Shimano Hyperglide Cassette 7 sp

[foz]

Yes, just unscrew the smallest sprocket and the rest slide off. You'll need two chain whips.

All the UG sprockets I've seen have been loose, with no holes to bolt them together. It's not really necessary though.

I might have some spare sprockets, but I don't think so. Will have a look just in case. If you have the smallest (screw on) one then the easiest thing to do is just file one of the tabs on a standard HG sprocket and use those. Or find an HG compatible freehub body and swap it, then you can use any HG cassette with lockring and forget about the UG stuff

Regina America cogs are still available. Not easy to come by though.
