Hi all, I'm trying to identify the rear hub I have on my MTB.

It's a 2010 boardman comp fi women's and has the original ritchey pro disc wheels on.
The hub has some play in and I need to replace the hub body as well as having it serviced(as advised from my LBS)
There is no identification on the hub at all.

I would like to do this myself if it's possible and not too difficult, but I want a like for like on the parts (or better if I could)
There are lots of options as well as huge differences in price, so I don't want to buy the wrong thing.

If it helps, it's a 9 speed cassette fitted. The shifting is sram x7
