    xt 11spd m8000 doesnt fit stan's hubs

    As of now the xt m8000 cassette does not fit onto the stans 3.30 hub bodies. Stans hubs appear to be a bit larger probably to make up for the slop from factory cassettes. Shimano decided to tighten up the large carrier probably due to the huge 42T cog.

    2 instances. My own and another. Might be specific to 3.30 hubs though. I should have been specific. The smaller cog carrier slid right on.

    Ztr's not 3.30 hub? I'll have to check before purchase.

    I have the 3.3o hubs on Flow Ex rims. I'm running a xt m8000 11x42t cassette. Fit is perfect.

    What did Stans say when you contacted them about this?

    Are you talking about the splines on the freehub? They're taller or wider? I'm sure Stan's didn't make any changes - the hubs come from one of the major hub factories in china or taiwan.

    Something don't smell right here. There has to be a logical explanation.

    Until I switched over to Hope hubs a couple months ago, the new 11spd M8000 cassette was a perfect fit on my 3.30 hub.

    The issue may be a variance in the XT8000 large carrier. On a new Easton carbon wheel all of the cogs & carriers fit loose on the free hub, the large cog carrier was too tight to even slide on 1mm. I then tried an XTR 9 sp & XT 10 sp cogset, both slide on on the loose side. I then contacted a buddy who just fit XT 8000 on his Easton free hub - his slide on with no issues. I then put the carrier in the oven and the freehub in ice and greased the free hub splines. 30 minutes later it slide on, but it was a snug fit. Greasing the splines should help when it comes time to remove it.

    Not sure where you get this idea from ... but my XT m8000 fits perfectly fine on the 3.30 (and it fits perfectly fine when I installed a One Up 45). I don't see why it would not, given that the dimensions of the cassette are unchanged ...

    So I sent back the cassette and ordered another M8000 from a different vendor. This cassette took some influence (mallet and a large socket) to get about a third of the way on and then it slip fit the rest of the way on. My conclusion based on my experience is that their is a conflict with tolerances going on. I tried about 5 other 9 nd 10 speed cassettes I had laying around and they all went right on no problem as well as both of the next smallest carriers on the 2 M8000 cassettes. It appears that shimano has in fact tightend up the fit for the larger cogs for obvious reasons.

    fisty, there is no need of a mallet when installing a cassette, the cassette slides in with very little pressure. And it makes little sense that the cassette takes pressure to get to one third of the way in and then slips in ...

    Is everything nice and clean? Do you have grooves on the hub driver? Have you always put in the cassette correctly or forced it in when in the incorrect orientation?

    I had this problem with the M8000 11-42 cassette and a DT Swiss 350 hub... the largest cog was very tight but the rest were fine. The tightness was most pronounced on the spoke end of the splines when the cassette was almost all the way on, I was barely able to install it.
