hey guys...

i have got a new frame that is apparently a very limited addition, it is a relaunched GT pulse track frame, im in the process of building it up... and the biggest problem im having and have heard of is finding cranks that will fit to this frame (especially the 'large' size frame, which i have) the first crank i thought of is truvativ omnium crankset...the problem is that the crank SPIDER hits the chain stay and i cant seem to find any crankset that will fit this frame....it is a BB86.
i heard that FSA has brought out a bb386, but is that only specific to FSA cranks? or does anyone out there know of a crank that will fit my frame?!

any help is much appreciated!!
