I just bought a SRAM Rival 1 groupset. It came with a XG-1150 cassette. This is my first time ever installing an XD cassette. I greased both the inside of the cassette and the freehub body itself, then simply tightened the cassette onto the freehub body.
The problem is, the larger cogs (and probably the whole cassette) wobbles side to side, it’s “out of true” about a good 2-3mm. It’s not freehub wobble, it does it when i’m pedalling.
At first I thought I cross threaded it, but I took off the cassette and the threads look immaculate.
Is this normal, or did I do anything wrong?
