I assumed it was an 11 speed as the Spline length is 35mm (10s is normally 33mm) I double checked Google which kept coming up 8/9/10, I offered up an 11 and it fitted (shown in the photos) so confident it's an 11. I'm guessing it will be used to salvage the FHB, incase you need the complete unit the bearings are good, it came from a damaged rim so perfectly usable. Full working order, no issues. 20 hole (straight pull). Standard 130mm O.L.D.
