Okay, trying to figure out what works.
For my 10 speed bike, I am using a 11/32 10 speed, with a 9 speed mountain bike derailleur.
But trying to understand what parts are needed for an 11/32 11 speed shimano cassette.
If I look at the specs of their Di2 or mechanical derailleur’s, all the ones I can find say max sprocket is 12/32.
Well, they do not even make a 12/32
So, is anyone running a new 11 speed 11/32 with shimano stuff? If so, which ones? If so, any issues?
Thanks

Yep, I’ve successfully setup Shimano RD-6800-GS and RD-6870-GS (Di2) 11-speed mid-cage derailleurs with 11/32 cassettes.

Cool. Any idea what the spec says 12/32 max then?

I’ve always used the Shimano Ultegra CS-6800 11-32 cassette and a 50/34 compact crank. No issues.
Perhaps chain slack becomes problematic with a 53/39 or 52/36 crank?
I have a Ultraga mid cage with my compact and 11/32 that I put on for IM Lake Tahoe and the shop says they’re going to put it on my new road bike with Di2.
Here’s an example on my stand right now. A 48cm P2 with 11/32+50/34:
Okay, this is looking better. This below is a post that Dave made in another thread.
Don’t overcomplicate it. Just run 10 of the 11 cogs on your Zipp wheels leaving all other components the same.
I’ve set up a few bikes with 11-25 or 11-28t 11 speed cassettes by just installing the first 9 cogs then adding a 12t last position cog + lockring to give you 12-25 or 12-28 10 speed cassettes that otherwise fuction with 11speed. Limit screws prevent the derailleur from overshifting.
So, I have looked around trying to see how the CS-6800 is made. Dave said he could do this with the 11-25 and 11-28. Not sure what adding a 12t means since both come with a 12 cog.
I assume the 11-32 also has the last few cogs not riveted together so one could take the 11 out still get the lockring on?
