    I figured it out. had to insert cassette tool into cassette itself and the inner part turns. That's a new one for me.

    Can you please explain what you mean by "insert cassette tool into cassette itself"?
    I have tried putting the cassette tool on the outside of cassette like you would with a normal cassette but because of the teeth being engaged it wont let me tighten the cassette down.
    Thanks

    Ok place cassette tool into the actual cassette. The internal threads actually spin as cassette remains stationary. Just thread on and you are done

    This may help....

    When I got my XX1, I had trouble getting my older Park cassette tool to seat properly in the splines of the lock ring. In order to get proper engagement between the splines of the cassette tool and the lock ring, my friend milled out a few centimeters of metal from the cassette tool, which allows it now to sit deeper on the lock ring and engage the splines properly.

    I understand the newer generation of Park & Pedros cassette tools are machined differently , but those with older tools will likely have this issues with xx1.

    Just a helpful hint even though your issue is solved:

    If you didn't grease the treads/splines on your DT freehub body prior to installing your XX1 cassette, you might consider removing the cassette now, and greasing it before you ride it for the season. The threads/splines on the DT hubs are an incredibly close match, and if left ungreased, can make removing the cassette in the future extremely difficult. Enjoy!

    Here's my cassette removal story I posted on another forum (XX1 on DT Swiss). Hope it helps someone trying it for the first time...

    "Ha, you're not the first one to encounter this "issue". I've been meaning to do a post on it for a while, but was too lazy to get around to it. Short story is, this is common...

    The long story goes something like this:

    I had the same problem with the XX1 cassette on DT Swiss 240s hub. The reason is that the spline interface which transfers torque between the cassette and the freehub body is press fit, not loose fit like on Shimano. I think SRAM went with press fit because the splines are on the largest cog only, if the fit was loose the splines on the hub and maybe on the cassette would not last very long.

    First time I was removing the cassette, with one turn of the sleeve to go the thread started skipping with a very loud clang because the largest cog was still stuck and not moving. I used a piece of wood to give it a bit of a push. When it came off I noticed that thread skipping shaved off the last turn of thread off the free hub body - was not impressed at all.

    Second time I went to remove the cassette I was counting the turns of the spanner, with the piece of wood on stand-by for the last (5th) turn. To my horror, I noticed that because the largest cog was stuck while the sleeve was turning and trying to pull it off, the whole hollow cassette dome got stretched axially by several mm's. So I quickly backed off and after a second go the cassette popped off normally.

    Third time, I was trying to give the 42t cog a push after each turn of the spanner. This time the whole fckn free hub body flew off the hub axle with the cassette attached to it, and all the star ratchet bits went into the grass...

    At that point I switched from normal teflon grease to white lithium grease, and have had no issues since. Not sure if it's because of the different grease or because of wear and tear on the cassette/freehub body from regular removal..."

    centimeters

    That is a lot of machining

    I can't believe I am so bored I am trolling MTBR.

    I've run into problems installing on a 350 hub, the cassette (xx1) threads on, the splines engage and then after 2 turns it binds up like it's bottomed out on the end of the hub body. It still can rotate freely a few degrees between the splines, so it doesn't feel like it's hung up anywhere. I've installed before on a SRAM hub and it spun on smoothly. I already popped off part of the first thread trying to coax it on, now I'm contemplating my options. Both the hub body and cassette look fine, no obvious out-of -tolerance looking bits.

    Puzzled.....

    Thanks for sharing this.

    My old tool doesn't seat worth a $H*% and marred some of the splines. I will be updating my lockring tool hopefully with one that has a handle as well.

    Does anyone have experience with Pedros lockring tool with XX1 cassettes?
