I have Scott Spark 930 2020 with Shimano 12 speed hub (not Microspline)
Now I might have done a weird thing - decided to buy a new rear wheel:
DT-Swiss M 1900 Spline DB 29 Sram XD, 148/12mm Boost TA, and bought a new cassette for it - XG-1275.

After assembling everything together I found out that my new cassette is wider than the old one, and the smallest cog is too close to the derailleur hanger, so the chain jams:

I'm not sure what to do... I tried to put my old hub driver onto the new wheel, but it seems that it's incompatible.
What would be the easiest way to make use of my new wheel?

Is the xd driver installed correctly and seated into the hub shell?

Is your cassette tightened on completely?

Shimano don't make a 12 speed hub that isn't Micro Spline do they?
HG= 8,9,10,11 speed and 12 speed NX
MS=12 speed Shimano
XD=11, 12 speed SRAM?

I'm guessing the cassette isn't all the way on. Did you use a torque wrench set at 40nm?

It seems, indeed the tightening of cassette was not enough. I don't have a 40nm torque wrench unfortunately, so have to trust my hands feeling . But after tightening it, it became better. Thank you!

I’d get a decent torque wrench for the few things that really benefit from correct torque. XD cassettes are one for sure. It’s hard for me to tell with accuracy how tight to go on those. Crank arm bolts, and a few other high torque things.
