear assembly is fixed to the drive-side end of the main pivot axle. The idler assembly must be removed first when installing the main pivot axle and last after install the main pivot axle.

Rear Shock
Setting Sag

1. Follow the shock manufacturer's instructions for setting the shock according to rider weight.
2. 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.
3. Measure the Sag.
4. Dismount and adjust the air pressure or coil spring preload of the shock. Repeat steps 2 through 4 to achieve the correct Sag measurement.

Removal/Installation Points:

• Always clean the mounting hardware and frame interfaces with a clean dry lint-free shop towel prior to assembly.
• Clean and re-grease the frame pockets where the leverage chips are inserted.
• Lightly grease the spacers.
• Always re-apply threadlocker as indicated, and lightly grease under the bolt heads
• Lightly grease the trunnion spacers.
• Always re-apply threadlocker as indicated, and lightly grease under the bolt heads.
  NOTICE
  Install shock with adjusters/reservoirs positioned to the front of the bike.
• Install the lower shock bolt into the non-drive side, as shown.
• Tighten bolts to the specified torque.

Changing Leverage Chips
Select between a Progressive or Linear rear shock response by changing the installed position of the lower shock leverage chips. See next figure, lower.
PROGRESSIVE - better big hit performance
LINEAR - more support in cornering The leverage chip positioning is a matter of rider preference and can be selected independently of the current seatstay or dropout chips set-up.

4. Thread non drive side cup in regular right-hand thread per manufacturer torque spec
5. Wipe off excess grease
6. The chainring should be in-line with the idler sprocket OR slighter outboard of the idler sprocket -this depends on the crank and both are as designed.

Changing Rear Wheel Size
The seatstay/link chips can be installed for either a 27.5" or 29" rear wheel. See next figure, lower. The selected position of the chip in either the 27.5" or 29" wheel position can be made independently of the positions of either the rear shock leverage or rear dropout chips.

Secure the bike in a work stand first. Before working on the suspension linkage, remove the wheel. Take addtional steps to support the swingarm from dropping or moving unexpectedly.

Removal/Installation Points:

• Always clean the mounting hardware and frame interfaces with a clean, dry, lint-free shop towel prior to assembly.
• Clean and re-grease the pockets where the chips are inserted. See next figure inset.
• Lightly grease the spacers.
• Always re-apply threadlocker indicated, and lightly grease under the bolt heads
• Install the corresponding rear wheel size.

Match the installed seatstay/link chips position with the wheel size to be installed in the rear dropouts.
After making a change to the chip position and installed wheel, make sure the rear brakes are set-up correctly for the different wheel and that the brake operates normally before riding.

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 (e.g., frame, stem, fork, handlebar, seat post, etc.). Ask your GT Dealer for help.
We urge you to read Section "Inspect For Safety" in your GT 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 Section Inspect For Safety in your GT Bicycle Owner's Manual. )
Do not ride your bike if you see any signs 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, or a white / 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

The intended use of all models is ASTM CONDITION 5, Downhill.

Understand your bike and its intended use. Using your bike the wrong way is dangerous.
Please read your GT Bicycle Owner's Manual for more information about Intended Use and Conditions 1-5.

Freeriding & Downhill

FREERIDING AND OTHER FORMS OF "EXTREME RIDING" ARE EXTREMELY DANGEROUS. YOU CAN BE SEVERELY INJURED OR KILLED IN A SERIOUS ACCIDENT.
Freeriding, jumping, hucking, dirt jumping, mountaincross, downhill, slalom, slopestyle, urban or street riding or other evolving forms of extreme or hard core mountain biking are inherently dangerous and can lead to serious accidents. Wear all safety gear and be sure your bike is in excellent condition. Follow all the instructions and warnings below. These steps will reduce, but not eliminate, the inherent risks. Even with state of the art protective safety gear you could be seriously injured, paralyzed or killed. If you do not want to take these risks, do not engage in this type of riding.

