Shim.9 vs Shim.11 cassette body

I think that Shim.9 cassette body from your e-shop is suitable for my Shim MTB 11 speed cassette. Can you confirm this?

Yes, you are totally right about that. Naming for Novatec cassette bodies should be understood like this:

- Shim.9 cassette body: is meant for Shimano 8/9/10 speed ROAD cassette and for Shimano 8/9/10/11 speed MTB cassette    

- Shim.11 cassette body: is meant for Shimano 8/9/10/11 speed ROAD cassette and for Shimano 8/9/10/11 speed MTB cassette thanks to 1.8mm spacer that comes with it.

Important: This spacer is to be used for Shimano 8/9/10 speed ROAD cassette and for Shimano 8/9/10/11 speed MTB cassette.
In other words, by using this spacer you turn your Shim.11 into Shim.9 type of cassette body.
Remove the spacer only when fitting Shimano 11 speed ROAD cassette.
