Hyperglide cassette limitations
I have my eye on a wheelset with a Shimano hyperglide connection.The cassette is 7 speed.Does it take a special chain?Will it work with any Shimano derailleur?Thanks.

A wheelset with a 7-speed Hyperglide cassette is likely to be 15 to 20 years old. Are you sure this is what you want?
It will accept most chains, but a 6/7/8-speed would be preferred. I prefer SRAM chains, but there's many available: https://www.niagaracycle.com/index.ph...sort=2a&page=2
Shimano derailleurs are generally cross-compatible. There are certain limitations regarding chain width (7/8 vs. 9 vs 10-speed), capacity (road vs. mountain) and cable pull (the majority vs. Dyna-Sys vs. old Dura-Ace). More information is needed.

As Jeff said, there aren't serious chain issues to consider, but you need to check other details. I assume you currently have a 7s bike or at least 7s shift levers. If not you need to match the number of speeds on the cassette to the shift levers. Also check the axle width. Many 7s wheels have 126mm axles, whereas your bike may be 130 or 135mm. There's some fudge room achievable with springing the frame in or out to match the wheel, but why create a problem with a new purchase when the exact wheel you need is available?

because you can run whatever 8-, 9-, or 10-speed cassette you want on the 7speed freehub body. You'd just need to ditch one cog and add some spacers. All other things being equal, it'll be a stronger rear wheel that way. And, I imagine, a pretty cheap one.
This bro may also have a 126mm spaced frame...

I like 7-speed, myself. Only problem with older stuff is that you need to be more self-reliant when it comes to sourcing replacement parts...

Indexing adjustments on 7spd bikes are far more robust, and if your frame is 130 or 135mm, can make for a very strong rear wheel if you fit a longer spindle and re-dish the wheel.
But if you have 8spd shifters, I don't think it's worth it. Better to find an 8spd wheelset, or if the 7spd one is cheap enough, fit an 8spd cassette body and re-dish.
Of course, the above is affected by your weight, budget and mechanical aptitude/knowledge. Brush up on that last by studying Sheldon and Park.
