I have a new bike with Shimano, 105 di2 and 7100 34t cassette. I took it off for a clean yesterday, and a small, very thin spacer fell onto the ground, that I assumed went behind the main cassette body on the free hub. When I reassembled it, it was very apparent the spacing around 9 to 10 cassette sprocket mark was wrong. Turns out that the regular black spacers that go between the sprockets have been kept for several of the spaces but between nine and ten a much thinner space is needed. Just a bit of information in case anyone finds the same problem that I had. Screenshot of the relevant Shimano document below. I also believe that this cassette is only working on Di2 which seems a bit odd, but not going to cause me a problem
