Can I fit a Truvativ Noir crank to my Stumpy?

skeetam

Hi, my Stumpy 2010 Expert Carbon came with a Shimano Deore crank and I'm looking to change it to something lighter. I bought a Truvativ Noir crank with a GXP BB second hand but when I came to fit it I found that my stumpy has a press-fit bottom bracket and not a threaded one. Does anyone have any advice about how I can fit these?

Any help would be much appreciated.

This looks like the BB I currently have on my Stumpy.
