Compatibility, Size and Fit
This cassette is named for standard HG hubs and for 9-speed use. It also states fitment for 9/10/11 speed HG MTB freehub bodies, while noting no XD or micro spline compatibility. Check the rear hub standard before purchase, since that is the main fit point for this part.
Before You Decide
Confirm the hub standard, drivetrain speed, and the 12-46T range before choosing an offer. If your bike uses XD or micro spline, this cassette is not the right match. It is also worth checking that your selected drivetrain parts align with the Prime 9 naming.
