asked by: a guest Will this fit on a Shimano Alfine 8 spd. hub?
anwered by: moharris No. This 9-spline cog will not fit an Alfine hub, as AlfineNexus hubs are only 3-spline. To fit an Alfine hub you would need a cog similar to this product: Carbon Drive CDX CenterTrack Rear Sprocket 24 tooth Nexus/Alfine http://www.treefortbikes.com/product/333222384956/716/Shimano-Alfine-S501-8-Speed.html#navbar=pro___333222394390___804
