To ensure the very best in riding performance it is vital that your new  

OSPW System is mounted correctly. Follow these instructions to install your 

OSPW Aero and SRAM Red/Force AXS:

1.

  

Begin with your bike mounted in a stand.

 

Shift the derailleur up so that the cage can 

rotate past the body. Remove the rear wheel.  

2.

  

Remove the rear derailleur from the bike. 

Remove both pulley wheels and the back half 

of the pulley cage.

4.

  

Remove the main center nut and the stock 

cage. There will be a small amount of spring 

tension on the cage due to the clutch.  

Set aside the spring and center nut for 

reuse. 

3.

  

Hold the stock pulley cage (not just the 

derailleur) and loosen the main center nut 

with the CeramicSpeed special tool but do not 

completely remove the mounting nut. 

When the center nut is loose enough, allow 

the rotation stop screw to move past the stop 

point on the derailleur body to release the 

spring tension.
