SPRING SELECTION AND INSTALLATION: DBcoil Spring Selection
Selecting the appropriate spring rate is an important variable in achieving optimal set-up of the DBcoil. Your ideal spring rate will be based on rider weight, frame design, and riding style. (See our online calculator at canecreek.com or call the Cane Creek Service Team). Spring Removal and Installation To remove the spring, turn the Spring Adjustment Nut to remove all preload (the spring should become loose). Push down on the spring clip and slide it off the shock. Once the clip is removed, slide the spring off the shock. Certain frames require longer mounting hardware, it may be necessary to remove the mounting hardware from the end eyelet before the spring can be removed.
180 degrees apart
WARNING: Always make sure the end of the spring’s coil is aligned on the opposite side of the slot in the spring clip. An improperly oriented spring can fail prematurely, causing loss of vehicle control and SERIOUS INJURY OR DEATH.
SAG ADJUSTMENT: DBcoil

Spring preload is the compression applied to the spring by the Spring Adjustment Nut. The preload adjustment is used to fine-tune the optimal amount of sag to achieve proper ride height. Measuring and Setting Sag To achieve the best performance from your Double Barrel rear shock, the proper setting of sag is vitally important. As a starting point, we recommend a sag setting equal to 30% of available travel unless the frame manufacturer recommends otherwise. Sag is part of shock tuning, so you should experiment and vary your sag percentage to better suit your riding style and personal preferences. For example, if your style is more downhill, you can increase your sag percentage (by reducing preload) to add some plushness to your suspension. If your style is more all-mountain/XC, you can decrease your sag percentage (by increasing preload) to firm up your suspension. To Measure Sag 1 - Make sure that you are on a level surface. With the rear wheel off the ground, measure the length of your shock from eye-to-eye and record this measurement. 2 - Dressed to ride (including filled hydration bag, if you use one), position your bike next to a wall or table to support yourself. Mount your bicycle and assume your normal riding position. Measure the shock length again from eye-to-eye. You may need someone to assist in this measurement. Record this measurement.
SAG ADJUSTMENT: DBcoil 3 - The difference between the two measurements is the sag. %Sag = [(Free shock length - Weighted Length) ÷ Shock Stroke] x 100 Free Shock length: Measured in Step 1. Weighted Length: Measured in Step 2. Shock Stroke: Stroke is indicated on the spring that came with your DBcoil. If you are unsure of your shock’s travel, visit canecreek.com or contact the Cane Creek Customer Service Team. Increasing Spring Preload To increase the preload on your spring, turn the Spring Adjustment Nut clockwise. Increasing the preload will increase the ride height and reduce sag. This will result in a more responsive ride. Be careful not to apply too much preload (not more than 6 turns of the Spring Adjustment Nut) as this can cause “coil binding”, which can damage the spring, the shock, and can be dangerous for the rider.

SAG ADJUSTMENT: DBcoil
10
Reducing Spring Preload To reduce the preload on your spring, turn the Spring Adjustment Nut counter-clockwise. Reducing the preload will decrease the ride height and increase sag. This will result in a more plush ride. Do not reduce spring preload below 1 turn. The shock requires some spring preload to rebound properly.
IMPORTANT If more than 6 turns preload is needed to achieve proper sag, you will need to change to a stiffer (higher rate) spring. If less than 1 turn of preload is needed to achieve proper sag, you will need to change to a lower spring rate. For more information on adjusting your Spring Preload, view our suspension instructional videos online at canecreek.com.

Air spring preload is the amount of air pressure in the air chamber of the shock. The preload adjustment is used to fine-tune the optimal amount of sag to achieve the proper ride height. Measuring and Setting Sag To achieve the best performance from your Double Barrel rear shock, the proper setting of sag is vitally important. As a starting point, we recommend a sag setting equal to 30% of available travel. Sag is part of shock tuning, so you should experiment and vary your sag percentage to better suit your riding style and personal preferences. For example, if your style is more downhill, you can increase your sag percentage (by reducing air pressure) to add some plushness to your suspension. If your style is more all-mountain/XC, you can decrease your sag percentage (by increasing air pressure) to firm up your suspension. To Measure/Set Sag 1 - Attach high pressure shock pump to air valve and Inflate to ~50-75psi.
2 - Slowly cycle the shock. This will charge the negative air chamber.
SAG ADJUSTMENT: DBair 3 - Inflate shock to starting pressure, remove air pump. Slide travel indicating O-ring against air can.

