This has been a huge learning curve. I got some new wheels and ordered the wrong freehub body. So I figured I would just upgrade cassettes. So here’s what I tried….after lots of light research…
I put an “11speed GX XD cassette” on an “XDR freehub body with the spacer” on a bike with “Sram rival 11sd derailleur”
Everything fit perfect but the smallest cog then rubbed the dropouts bad.
Where did I get fuckered? Can I remove that spacer?
Thank you friends!