Fundamental Risk
Freeriding, jumping, hucking, dirt jumping, mountaincross, downhill, slalom, slopestyle, urban or street riding. It seems that everywhere you look, from Mountain Dew® commercials to the X-Games® to the Red Bull®Rampage, riders are grabbing big air and sticking sick drops. And it sure looks fun.
But what the videos and bike magazines and ads don't always tell you is that extreme riding takes an amazing amount of skill. Some of the riders you see are well-paid pros who have gradually built up their skills through endless hours of practice, and who have also had their share of stitches, concussions and busted bones (and bikes). Others are daredevils who have chosen to accept or ignore the risks. Would you allow anyone to say that you are so weak in the head, and have such poor judgment that you copy those you see in the media without thought of the serious risks?
The stakes are high if you screw up. Realize too late that you aren't up to the challenge, and you run the risk of major injury or even – say it aloud – death, paralysis. In short, extreme riding carries a high degree of fundamental risk, and you bear the ultimate responsibility for how you ride and what you attempt to pull off. Do you want to avoid these significant risks? Then do not ride this way.

Product Limitations
Problems of pilot error aside, hard-core riding also beats the heck out of your equipment. Although we build and test our bikes to make them tough, there's no way that we can guarantee they'll survive your umpteenth six-foot drop. For starters, there is no industry "jumping" standard. The many circumstances of takeoff, landing, speed, rider technique, etc. are unique. The judgment, lack of judgment or insanity of a rider who may ride a GT Bicycle cannot be completely predicted, so it's flat-out impossible to predict how anyone's equipment is going to hold up. (continued on next page...)

Let's get another thing straight. Buying a Freeride bike does not make you any better. Do not confuse the built-in capabilities of equipment with your own capabilities, which must be learned.
Keeping your bike and all its components in good working order is critical, and it's up to you to maintain and inspect it. Even so, your sweet rig isn't going to last forever. Nothing does, particularly bikes and parts that are built to minimize weight and then are subjected to abuse. GT frames carry a warranty, but that's to cover issues with workmanship and/or materials. (See the GT Limited Warranty in this manual). The warranty doesn't mean that they're going to last forever. They're not. The warranty certainly doesn't mean that the bicycle can in any way protect you from injury.

You must select a replacement fork based not only on headtube diameter but also on the frame's maximum fork length.
Do not exceed the frame's maximum fork length. Doing so 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 GT bicycles, see www.gtbicycles.com.
You can be severely injured, paralyzed, or killed in an accident if you ignore this warning.

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, saddles, seat post, or seat post clamps seat post 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 following:
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.

Rear Tire Clearance: Full Suspension

Applies to:

1. Release all the air from the rear shock. Remove the coil spring from coil shocks (spring coil removal should only be done by a professional bike mechanic). Do not disconnect or remove the shock.
2. Compress the suspension fully with the tire inflated to its maximum inflation pressure.
3. At various points across the tire, measure the distance between the tire and the component or accessory.
4. If there is less than 10 mm of clearance available, the component or accessory must be adjusted or changed until there is at least 10 mm of clearance.

Maintain 10 mm of clearance between rear tire, any rear rack, saddle, seat post, frame seat tube, or any mounted accessory.
Check following saddle or seat post adjustments.
If you have questions maintaining tire clearances for parts of your bike, consult with an Authorized Dealer or with a professional cycling mechanic.
You can be severely injured, paralyzed, or killed in an accident if you ignore this warning.

Rear Shock

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 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.

Making Adjustments

To prevent personal injury: Before making flip chip adjustments, place the bike in a work stand and remove the rear wheel. Keep your hands and finger out of pinch points of moving suspension parts. Take additional steps to prevent the swingarm from dropping or moving unexpectedly.

Minimum Seat Post Insert

Tinimum seat post insert length for your frame is found in the Frame SPecifications table in this manual.
Make sure the specified length is = inserted into the frame at all times.
Failure to insert the specified seat post length can place a very high stress on the seat tube / top tube junction, causing the frame to fail while riding.
The specified length is measured from the bottom of a removed seat post. You can use a permanent marker tto make the specified length on the seat post.
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.