5 - Sag = Distance from air can to O-ring Shock stroke = If you are unsure of your shock’s travel, visit canecreek.com or contact the Cane Creek Customer Service Team. %Sag = (Sag ÷ Shock Stroke] x 100. Make sure the shock pump is NOT connected to the DBair when measuring sag. When the proper sag value is reached, record the pressure required to achieve this sag value to make setup faster in the future.

Unique to bike suspension, the Double Barrel’s Twin-Tube Technology with 4-Way Independent Adjustment isolates both high-speed and low-speed rebound and compression circuits. This proprietary design allows for rider-tuned suspension, by providing an unsurpassed range of damper adjustment by simply turning external adjusters. Because these adjusters act completely independent of one another, adjustment of one will not affect the performance of another. Thus we invite you to DEFINE YOUR GREAT. Low-Speed Compression (LSC) Low-Speed Compression (LSC) controls traction and chassis stabilization. LSC adjustment is used to eliminate pedal induced “bob”, influences small bump sensitivity, and affects how the bike will react to weight changes. The Double Barrel decouples the LSC from the HSC (see HSC) so that the shock can address the aforementioned issues while still feeling supple and bottomless.
To increase the low-speed compression turn the LSC adjuster clockwise (screw in).
To reduce the low-speed compression damping, turn the LSC adjuster counterclockwise (unscrew).

High-Speed Rebound (HSR)
Low-Speed Rebound (LSR)
Low-Speed Rebound (LSR) Low-Speed Rebound (LSR) works with LSC to stabilize the chassis and manage traction. It is similar to the single rebound adjuster on most other rear shocks. Rider-tuned LSR adjustment (combined with LSC) ensures maximum traction everywhere from technical climbs, high-speed chatter, off-camber corners, to braking in stutter bumps.
To increase low-speed rebound, turn the LSR adjuster clockwise (screw in). To reduce the low-speed rebound, turn the LSR adjuster counterclockwise (unscrew).
TUNING ADJUSTMENTS: DBcoil | DBair

High-Speed Compression (HSC) High-Speed Compression (HSC) is critical to absorbing energy from high impact forces, such as square edge hits and harsh landings. When set properly, the highspeed compression (HSC) circuit allows the wheel to effectively absorb all impacts without harshly bottoming out or using too much travel.
To increase high-speed compression, turn the HSC adjuster clockwise (screw in).
To reduce high-speed compression, turn the HSC adjuster counterclockwise (unscrew).
High-Speed Rebound (HSR) An adjustment unique to the Double Barrel, High-Speed Rebound (HSR) enables a bike to recover quickly from deep in suspension travel while enabling controlled takeoffs from jump faces. By giving the rider independent control of HSR and LSR, bucking (a high shaft-speed problem) can be eliminated while allowing the shock to recover quickly to prevent packing up (a low shaft-speed problem).
To increase high-speed rebound, turn the HSR adjuster clockwise (screw in).
To reduce high-speed rebound, turn the HSR adjuster counterclockwise (unscrew). Note: when turning HSC the LSC adjuster will turn with HSC adjuster, DO NOT hold the LSC adjuster when turning the HSC adjuster.

