Correct BB?

I need to replace the bottom bracket on my 2013 Scott Genius 720. The spec says it's a "BB-92 Press Fit", and the chain ring is a Shimano XT M785.

Looking on Chain reaction, there doesn't seem to be any mention of BB92 - however they do this one - http://www.chainreactioncycles.com/au/e ... -prod44225 - which has a diameter of 92mm.

Is this the one I need?

Thanks for any help.

Yes.

Thanks

Any idea why it's referenced as BB91 when it seems to be either 89.5mm (with spacer) or 92mm (without)? And is there an easy way to understand the different 'standards' that are out there?
