Hi,

Can I use a Shimano WH-M975 rear wheel on my Bianchi SASS ?

Is the hub strong enough, I think it's made from aluminium.

Regards

I don't think there is need for concern. The Surly cog is steel while the freehub body is aluminum so there is a chance that they could seize like an aluminum seatpost in a steel frame but if amble goo is used there should be no reason to worry about that. The cog may make an indentation where it engages the hub, but so would a cassette. You may try to use a larger cog in the rear if you are really worried about it, something like 18-20 instead of a 15 or 16 tooth. Free hubs are replaceable easily enough too. I wouldn't worry about it, besides you're gonna get it dirty aren't you?

My concern is about the torque force on only 4.35mm (surly cog) on the aluminium freehub body ?
the surly cog is wide and will not dig into the freehub body like a cassette will, nor will you have an issue with seizing due to a metallurgical reaction. apply just a dab of grease just the same to prevent squeaking though.
