SRAM XD cassette wobble?
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?Posted 3 years ago
I also noticed that on the 10T cog the chain is really really close to the frame.Posted 3 years ago
It’s probably not tight enough. I had similar, and if its a new install you need more force than you think to tighten things up. 40NM is a fair swing on a 300mm long torque wrench, as I discovered.Posted 3 years ago
I had this same issue with XD driver and a gx cassette on a new bike. Turns out it had been cross threaded so was replaced under guarantee. Perhaps the design is prone to misalignment during installation? Can you post a photo ?Posted 3 years ago
Unfortunately I don’t have a torque wrench. I’m using an open end wrench (with a cassette tool) that’s about 25cm long but I can’t tighten the cassette any more.
Will post pics tomorrow. I’m 99.9% sure it’s not cross threaded, all the threads look perfect, no metal shavings anywhere.Posted 3 years ago
The other option, as I have just been through this is the free hub may be cracked but most likely is you need to nip it up properly. This will also go some way to increasing the chain / frame clearance on the 10 cogPosted 3 years ago
Just had the same issue. Turns out you need to lube the freehub body / inside of cassette with chain lube to get it to slide fully onto the freehub.
If you dont do this and torque it up, you get a faslse torque as it’s not seated properly and therefore the play you are describing.

Thanks a lot aldo56! I was starting to get worried.
I didn’t have any penetrating or super thin oil, only thicker stuff, but I did lube the mechanism and it helped a lot. It’s still not a 100% perfect, but it’s pretty damn close.Posted 3 years ago
Will try to get some thinner stuff and do it again.
