exactly.

As far as I know, Saint is only available in RR configuration, and there is a RR option on both XT and XTR.

edit: and expatriate, of my two main bikes, one has RR and one has the old fashioned style. No big deal - If I do forget, I usually get it sorted out within a few hundred feet from my house. When the old fashioned one dies, it will be replaced with RR.
