Hold the back brake (or hold it in place with a zip tie)

So the back wheel cant move, and the carbon belt holds the chain ring in place

with the Bosch chain ring lock ring removal tool on a 1/2" ratchet loosen the lock ring on the chain ring

To loosen one needs to turn it to the right! (clockwise) [it is the opposite direction than usual]

A significant force is needed to loosen the lockring

In a later step, after the carbon belt is removed, the chain ring can easily be pulled down too

The text must face outwards both on the chainring and the lockring
