ceramicspeed 11 Tooth Pulleys for Shimano 12 Speed Dura Ace 9250
INSTALLATION
- For Dura Ace 9250 deraillurs, place the round center bushing inside each pulley bearing as shown.
- For Ultegra 8150 and 105 7150 derailluers, place the flanged spacers on both sides of each pulley bearing as shown.
- To install, remove the upper pulley bolt, and set aside the pulley and dust shields. Place the CeramicSpeed pulley marked ’upper’ and a clockwise rotational arrow with the etching facing away from the wheel and replace the stock pulley bolt to a torque of 3Nm. Repeat the process for the lower pulley, showing a counter-clockwise rotational arrow, with the etching facing away from the wheel. Both arrows should rotate forward when the drivetrain is pedaled forward.
Maintenance
No set of rules can be made for how often your 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 Pulley Wheels when you
have ridden under wet conditions, washed your bike or each time you lubricate
the chain. For normal maintenance, add a few drops of oil along the edge of
each bearing while slowly rotating the drivetrain/pulleys. We recommend the
use of CeramicSpeed Oil on the pulley bearings. This can be purchased from the
CeramicSpeed dealers worldwide or from our webshop. Watch our maintenance
video on ceramicspeed.com in the Support section.
Extended Maintenance
Approximately once every half a year depending on the conditions, we recommend
that you perform an extended maintenance. In this case, you remove the pulleys
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 reinstall the
pulleys. If you’re riding in wet and muddy conditions, we recommend you
perform an extended maintenance more frequently and replace oil with All Round
Grease for better protection.
