After that, you will need to tighten the outer lockring.
ATTENTION Fixing the cassette on the freehub body is done by inner lockring. An outer lockring simply provides extra security and it has to be tightened with half the torque of the inner lockring.
BE CAREFUL since applying too much force when tightening the lockring may damage its threads and make it impossible to use the cassette properly.
Insert the outer lockring and screw it clockwise by hand until it’s securely tightened. Make sure the outer lockring is screwed correctly and tighten it with a removal tool to about 20 Nm torque.
