Okay that's an indexed shifter.No idea. Bog std Shimano Gripshift things.
Old chain wraped around the cassette then wrap some old cloth around it and you have a chainwhip but you should really go and get a lockring removal tool, they fit shimano and sachs so it will likely be used again.As you say, a simple swap of my existing cogs to the new hub. And all that's needed to do this is a chain whip? I'm not a big fan of buying tools I'll likely never (or seldom) need again. Can the swap be accomplished with a section of old chain? My existing chain is probably on its last legs so would make sense to renew that at the same time. I know I'd need a chain breaker.
so it's really a case of built-in obsolescence?7 Speed cassettes are mostly obsolete but there are still some around as new old stock.

If you get an 8-speed cassette you will need a new shifter and a new chain as well since the spacing between the cogs is different for 7 vs 8. It's not just a matter of not being able to use one of the 8 gears. The indexing will be off so it will run roughly and noisily.
And lo.....it was 130mm size hubuch:At my level, seems pretty pointless. Ended up with an AT4500 32h laced 4x. Seller says the hub accepts 8/9/10 speed sets.
Should be okay for my careless riding, I suppose.
