I have 2012 deemax ultimate wheelset and run a sram 10 speed cassette.
Can i change the cassette with sram (not xd) 11 speed or shimano 11 speed?
Are the deemax (year 2012) compatible with 11 speed cassettes?

I don’t want to fit a sram xd driver cassette.
I want to fit a normal non xd cassette (sram nx or shimano).

Will I have a compatibility problem?

11 speed shimano-splined MTB cassettes are the same width as 10 speed so fully compatible with your wheel.

Sorry misreading all other freehub are equal but nx is heavy so it xt so just get the xd and gx
