SAFETY INSTRUCTIONS
Always wear safety glasses and nitrile gloves when working with grease and Reverb™ hydraulic fluid.
Do not allow Reverb hydraulic fluid to come into contact with disc brake levers, calipers, pads, rotors, or braking surfaces. If Reverb hydraulic fluid
contacts brake pads, the brake pads must be replaced. Use isopropyl alcohol to remove Reverb hydraulic fluid from any brake or braking surface.
Failure to remove Reverb hydraulic fluid from brakes and braking surfaces can damage components and reduce brake performance, and may result in
serious injury and/or death to the rider. Remove all brake components before performing the hose removal and installation, and the hydraulic remote
bleed processes.
Place an oil pan under the RockShox® product during service.
NOTICE
Before you begin the service process, thoroughly clean the exterior of the product to prevent contamination of internal parts.
Use soft jaw vise inserts to prevent damage to a part that is clamped into a vise. Clamp each part just tight enough to prevent it from rotating in the
soft jaws.
Install a crowfoot socket at 90 degrees to the torque wrench to ensure an
accurate torque value.
Use isopropyl alcohol and a clean rag to clean each part before you install
new seals.
Do not scratch any part with a sealing surface. Inspect each part for
scratches. Scratches can cause leaks and degrade product performance. Any
part with a scratch on a sealing surface must be replaced.
Apply only SRAM® Butter grease to Reverb parts, seals and o-rings.

12Seatpost Removal
Use a 4mm hex wrench to remove the saddle clamps and saddle from
the seatpost.
Use a 9mm socket to remove the air cap from the post head.
Use a small hex wrench or pick to depress the Schrader valve and
release all air pressure from the air chamber.
⚠ WARNING EYE HAZARD
Verify all pressure is removed from the seatpost before proceeding.
Failure to do so can cause the inner seal head and inner shaft to
separate from the upper post assembly at high velocity during
disassembly. Wear safety glasses.
Use a wrench, or quick release lever, to loosen the seatpost collar.

13Seatpost Removal
Remove the seatpost from the bicycle seat tube while simultaneously
pushing the hydraulic hose into the hose port in the bicycle frame.
The hose port location will vary depending on the bicycle frame.
Consult with your frame manufacturer for additional information.
NOTICE
Do not pull the seatpost out of the frame if there is tension at the hose.
This can cause damage to the hydraulic hose and hose barb.
Clamp the seatpost into a bicycle work stand to hold it in position.
Place a rag under the seatpost and hose to absorb any hydraulic fluid
that may drip when the hose is disconnected.
To continue with the bleed procedure proceed to Hydraulic Remote
System Bleed.

14Hydraulic Hose Disconnect
50/200/400 Hour Service
Hydraulic Hose Disconnect
Reverb™ Stealth is available with one of two hydraulic hose assembly types: 1) Hose barb, and 2) Connectamajig™. For Connectamajig hose
assemblies, either the Connectamajig coupler can be removed from the seatpost, or the Connectamajig hose coupler can be removed from the
Connectamajig coupler.
The hydraulic hose must be disconnected from the seatpost for all service procedures. Follow the procedure below for the hose type on your
Reverb Stealth.
The hose does not need to be disconnected from the remote lever for seatpost service.
⚠ WARNING
Do not allow Reverb hydraulic fluid to come into contact with any brake components. Contaminated brake components can compromise brake
performance, may cause brake failure, and can lead to serious injury and/or death.
Disconnect the hydraulic hose from the seatpost. Use a rag to wipe
away any hydraulic fluid.
Hose Barb: Use a 10 mm and a 7 mm open end wrench to unthread
and remove the hose barb and hose assembly from the poppet cover.
Connectamajig Hose Coupler (option 1): Use a 9 mm and a 6 mm
open end wrench to unthread and remove the hose coupler from
the Connectamajig coupler. Service can be performed with the
Connectamajig coupler installed.
Connectamajig Coupler (option 2): Use a 10 mm and an 8 mm open
end wrench to unthread and remove the Connectamajig coupler from
the poppet valve cover.

Lower Post Removal
NOTICE
Use bench vise soft jaw inserts to prevent damage to the seatpost or any seatpost component when clamping it into a vise. Clamp each component
only tight enough to prevent it from spinning in the soft jaws. To prevent the part from slipping, clean the vise soft jaw inserts with isopropyl alcohol
and a clean rag before use.
Clamp the lower post of the seatpost into a bench vise and
Park Tool® AV-5 soft jaw vise inserts, with the post head facing down.
Use a pick to rotate the retaining ring so the scalloped end is
accessible with the pick. Use the pick to pry the retaining ring out of
the groove. Slide the pick around the rim of the lower post to pry the
retaining ring from the lower post.
Push the upper post up to expose the poppet valve housing base plate
lockring.
Use an 11 mm open end wrench and a 26 mm, or adjustable, open end
wrench to remove the lockring from the poppet valve housing.
