Suspension sag is the percentage of full travel that the suspension compresses when the rider, including gear, is on the bicycle in a normal riding position. Setting the correct sag allows the suspension to perform effectively. Optimal suspension sag is the result of setting the proper suspension spring rate.

• More sag (20% - 30%) increases bump sensitivity and suspension movement. More bump sensitivity results in a smoother ride and is typically preferred on longer travel bicycles.

• Less sag (10% - 20%) decreases bump sensitivity and suspension movement. Less bump sensitivity results in a more firm, efficient ride and is typically preferred on shorter travel bicycles.

• Too much sag is an indicator that the spring rate should be increased by either increasing air spring pressure or changing the coil spring to a stiffer spring.

Air spring suspension forks: Air pressure, after sag is set, may differ from the recommended starting air spring pressure printed on your fork based on travel, bicycle geometry, and rider preference.

Important: Sag must be set before making any damping adjustments.

Sag Gradients: Many RockShox forks and rear shocks include sag percentage gradients and a sag o-ring on one upper tube, or the rear shock body or shaft. If a sag o-ring is not on your suspension, install a plastic cable tie around the upper tube, shock body or shock shaft, just tight enough so it does not move. Remove the cable tie before riding.

If your fork or rear shock does not have sag percentage gradients, to calculate target sag, multiply the target sag percentage by the total amount of suspension travel. Use a ruler to measure the length of exposed upper tube, damper body or shock shaft above the wiper seal to the sag o-ring.

If your suspension's travel is unknown, before sag is measured, fully compress the suspension to bottom out. Release and use a ruler to measure the length of exposed upper tube, damper body, or shock shaft below the sag o-ring or stopping point of the wiper seal.

Getting started: Front suspension air pressure recommendations listed on the back of your fork, and at RockShox Trailhead, are suggestions for initial spring setup. Front suspension coil springs are available in a number of spring rates ranging from soft to extra firm. Refer to the appropriate model year RockShox Front Suspension Oil, Air, Coil, Token, and Specification document for coil spring recommendations based on rider weight.

Before setting sag, set all dampers (rebound and compression) to the full open positions.

1. Rotate each adjuster knob counterclockwise until they stop.

2. Remove the air cap.

3. Pressurize the air spring to the recommended starting air pressure on the fork decal or RockShox Trailhead. For Dual Position Air forks, pressurize the fork in the full travel position. Remove the pump.

4. Solo Air and DebonAir only: Compress the fork through at least 50% of travel 5 times to equalize positive and negative air pressures. Air pressure equalization ensures the positive air spring is accurately pressurized.

5. Pressurize the air spring to the same recommended starting pressure once more. Remove the pump.

6. Solo Air and DebonAir only: Compress the fork through at least 50% of travel 5 more times to equalize positive and negative air pressures.

7. With riding gear on, and an assistant holding the bike, stand on the pedals and compress the fork three times. Then sit or stand in your normal riding position.

8. Have your assistant slide the sag o-ring down to the top of the dust wiper seal.

9. Gently step off the bicycle without compressing the fork any further. Note the sag percentage where the o-ring stopped.

If your fork does not have sag percentage gradients, to calculate target sag, multiply the target sag percentage by the total amount of suspension travel. Use a ruler to measure the length of exposed upper tube above the wiper seal to the sag o-ring.

If your target sag percentage is not achieved, air pressure must be adjusted.

Increase air pressure to decrease sag, and decrease air pressure to increase sag.

Repeat the sag process until your target sag percentage is achieved.

Rudy XPLR: Target sag is 5%.

Sag is the amount (percentage) the suspension compresses when the rider, including riding gear, is seated on the bicycle in the riding position.

Setting proper sag allows the wheels to maintain traction without using too much travel reserved for shock absorption.

More sag increases small bump sensitivity, while less sag decreases small bump sensitivity.

Check spring sag and replace the coil spring if necessary, before making any other tuning adjustments.

1-2. Before setting sag, set the dampers to the full open positions. Rotate the adjusters counterclockwise until they stop.

Remote: Set the compression damper to the open position.

1. Turn the preload adjuster knob counterclockwise until it stops.

This is the least amount of spring preload, or the softest setting.

Dual Position Coil: Does not include a preload adjuster. Set the spring to full travel.

2. With riding gear on, and an assistant holding the bike, stand on the pedals, and compress the fork three times. Then sit or stand in your normal riding position.

3. Have your assistant slide the sag o-ring down to the top of the dust seal.

4. Gently step off the bicycle without compressing the fork any further.

5. Note the sag percentage where the o-ring stopped.

If your target sag percentage is not achieved, spring preload adjustment and/or coil spring replacement must be performed.

