Air Spring Travel Change and Bottomless Tokens™ (optional)

To increase or decrease the travel in your RockShox® Sektor™, an All-Travel spacer can be installed or removed. For example, to increase travel from a maximum of 130 mm of travel to a maximum of 150 mm of travel, the 20 mm All-Travel spacer must be removed from the air spring assembly. If travel is changed from 80 mm, 100 mm, or 120mm to 130 mm, 140 mm, or 150 mm, and vice versa, the air spring must be replaced with the appropriate length air spring assembly in addition to the appropriate length All-Travel spacer. Use the table and images below to determine which All-Travel spacer and air spring assembly can be used with each fork travel option.

Bottomless Tokens can be added to, or removed from, the DebonAir™ top cap to fine-tune the spring curve and bottom out feel. Use the table below to help determine the number of Bottomless Tokens that can be used with each fork travel option. If fork travel is changed from stock, it may be necessary to add or remove Bottomless Tokens.

Refer to the RockShox Spare Parts Catalog at www.sram.com/service for available air spring, All-Travel spacer, and Bottomless Token kits.

Scratches on the shaft can cause oil to leak. If a scratch is visible, the rebound damper may need to be replaced.

Damper Service

Remove the inner and outer seal head o-rings and discard them.

Apply grease to the new o-rings and install them.

Remove the glide ring and discard it.

Install a new glide ring.

Damper Service

Install the seal head onto the rebound damper shaft.

Rebound Damper Installation

200 Hour Service Rebound Damper Installation

Insert the rebound damper piston and seal head into the upper tube.

Push the seal head into the upper tube until the retaining ring groove is visible.

Push the rebound damper into the upper tube and thread a bottom bolt into the shaft.

Retaining rings have a sharper edged side and a rounder edged side. Installing retaining rings with the sharper edged side facing the tool will allow for easier installation and removal.

Install the retaining ring into the upper tube groove.

NOTICE

Do not scratch the rebound damper shaft. Scratches will allow oil to leak into the lower leg, resulting in reduced damping performance.

⚠ CAUTION

Confirm the retaining ring is properly seated in the retaining ring groove by using the retaining ring pliers to rotate the retaining ring and seal head back and forth a few times.

Pull the rebound damper shaft out to the fully extended position and remove the bottom bolt.

Compression Damper Installation

200 Hour Service Compression Damper Installation

Pour 130 mL of RockShox® 5wt suspension oil into the upper tube.

NOTICE

Suspension oil volume is critical. Too much oil reduces available travel and can damage the fork. Too little suspension oil decreases damping performance.

RL: Use the compression adjuster knob to open the valve (A). Rotate the knob counter clockwise until it stops.

A closed compression valve will restrict oil flow during installation.

Insert the compression damper into the upper tube. Press down slowly and rotate in a circular motion until the damper is installed.

Lower Leg Installation

Refer to your pre-service recorded settings, or use the air chart on the fork's lower leg, and pressurize the air spring.

You may see a drop in the indicated air pressure on the pump gauge while filling the air spring; this is normal. Continue to fill the air spring to the recommended air pressure.

Compressing the fork will equalize the positive and negative air chambers. After the fork is cycled 3-4 times, check the pressure and add air as needed.

Install the air valve cap.

Clean the entire fork.

This concludes the service of your RockShox® Sektor™ suspension fork.
