For a 24 speed does the hub have to specify 8?

If I have a 24 speed, when looking for a 36h hub it needs to specify 8 somewhere in the description? I.e. 8/10/11 - one that says 10/11 wouldn't work? Or is that shorthand?

Thanks.

If it fits 10/11, it will fit 8 or 9 as well. You will need a spacer behind the cassette, if its an actual 11 speed freehub.

What do I need to look for that won't require a spacer?

Shimano compatible 8/9/10 freehubs are all the same. Some 11 speed cassettes will fit on the 8/9/10 length freehubs, if they have a 34t or larger large cog. Freehub bodies that take an 11 speed road cassette will require a 1.8mm spacer behind your 8 speed cassette. Most 11 speed hubs come with the necessary spacer included.

Hubs with 8/9/10 freehub bodies are the most common and should not be hard to find, although 36 spokes will make them more rare. You will probably have more luck searching for Tandem bike wheels. I would be surprised if you could even find a 36 hole hub with an 11 speed freehub.

To clarify if my bike is 24 speed - i.e an 8 gear cassette the 11 speed spacer won't be an issue?

It is harder to find an 8-9-10 shimano hub now days. I built a rear wheel for a friend with an 11 sp. hub and the hub came with the spacer.

No. It won't be an issue.

a little heads up.
I fixed up an old hybrid a few years back, probably 20, 25 years old, mid to low quality parts, 7 speed.
I was thinking of changing it to 8 or 9, but soon realized that the rear wheel, while having good spacing, ie a 135mm hub, 36 spokes, does however have a shorter freehub on it, so it can only take up to 7 speed. The freehub is shorter than my 8 and 9 speed freehubs.
So just left it 7 speed as it wasnt worth either buying a diff freehub (probably 30 bucks) or finding a diff used rear wheel--given the use of the bike.

so just be aware of this if you go looking at used wheels.

an 8-speed cassette will require a spacer on any modern hub. there's nothing wrong with that spacer, no compromise in performance or aesthetics. just use it and move on.

You need to buy what fits your needs. By this I mean you need to buy a hub that will service what you ride. As noted, if you need 135mm OLD quick release hub with 36 holes, you basically need to find a 10 speed compatible freehub that fits your budget.

In all honesty, I don’t even know if Shimano makes high end 135mm 11 speed hubs with 36 holes. I assume that they might, but I haven’t looked.

IIRC, you have rim brakes. If I wanted a fairly stout non-disc hub I would look at Shimano’s trekking series. I know they are made with 36 holes. If you can find XT-780 hubs, might be tough, I’d look for those. The Deore T-610 are not bad either.

That's what I ended up ordering on ebay.
