Both Shimano but the cassette is 11 speed and the derealleiur is 10. Can the shifter or something else be adjusted so it works with smooth shifting or does cassette need to be changed ?
No, for shimano, it will not (even if you have an 11 speed shifter).
The cable pull ratio for shimano rear derailleurs changed for 11 speed, when shimano changed from 10 to 11.
Are all your components, except the cassette and including the chain and rear wheel hub, 10 speed? If the answer is yes, I don’t think so. For example, 10 speed chain is thicker than 11 speed, so I don’t think it will shift properly from 11 speed cog to cog. 10 speed wheel hub without modification cannot be used with 11 speed cassette.
Yes everything on the bike is 10 but the wheel has a 11 speed cassette
.
So is it the wheel or is it 11 speed that you’re after? The easiest fix, if you’re after the wheel, is to use a 2.8mm spacer with a 10 speed cassette. There should be a 1mm spacer already underneath the cassette. You can also just add a 1.8mm spacer to that. That’s assuming that you’ve got an 11 speed hub (and not a 10 speed hub that was modified for 11 speed).

Okay let me give a bit of more detail as I probably wasn’t clear.
I’m selling my wheels that has 11 speed free hub and 11 speed casette. The (potential) buyer has a 10 speed set-up ie shifter derailleur etc is all 10 speed and so is his current wheel

In short, no, that will not work. The person you are selling the wheel to needs a 10speed cassette and the 1.8mm spacer - and possibly the 1mm spacer if using a shimano 10sp cassette.
He can use the wheel with a total of 2.8mm spacer and a 10 speed cassette. As far as I know, he cannot use the 11 speed cassette.
No, for shimano, it will not (even if you have an 11 speed shifter).

Please correct my misconception for me…
The R. Der is basically a spring that gets pulled by the cable. The shifter determines how much cable is pulled for each shift. If he had an 11sp shifter and 11sp cassette, thats where the cable pull indexing comes from. The R. Der is moving whatever distance the shifter pulls the cable. I see the 10sp R.Der not being able to pull through all 11 cassette gears because of overall swing capacity of the derailleur, not the cable pull built into the derailleur itself?
I can see why a 10sp shifter and 10sp R. Der wouldn’t work with an 11sp cassette, But 11sp shifter, 11sp cassette with a 10sp R.Der?
Again please correct my misconception on this setup. Thanks
If you run SRAM this will work. For my current setup: 11s shifter, 11s chain, 11s cassette, 10s FD, 10s RD, works like a charm. Cable pull/indexing with Shimano systems is a bit more nuanced (I don’t know the details) and afaik will not work in this configuration.
Just remove the 11 speed cassette and put on a 10 speed cassette and your friend can use the wheel. Don’t overthink it.
No, for shimano, it will not (even if you have an 11 speed shifter).

Great question.
You are generally correct, but there is a missing piece of info.
Say you have a 10s shimano RD and a 10s shimano shifter (indexed).
Then, say you have a 10s sram RD and a 10s sram shifter (indexed).
Even though all of the parts are 10s, the cog spacing is identical, and the indexing is all in the shifters (as you correctly surmised), you cannot switch them and use a shimano 10s shifter with a sram 10s RD (and vice versa).
RDs are “dumb” but they still have an exact design geometry, they each require a certain amount of cable pull to move a measured amount. And that amount of needed cable pull often changes from brand to brand and from generation to generation (10s to 11s, etc.).
On a side note, the cable pull of shifters (and RDs) is not linear. For example, for a given system, the amount of cable movement needed to shift from the smallest cog to the next largest cog is measurably different from the amount of cable movement needed to shift from one the bigger cogs to the biggest cog. And indexed shifters reflect this, they do not pull the same amount of cable with every click. It varies, depending on which cog you’re shifting across.
Awesome,
I was kind of assuming that it had something to do with geometry of the of the R.Der and the geometric difference between speed types but was unsure. Also didn’t realize that the cable pull wasn’t linear with each click…
Thanks!!
Glad to help.
All that said, some shimano RDs had the same cable pull ratios across some generations, where you actually could use some particular 8s RDs with 9s shifters and some 9s RDs with 10s shifters. But not all of them. Not sure about sram.

Gee, if only there were a way to have non-discrete shifting built into the shifter, so one could explicitly control the amount of cable travel. Maybe use, I don’t know, “friction” to keep the shift lever from sliding out of position. Nah, never work.

No worries, I did my first decade plus of riding and racing on friction systems (campy record downtube shifters to be precise), so I do have a little bit of an idea of what you’re aiming at.
But, having now used both systems for a long time, I gotta say, indexing is an impressive improvement. I’m not highly motivated to go back.
But I wasn’t offering an opinion for or against here, just trying to help the OP …
Have 1x SRAM. 11sp med cage RD, 10sp shifter and cassette
