• Aaaah of course it's a uniglide freehub body, I didn't take that part in fully, you're new freehub body will be a hyperglide one but don't let that worry you you will just need a new lockring for it which you can use your new tool to tighten. With a bit of luck if the bike shop you gointo to buy a new freehub has just serviced a bike and replaced a cassette that day they may have an old lockring in the bin to give you.

    More info Sheldon Brown has a page on shimano freehuhbs, google.