External spring preload adjustment compresses or decompresses the spring without initiating travel.

A. Turn the preload adjuster knob clockwise to increase spring preload and decrease sag.

B. Turn the preload adjuster knob counterclockwise to decrease spring preload and increase sag.

Spring preload adjustment can be used to fine tune sag, but preload does not change spring rate and is not a substitute for the proper coil spring weight.

If the proper sag cannot be achieved after external preload adjustment, the coil spring assembly must be replaced with a softer or firmer spring.

• To increase sag, install a softer coil spring assembly.

• To decrease sag, install a firmer coil spring assembly.

Repeat the sag process until your target sag percentage is achieved.

1. With riding gear on, and an assistant holding the bike, stand on the pedals, and compress the fork three times. Then sit or stand in your normal riding position.

2. Have your assistant slide the sag o-ring down to the top of the dust seal.

3. Gently step off the bicycle without compressing the fork any further.

4. Note the sag percentage where the o-ring stopped.

If your target sag percentage is not achieved, spring preload adjustment and/or coil spring replacement must be performed.

Preload spacers compress or decompress the spring without initiating travel.

The coil spring can be preloaded with the maximum number of preload spacers specified for the fork model. Refer to the Service Manual for your fork for more information.

• Remove preload spacers to decrease preload and increase sag.

• Install preload spacers to increase preload and decrease sag.

Spring preload can be used to fine tune sag, but preload does not change coil spring rate and is not a substitute for the proper coil spring.

If your target sag cannot be achieved with the maximum number of preload spacers, replace the coil spring with a firmer spring.

If your target sag cannot be achieved with zero preload spacers, replace the coil spring with a softer spring.

Repeat the sag process until your target sag percentage is achieved.

Due to the specificity of frame designs, it is best to follow the Set Sag - Rear Suspension (Air or Coil) procedure to determine the correct spring rate. Rear shock coil springs are available in a number of spring rates based on the eye-to-eye shock length and compression stroke dimensions of your shock. Refer to the (RockShox) Spare Parts Catalog for available springs.

1-2. Before setting sag, set the adjusters to the unlocked or full open positions. Rotate the adjusters counterclockwise until they stop, to the unlocked or full open setting.

Vivid Air (Gen C): Before setting sag, rotate the Low Speed Compression (2.1) and High Speed Compression (2.2) adjusters to the middle setting.

Remote: Set the shock to the open position.

3. Remove the air cap.

4. Beginning with the shock fully deflated, pressurize the air spring chamber to 100 psi.

Vivid Air (Gen C): Beginning with the shock fully deflated, pressurize the air spring chamber to 50 psi.

Remove the pump. Do not compress the suspension with the pump attached.

5. Fully compress the shock five times to equalize the positive and negative air springs. Air pressure equalization ensures the air spring is accurately pressurized.

6. Pressurize the shock (PSI) to the equivalent of the rider's total weight (lbs), including gear. Example: 160 lbs = 160 PSI

Vivid Air (Gen C): Repeat steps 4 and 5 in 50 PSI increments up to the rider's total weight (lbs), including riding gear.

Remove the pump. Do not compress the suspension with the pump attached.

7. Compress the shock once more to equalize air pressure.

8. With riding gear on, and an assistant holding the bike, step onto the bicycle and lightly cycle the shock two to three times while in the standing position on the pedals.

9. While seated on the bicycle, have an assistant slide the sag o-ring against the wiper seal.

10. Gently step off the bicycle without compressing the shock.

11. Note the sag percentage where the o-ring stopped.

Correct sag percentage for Solo Air shocks is ≈25%. Correct sag percentage for DebonAir shocks is ≈30%.

Sag can be set ±5% as preferred. Adjust pressure and retest sag as needed.

If your target sag percentage is not achieved, air pressure must be adjusted.

Increase air pressure to decrease sag.

Decrease air pressure to increase sag.

Refer to Coil Spring Installation for coil spring removal and installation procedures.

1-2. Set the rebound, compression, and threshold settings to the full open position.

3. Turn the spring preload adjuster counterclockwise until there is no resistance.

4. Turn the preload adjuster clockwise two full turns and stop.

5. Slide the bottom out bumper to the shock body.

6. With riding gear on, and an assistant holding the bike, step onto the bicycle and lightly cycle the shock two to three times.

7. While seated on the bicycle, have an assistant slide the bottom out bumper against the wiper seal.

8. Gently step off of the bicycle without compressing the rear shock.

9. Check the top of the bottom out bumper position on the shock shaft and note the sag percentage marking.

If the shaft does not include markings measure the shaft length with a ruler.

