3.  Wrap the chain whip around item 3 of the Zwift Cog, keeping the handle on the left-hand side.
4.  Place the lock ring bit tool into the lock ring and finger tighten—item 5.
5.  Turn the lock ring bit tool clockwise quarter of a turn to tighten—if you have a torque wrench, tighten to 5Nm.
    
    Be careful to not cross the threads when tightening the lock ring as this can cause serious damage.
    
6.  Remove the lock ring bit tool and you're good to go!

Ride On.
