Mavic 11 speed freehub body length

[Veloo]

I have a set of Speedcity wheels from 2011. I'm running single speed on it right now but wanna go to 11. I don't have an 11 cassette to test it out.
Does anyone know what the length of the 11 speed compatible Mavic freehub is?

Most, if not all, mavic wheels are 11 speed compatible by default.

As long as you have to use a spacer on the back of the cassette with 8/9/10 speeds an 11 will go right on without it
