They are in the garage not doing anything now. I have listed them on the classified. It's a 10 speed hub, but you can put a shimano 11-34T 11s cassette on (CS-HG700-11) as it has cross 10/11 speed compatibility.

you might want to double check irl but I believe mavic 10 speed hubs are 11 speed compatiable as they made the 10 speed cassette too long by accident and stuck with it

out of interest what did you do with the 10s mavic helium wheelset? and would they take 11sp?