To enjoy the full benefits of your Double Barrel shock, it is important that your shock is tuned specifically to your bike and riding style. The Symptoms section below will help you find your own ideal settings to Define Your Great. As a general rule, use the following order to adjust your shock: 1 Verify correct sag. For additional assistance, see the relevant sections for Adjusting Sag. 2 On a familiar trail, fine tune Low-Speed Compression (LSC) and Low-Speed Rebound (LSR) to suit your preferences for resistance to pedaling induced chassis motion and traction. For additional assistance, see the Symptoms listed. 3 Adjust High-Speed Compression (HSC) so that all the travel is occasionally used, but no harsh bottom out is felt. For additional assistance, see the Symptoms listed. 4 Adjust High-Speed Rebound (HSR) to prevent bucking. For additional assistance, see the Symptoms listed. No shock adjustments should be made without first setting sag properly. Failure to do so will lead to incorrect damper adjustments.
TUNING TIPS: DBcoil

Symptom: Shock is harshly bottoming out. Causes: Incorrect spring rate and/or insufficient high-speed compression (HSC). Remedy: First confirm that your spring rate is correct, so that proper sag is achieved. See page 8 for details. Next, increase (clockwise) high-speed compression (HSC) until no harsh bottoming out is experienced while full travel is being used. Symptom: Bike wallows under pedaling (pedal bob); overall ride is too soft. Causes: Not enough low-speed damping. Remedy: Increase (clockwise) both low-speed compression (LSC) and low-speed rebound (LSR) to slow the movement of the suspension. Symptom: Shock is harsh over chatter, braking bumps, and square edge hits. Causes: Spring rate too high and/or too much high speed compression (HSC). Remedy: First confirm that your spring rate is correct, so that proper sag is achieved. See page 8 for details. Next, decrease (counterclockwise) high-speed compression damping (HSC) until harshness is removed. If symptoms persists with HSC fully counterclockwise, gradually decrease LSC (counterclockwise). Symptom: Rear end is bucking upon impacts, bike is nose-diving when jumping. Causes: Not enough high-speed rebound (HSR). Remedy: Increase (clockwise) high-speed rebound (HSR) until rear wheel rebounds properly from deep in travel.

Note: In the following symptoms, there is a difference between air volume and air pressure. Air pressure is changed with the shock pump. Air volume is changed by adding/ removing the included air volume adjustment spacers. Symptom: Shock is harshly bottoming out. Causes: Insufficient high-speed compression (HSC) and/or incorrect air volume setting. Remedy: Increase (clockwise) high-speed compression (HSC) until no harsh bottoming is experienced but full travel is being used. If enough HSC is required that the ride becomes harsh, you may need to modify your air volume using the included air volume adjustment spacers. For instructions on how to do this, go to www.canecreek.com. Symptom: Bike wallows under pedaling (pedal bob); overall ride is too soft. Causes: Not enough low-speed damping. Remedy: Increase (clockwise) both low-speed compression (LSC) and low-speed rebound (LSR) to slow the movement of the suspension. Symptom: Shock is harsh over chatter, braking bumps, square edge hits. Causes: Too much high speed compression damping (HSC) and/or incorrect air volume setting. Remedy: Decrease HSC (counterclockwise) until harshness is removed. If HSC is fully counterclockwise but the harshness remains, you may need to modify your air volume using the included air volume adjustment spacers. For instructions on how to do this, go to www.canecreek.com. Symptom: Rear end is bucking upon impacts, bike is nose-diving when jumping. Causes: Not enough high-speed rebound (HSR).

Cane Creek Double Barrel rear shocks are designed for long-term durability, though some simple maintenance steps can ensure long-life and smooth function. IMPORTANT NOTES
Do not use compressed air to clean any Double Barrel shock.
Do not use any solvents or de-greasers, as these products can damage the shock’s exterior finish or its anodized parts.
Do not spray water directly at any seal. Never use a high pressure washer on your rear shock.
When dirt dries onto the shock body, it may damage seals. With a damaged seal, dirt works its way into the shock and can hinder performance and cause damage. Simple, periodic maintenance can greatly extend the service life of your shock. If you ride in extreme weather conditions, the service intervals should be more frequent. Check for any oil leaks. If you are unsure if there is a leak or simply a seepage of assembly grease, proceed with the cleaning steps below and recheck the suspect area after riding. Before every ride, check that the mounting hardware is tight and ensure there is no play between the Norglide® bushing and the mounting hardware. For cleaning, use mild soapy water, a very light pressure water spray to rinse, and wipe dry with a clean, dry cloth.
