When replacing o-rings, use your ﬁngers or a pick to remove the o-ring. Clean the o-ring groove and apply grease to the new o-ring.

5ROCKSHOX SUSPENSION SERVICE

LOWER LEG REMOVAL

1 Remove the air valve cap from the top cap located on the

non-drive side fork leg.

2 Use a small hex wrench to depress the Schrader valve and release

all of the air pressure from the air chamber.

Use a Schrader valve tool to remove the valve core from the valve

body. Install a new Schrader valve.

CAUTION- EYE HAZARD

Verify all pressure is removed from the fork before proceeding.

Failure to do so can result in injury and/or damage to the fork.

3 Remove the external rebound adjuster knob by pulling it from the

shaft bolt at the bottom of the drive side fork leg.

4 Use a 5 mm hex wrench to loosen both shaft bolts 3 to 4 turns.

5 mm

6LOWER LEG REMOVAL

5 Place an oil pan beneath the fork to catch any draining ﬂuid.

Insert a 5 mm hex wrench into the one of the shaft bolts. Use a

plastic mallet to ﬁrmly strike the wrench and free the bolt from the

lower leg. Remove the shaft bolt from the lower leg. Repeat this

procedure for the other shaft bolt.

6 Firmly pull the lower legs downward until ﬂuid begins to drain.

Remove the lower leg from the fork by pulling it downward,

holding onto both legs or the brake arch.

If the lower legs do not slide out of the upper tubes or if ﬂuid

doesn’t drain from either side, the press ﬁt of the shaft(s) to the

lower leg may still be engaged. Reinstall the shaft bolts 2 to 3 turns

and repeat the previous step.

NOTICE

Do not hit the brake arch with any tool when removing the lower

leg as this could damage the fork.

7 Spray isopropyl alcohol on the inside and outside of the lower leg.

Wipe the outside of the lower leg with a rag.

Wrap a rag around a long dowel and insert it into the lower leg to

clean the inside of each lower leg.

5 mm

7LOWER LEG REMOVAL

LOWER LEG SEAL SERVICE

1 Place the tip of a downhill tire lever underneath the lower lip of the

dust wiper seal.

NOTICE

If using a ﬂat head screwdriver, make sure it has a round shaft. A

screwdriver with a square shaft will damage the fork leg.

2 Stabilize the lower legs on a bench top or on the ﬂoor. Hold the

lower legs ﬁrmly and use downward force on the tool handle to

leverage the dust wiper seal out. Repeat on the other side.

NOTICE

Keep the lower leg assembly stable. Do not allow the lower legs

to twist in opposite directions, compress toward each other, or

be pulled apart. This will damage the lower leg.

3 Use your ﬁngers to remove and discard the foam rings inside the

lower legs.

4 Soak the new foam rings in RockShox 15wt suspension ﬂuid.

Reinstall new foam rings on the top bushings in the lower legs.

8LOWER LEG SEAL SERVICE

5 Use a seal installation tool to install the new dust wiper seals.

Position the dust wiper into the recessed side of the tool, so the

grooved side of the seal is visible.

6 Hold one of the lower legs and use the seal installation tool to push

the dust wiper seal evenly into the lower legs until there is no gap

between the dust wiper seal and lower legs.

SOLO AIR SPRING SERVICE

OPTIONAL TRAVEL CHANGE ADJUSTMENT

To change the travel in your suspension fork, replace the entire solo air spring assembly according to the directions below. For part

number information, please refer to the Spare Parts Catalog available on our website at sram.com/service. For ordering information,

please contact your local SRAM distributor or dealer.

SOLO AIR SPRING REMOVAL

1 Use a small hex wrench to depress the Schrader valve and release

all of the air pressure from the air chamber.

CAUTION- EYE HAZARD

Verify all pressure is removed from the fork before proceeding.

Failure to do so can result in injury and/or damage to the fork.

2 Use a 24 mm socket wrench to remove the air spring top cap.

Once removed, clean the upper tube threads with a rag.

3 Use a pick to remove the top cap o-ring. Apply a small amount of

grease to a new top cap o-ring and install it. Apply a small amount

of grease to the top cap threads.

Do not scratch the top cap. Scratches can cause leaks.

24 mm

10 SOLO AIR SPRING SERVICE

4 Use a pick to remove and replace the air valve cap o-ring.

5 Place the tips of large internal snap ring pliers into eyelets of the

snap ring, located at the bottom of the non-drive side upper tube.

Press ﬁrmly on the pliers to push the air shaft guide into the upper

tube enough to compress and remove the snap ring.

Guide the snap ring over the air shaft to prevent scratching.

Scratches on the air shaft will allow air to bypass the seal head

into the lower legs, resulting in reduced spring performance.

6 Firmly pull on the air shaft to remove the air shaft assembly from

the upper tube. Clean and inspect the assembly for damage.

11 SOLO AIR SPRING REMOVAL

7 Spray isopropyl alcohol on the inside and outside of the upper

tube. Wipe the outside of the upper tube with a clean rag.

Wrap a rag around a long dowel and insert it into the upper tube

to clean inside the upper tube.

8 Remove the ﬂoating seal head, washers, ﬂoating seal head topout

bumper, and air shaft guide from the air shaft.

Spray isopropyl alcohol on the air shaft and clean it with a rag.

9 Use a pick to remove the inner and outer ﬂoating seal head o-rings.

Inspect the seal head for scratches. Spray isopropyl alcohol on the

seal head and clean it with a rag.

Apply a liberal amount of grease to the new o-rings and install

them.

Do not scratch the ﬂoating seal head. Scratches can cause leaks.

10 Use a pick to remove the air piston outer o-ring.

Inspect air piston for scratches. Spray isopropyl alcohol on the air

piston and clean it with a rag.

Apply a liberal amount of grease to the new o-ring and install it.

Do not scratch the air piston. Scratches can cause leaks.

12 SOLO AIR SPRING REMOVAL

11 Use your ﬁngers to remove the bumper cone from the air shaft.

Install a new bumper cone onto the air shaft so it covers the

tension pin hole.

NOTICE

If the pin tension is protruding or not centered, replace the piston

assembly.

SOLO AIR SPRING INSTALLATION

1 Apply a liberal amount of grease to the inside of the upper tube,

from the end of the tube to approximately 60 mm into the tube.

2 Apply a liberal amount of grease to the air piston.

3 Apply a liberal amount of grease 40-60 mm around the air shaft.

Install the ﬂoating seal head, a new ﬂoating seal head topout

bumper, new aluminum support washer, new wavy washer and the

air shaft guide, in that order, onto the air shaft.

13 SOLO AIR SPRING INSTALLATION

4 Firmly push the air assembly into the bottom of the upper tube

while gently rocking the air shaft side to side.

Orient the washers so that the aluminum support washer goes into

the upper tube ﬁrst, followed by the wavy washer.

5 Install the snap ring onto internal snap ring pliers. Use the pliers to

push the air shaft into the upper tube while installing the snap ring

into its groove. The air shaft guide should be situated between the

snap ring eyelets.

Make sure the snap ring is securely fastened in the snap ring

groove. Check this by using the snap ring pliers to rotate the

snap ring back and forth a couple of times, then ﬁrmly pulling

down on the air shaft.

Snap rings have a sharper-edged side and a rounder-edged side.

Installing snap rings with the sharper-edged side facing the tool

will allow for easier installation and removal.

6 Insert the top cap into the top of the upper tube. Use a torque
