4RockShox Service
RockShox Service
We recommend that you have your RockShox suspension serviced by a qualified bicycle mechanic. Servicing RockShox suspension requires knowledge of
suspension components, as well as the use of specialized tools and lubricants/fluids. Failure to follow the procedures outlined in this service manual may
cause damage to your component and void the warranty.
Visit www.sram.com/service for the latest RockShox Spare Parts catalog and technical information. For order information, please contact your local SRAM
distributor or dealer.
Information contained in this publication is subject to change at any time without prior notice.
Your product's appearance may differ from the pictures contained in this publication.
For recycling and environmental compliance information, please visit https://www.sram.com/en/company/about/environmental-policy-and-recycling.
Part Preparation
Remove the component from the bicycle before service.
Disconnect and remove the remote cable or hydraulic hose from the fork or rear shock, if applicable. For additional information about RockShox remotes,
user manuals are available at www.sram.com/service.
Clean the exterior of the product with mild soap and water to avoid contamination of internal sealing part surfaces.
Service Procedures
The following procedures should be performed throughout service, unless otherwise specified.
Clean the part with isopropyl alcohol or RockShox Suspension Cleaner and a
clean, lint-free shop towel. For hard to reach places (e.g. upper tube, lower leg),
wrap a clean, lint-free shop towel around a non-metallic dowel to clean the inside.
Clean the sealing surface on the part and inspect it for scratches.
Replace the o-ring or seal with a new one from the service kit. Use your fingers or
a pick to pierce and remove the old seal or o-ring.
Apply grease to the new seal or o-ring.
NOTICE
Do not scratch any sealing surfaces when servicing the product. Scratches can
cause leaks. Consult the spare parts catalog to replace the damaged part.
Use aluminum soft jaws when placing a part in a bench vise.
Tighten the part with a torque wrench to the torque value listed in the red bar.
When using a crowfoot socket and torque wrench, install the crowfoot socket at
90 degrees to the torque wrench.
Specified torque value in N·m (in-lb)

Travel Change Adjustment - Optional
To increase or decrease the travel in your Reba or Bluto fork, the air spring must be replaced with the correct length air spring shaft assembly. Refer to the
RockShox Spare Parts Catalog available on our website at www.sram.com/service for spare part kit details.
Bottomless Token - Optional Installation
Bottomless Tokens can be added to, or removed from, the air top cap to fine-tune the bottomout feel and spring curve. Bottomless Tokens reduce the air
volume in your fork to create greater ramp at the end of the fork travel. Add tokens to maintain your fork's bottomless feel.
Thread a Bottomless Token into another token or into the bottom of the
top cap.
