Please refer to this manual if your XD-compatible cassette is a 2017 version (you can read about the differences between an updated version and previous one here)

Installation of SRAM XD driver body-compatible cassette requires tightening two different lockrings, so please refer to the installation steps below for installing the cassette you just purchased.

Tools you will need

One of the primary tools required for XD cassette installation is a lockring removal tool. We recommend using the kind of removal tool with guide pin that will not allow you to strip the lockring threads while tightening it.

Step 1

Clean the dust and mud from the freehub splines and threads.

Step 2

Remove the outer cassette lockring, unscrewing it in counter-clockwise direction. If necessary, hold the inner lockring with your hand.

Step 3

Put the cassette on the driver body splines. A cassette, unlike the freehub body, has key-less splines, and you can install it on the freehub in any position.

However, make sure to check whether the cassette is fitted securely and tightly on the splines. Misaligned cassette placement on the driver body may damage the cassette as well as the driver body.

Step 4

While holding the cassette, fully insert the lockring removal tool in the inner lockring threads and turn the removal to clockwise direction to about 40 Nm torque.

Step 5

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.

That's it!

After going through the steps described above the cassette is installed and ready for operation!
