Will have to add spacers? Is this going to cause any issues with shifting/alignment? 11 or 12 speed offers many more options it seems so my life might be easier if I can go that route. In looking at all the different parts I'm obviously concerned about compatibility, was hoping there'd be a good set I could find that would work.
Thanks so much for the suggestion!
To be clear: there is no difference between a freehub body made for 8/9/10 speed and 11/12 mtb for HG driver freehubs like yours. 11/12 speed road is different. A new Sram NX 11/12 cassette, a microshift cassette, a 1x11 Shimano cassette, will all work on your hub perfectly with no hacks or modifications. The only cassettes you can't run are those that use a xd or microspline driver.
