What spacer(s) do i need?

[vqdriver]

Have 11sp shim dt freehub, but lack whatever spacer.
Want to use a 10sp cassette. Shimano product description says for 10sp i need a 1.85mm and an additional 1mm. But recall seeing a single spacer being referred to. So i need 1 or 2 diff?

If you have a 105 or above Shimano cassette, you need both. All other 10s cassettes, you only need the 1.85.

There is a 2.85mm spacer available that does the job of both. Either-or.

My DT Swiss wheels with an 11-speed Shimano FH just arrived with only a 1.8mm spacer.
