I am really sorry to have to be this stupid, and I tried to find out on google, but;
I need to know if this is a splined style hub/casette or a screw on.
Its a Old MTB aerospoke rear wheel… so, kinda need help, and if you can identify, if you can make suggestion if it can take a 9 speed shimano cassette (as it currently has a 8 speed)
I checked out here > ( http://biketouringnews.com/touring-bicycle/unior-cassette-lockring-tool/ )
and judging by the images it kind of looks like the standard lockring stye thing for splined… but my brain is so stuffed tonight I cant even think clearly.
