Ceramicspeed OSPW X Guide

Mounting &
Maintenance
OSPW X
For SRAM Eagle Mechanical and AXS

Maintenance
No set of rules can be made for how often your Oversized Pulley Wheels are
to be maintained. Maintenance frequency depends on the weather conditions
that you are riding in.
A worn chain will increase the wear on the pulley wheels significantly, so
make sure that you change your chain before it is completely worn out. Under
normal conditions, we recommend that you service the Oversized Pulley
Wheels when you have ridden under wet conditions, washed your bike or each
time you lubricate the chain. For normal maintenance, add a drop of oil into
the lubrication points (see the page 3) for optimal performance. Make sure
to position the OSPW System horizontally to ensure that the oil reaches the
Oversized Pulley Wheel bearings.
We recommend the use of CeramicSpeed Oil on the OSPW System. This can
be purchased from the CeramicSpeed dealers worldwide or from our webshop.
Watch our maintenance video on ceramicspeed.com in the Support section.
When travelling, your OSPW System will not fit in the bike travelling bag. We
recommend that you dismount the whole rear derailleur and pack it aside.
Extended Maintenance
Approximately once every half a year we recommend that you perform an
extended maintenance. In this case, you should dismount the Oversized Pulley
Wheels from the cage, remove the seals from both sides and clean all parts in
a shaker with degreaser. After cleaning, dry the components off, put two drops
of oil onto the CeramicSpeed Balls, place the seals back on and remount
the Oversized Pulley Wheels. When dismounting the cage plates, you will
need a 2.5 mm Allen Key for the pulley wheel bolts (see page 3) and a 2 mm
Allen key for the tower bolts. To remount the screws, tighten the pulley wheel
screws up to a max torque of 1 Nm and the tower bolts up to 0.3 Nm. For this,
a torque tool is recommended. If you’re riding in wet and muddy conditions , we
recommend you to perform an extended maintenance more frequently and
replace oil with All Round Grease for better protection.

Derailleur compatibility
The OSPW X cages fits all Eagle derailleurs regardless of the cage length.
The cage compatibility is specific to either mechanical derailleurs, or a
separate system for Eagle AXS derailleurs. The installation and setup
is slightly different between the mechanical and AXS systems, these
differences are called out below.
Cassette sizes
OSPW X is compatible for 1052 tooth cassettes.
ATTENTION
To guarantee the best possible shifting performance with the OSPW X you
must ensure that the cable & housing is setup correctly per the original
manufacture’s specification. Poor cable performance and/or housing
routing from the shifter to the derailleur can impede accurate derailleur
actuation.

To ensure the very best in riding performance it is vital that your new
OSPW X System is mounted correctly. Follow these instructions to install your
OSPW X System for SRAM Eagle Mechanical and AXS:
1. Begin with your bike mounted in a stand.
Shift up 23 gears.
2. Remove the chain and the rear wheel.
4. Hold the cage and release the cage
lock, and unwind the cage 360° (counter
clockwise seen from front of rear derailleur)
to release the spring tension.
3. Rotate the stock pulley cage forward and
engage the Cage Lock. Remove the stop
screw with a 3mm Allen Key, this will not
be reused.
Mounting Manual

7. Unbox the OSPW and remove the silver
CeramicSpeed stop screw with a 2,5mm
Allen key (to be reused). For the AXS
system, take note of the replacement
mounting bolt to complete installation.
6. Remove the plastic cap if it did not come
off with the derailleur cage and set aside
(Not to be used with OSPW X). You should
now see the pulley cage tension spring.
8. There are 3 holes for spring tension.
We recommend Medium tension setting
(marked ‘M’ at the interface) to minimize
drive train friction & provide necessary
chain tension.
Please move the spring tension to ’H’
(high) if you experience any issues such
as slow shifting response or repeatedly
drop a chain.
5. Loosen the original main mounting screw
with a 3mm Allen key and remove the
original cage.
You will reuse the factory cage mounting
screw for the mechanical system. For the
AXS system you will use a new, included,
mounting bolt.

11. Recommendation on upper pulley clearance
on the largest cog (adjusting of B-limit) =
15mm.
You may reuse the existing chain if desired &
the chain is still in good condition.
For a new chain installation, please follow the
chain length guide below:
10. Turn the cage clockwise (seen from front of
rear derailleur) and increase the spring tension
and secure the cage with the Cage Lock.
Install the CeramicSpeed stop screw with a
2,5mm Allen key (torque to 3Nm).
9. Once the spring tension setting is selected,
align the OSPW X, spring and derailleur body
together.
Mechanical and AXS GX: Install the factory cage
mounting bolt and torque to 4Nm*.
AXS XX1 and X01: Install the included Ceramic-
Speed mounting bolt and torque to 4Nm*.
Rotate the cage back and forth to ensure a
smooth movement without binding.
*In rare circumstances, you may need to access the
clutch from the face of the derailleur to secure the
cage bolt to 4nm. To do this, remove the outer clutch
cover on AXS derailleurs by removing the phillips
screw located on the back of the derailleur body next
to the main body spring. For mechanical derailleurs,
continue to the next step. Next, remove the inner
clutch cover with a T25 torx, providing access to the
clutch and hold stable with a 4mm allen key. Once the
cage is secured, reassemble the clutch covers.

If you are using a 44 tooth or larger chain ring you may not be able to overlap
the ends of the chain for measurment. You do not need to add any links to a
stock chain, a full length chain is sufficent for use.
Recommendation on upper pulley clearance on the largest cog (adjusting of
B-limit) = 1015mm depending on cassette size.
Chain length
STEP 1: Place the chain on the smallest cog on the cassette. To find the
correct chain length, pull the two chain ends together, just as you would
when needing to cut a chain to length. The lower part of the cage should
start to move downwards, away from the cassette, as referenced in the
second image.

STEP 3: With the chain now cut to length it is important to test the clearance
of the OSPW X System when the rear derailleur is set in the largest cog on
the cassette. Just as the arrow indicates the cage should be able to rotate
counter clockwise. It is important that there is some clearance between
the upper pulley wheel of the OSPW X System and the largest cog on the
cassette. If you find the clearance is not enough, adjust the B-tension
accordingly.
STEP 2: When tension is applied on the chain and the OSPW X System
appears to be aligned as the diagram above, the chain needs to be cut
(1 link shorter than step 1) and connected by the required amount of links
in order to achieve sufficient tension in this gear combination (always the
small cog on the cassette).
1 link shorter
than step 1