Correct sag should be between 25% and 35%. Depending on your riding style and terrain, sag can be set 5% more or less than the recommended amount.

If the sag value is not at the desired level, turn the preload adjuster ring and repeat the measuring process until the desired sag value is achieved.

If the sag value is not at the desired level after five full clockwise turns, a heavier spring must be installed, and the sag setting procedure must be repeated.

Ending stroke air spring ramp, or bottom out resistance, can be tuned on select RockShox air spring forks compatible with air spring volume reducing Bottomless Tokens, as well as select RockShox air spring rear shocks compatible with air spring volume reducer Bottomless Tokens and Rings.

Bottomless Tokens and Rings reduce air spring volume and increase bottom out resistance. Reduced volume, with the correct sag set, increases mid to ending stroke spring ramp without significantly affecting sag and small to medium bump sensitivity. Increased spring ramp at bottom out can be beneficial on larger drops or fast bumpy trails where the fork uses most of its travel.

If sag is set correctly and the suspension bottoms out quickly and often, try adding compatible Bottomless Tokens, or Rings, until you find the preferred bottom out feel.

It is recommended that you repeat the Sag process and make damping adjustments after volume reducers have been installed or removed. Adding volume reducers may cause the suspension to rebound quicker. Rebound damping may need to be increased to compensate.

To avoid damaging the fork or rear shock, the maximum number of Bottomless Tokens or Rings installed should not be exceeded. For suspension forks, refer to the appropriate model year RockShox Front Suspension Oil, Air, Coil, Token, and Specification document for the maximum number of Bottomless Tokens compatible with your fork. For rear shocks, refer to the Service Manual for your rear shock, for the maximum number of Bottomless Tokens and Rings.

For a complete list of available Bottomless Tokens and Rings consult the (RockShox) Spare Parts Catalog. For volume reducer installation and removal procedures, consult the service manual for your fork or rear shock. All related technical documents can be found at sram.com/service.

Additional rings or tokens increase bottom out resistance. Removing rings or tokens decrease bottom out resistance.

Front Suspension: Refer to the product Service Manual or the RockShox Front Suspension Oil, Air, Coil, Token, and Specification document for the maximum number of Bottomless Tokens.

Rear Suspension: Refer to the product Service Manual for the maximum number of Bottomless Tokens and Rings.

Volume reducers can be installed onto the sealhead/ fixed piston and/or on the Linear XL air can to achieve the same effect.

• 1 Bottomless Token Large (A) equals 2 Linear XL air can Sleeve Tokens (C).

• 1 Bottomless Token Small (B) equals 1 Linear XL air can Sleeve Token (C).

To achieve maximum suspension performance, proper setup and tuning is essential.

Tuning sections in this manual will help to identify and understand the features and adjustments that may be included on your RockShox suspension, as well as guide you through spring setup, damper adjustments and tuning, and air spring bottom out tuning.

Tuning suggestions are starting points. It may take trying various adjustments to find the settings that work best for each individual rider, bicycle, and trail condition.

The Quarq ShockWiz suspension tuning device can be used for more detailed ride data analysis and setting suggestions. Go to sram.com/en/quarq for more information.

Rebound damping controls suspension rebound speed after compression.

Suspension rebound speed affects wheel contact with the ground, which affects control and efficiency. The suspension fork should rebound quickly enough to maintain wheel traction without feeling 'bouncy'. Too much rebound damping will not allow the fork to rebound quickly enough for the next bump.

• To increase rebound damping, and decrease rebound speed, rotate the knob clockwise.

• To decrease rebound damping, and increase rebound speed, rotate the knob counterclockwise.

Visit RockShox Trailhead for recommended starting rebound settings.

Rebound damping controls suspension fork extension/return speed which affects traction and control.

Optimal rebound damping allows the fork to extend at a controlled speed and maintain traction and control.

Rebound that is too fast allows the fork to extend too quickly which causes the wheel to bounce off of objects and the ground resulting in a 'pogo' effect.

Rebound that is too slow prevents the fork from extending quickly enough to regain contact with the ground or prepare for the next impact.

Rebound damping can be tuned to rider weight, spring rate and travel, as well as for terrain and rider preference.

As air pressure or spring rate increases, extension/return speed increases. To achieve the optimal setting, rebound damping may need to be increased when air pressure or spring rate increases.

For recommended rebound settings refer to RockShox Trailhead. After setting air pressure (DebonAir+) or sag, adjust the rebound damper, go for a test ride, and adjust again as preferred.

A: The fork rebounds at a controlled speed and the wheel maintains contact with the ground.

B: The fork crown, handlebars, and rider are more level with the ground over each bump. Suspension movement is predictable and controlled.

Adjustment: No adjustment is needed.
