Thats not the reading I’ve been doing.
The issue is the 11 speed hub is 1.85mm longer than the 10. On the R7000 cassette there should be a 1.85mm recess at the back of the largest sprocket. To fit r7000 on an 11 speed hub you should always need a spacer… at least from my reading. I’ll be putting it to the test myself soon enough.
