12-32 cassettes becoming obsolete?

Are 12-32 cassettes becoming obsolete. Everywhere they seem to be out of stock or overpriced compared to 11-32.

For some reason I'm unable to edit the title, should be cassettes not freewheels.

You could buy the 11-32T, throw away the 11T, and buy a 12T cog and 12T locknut.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

Yes 12xanything cassettes are getting hard to find. My favorite 12x27 10-speed is out of production and nearly impossible to find and 12x30 10-speed is getting hard to find. I don't understand this fixation with 11T cogs unless you are using a 46T big chainring or smaller.

How many speeds? The Shimano and SRAM 7-speed ones are still pretty easy to find.

I’ve a 12-32 eleven speed on my gravel bike. I combined the cogs from an 11-32 and a 12-25. I used the remaining cogs on my trainer.

8 speed CS-HG200-8 with 12-14-16-18-21-24-28-32T spacing to use with 42/45t half-step gearing for durability and size restriction on smallest chainring.

Can't use 11-32T due to incompatible spacing with the 42/45T half-step gearing.

I don't get it either, nor do I like this trend.

Probably the only way is to get any two cassettes containing 14, 16, 18, 21, 24, 28, 34 cogs including appropriate spacers and then combine as one needs.

Turns out 8 speed drivetrans were starting to become obsolete since 2007.

You found a thread from 2007, but Shimano had already released 9-speed in 1996: https://en.wikipedia.org/wiki/Shimano#Road_groupsets

The 11-32 would actually half-step beautifully with 45/42, for what that's worth...

Looks like 11-32 would half-step only with the 18,21,24,28,32 and not 11, 13, 15.

​​​​​Apparently it took quite a long time for the market since 1997 for 9 speeds to reach the bottom of the barrel social backwater then.

No, the whole thing half-steps. Not perfectly, but it was never perfect BITD either. Isn't this going on an e-bike anyway?

​​​​​​
Actually 11-32 cassette should be better since there isn't unnoticeable 7%/5% gap between 18T and 16T sprockets.There is 7%/12% instead which is almost too noteceable but better.
I might even remove the 11T sprocket and use it as a spacer between the hub to improve the chainline if this is technically possible.

11:32 gives a 2.91 gearing range
To get the same with 12T, one needs a
12:35

And, a bigger cassette, derailleur, chain, etc.

You can adjust your top end gearing by using a smaller chainring.

Seems as if one gear would be enough for an ebike.

Then you will have to mix your own cogs. All of my cassettes of 9 and 10 speeds are mixed from 2 or 3 different groups. It is probably easier to mix a 10 or 11 speed cassette, since there are more variations available. Or you can get a custom Miche 10 or 11 speed cassette, but 10 only goes up to 30T and 11 goes up to 34T. I assume you could try taking the 34T from 11 speed, and put it on a 10 speed mix, but you have to work out the correct spacing due to the different offset on the last position cog.

If I'm understanding you correctly, it likely wouldn't be possible (at least not without significant modification). Most of the lockring sprockets, like the 11T in this case, have "end caps" to their splines, which means they won't slide all the way on to the freehub. You can slide them on a few millimeters and then they'll stop at the spline "end cap". You sometimes have to shim a cassette if it's loose even after tightening -- because the lockring sprocket will continue to compress the cassette cluster only until it bottoms out on its "end caps".

You said you wanted to use the 11T sprocket as a "spacer between the hub". I understand from that that you want to place it as a the innermost sprocket on the cassette (which would not work). The other thread talks simply of omitting the smallest sprocket if the cassette "hangs off" the freehub body or you don't otherwise want it, which certainly is possible.

Back to my reply, I must not be understanding correctly your intent of a "spacer between the hub".

I have a 11 speed freehub with a 1.75mm spacer for 10 speed cassettes, now I might need another spacer intended for 7 speed cassettes.

Miche seems to offer a lot of variations on their cassettes. You should be able to get what you want from them.
