Says in the description it's NOT I-spec so guessing its bar mount, took a punt myself anyway.
Postage to pay but still half the price

Save your money and buy an xt shifter with bearings instead of bushings. A low end deralier can feel good with an xt shifter but a high end deralier will still feel rubbish with a low end shifter.
Xt shifter minimum with slx mech or above wins for me.

Those ones from flat out cycles are second hand though, regardless of them being off a new bike, they have still been fitted and as such are used!
