I think you maybe meant to post this in the Road bike section?
However, I have a similar issue with a Sram GXP bottom bracket
I'm guessing the chainline is not quite right, although I've not actually bothered to check it yet:oops:
afaik you can get different length Octalink bottom brackets, as it's essentially like the traditional/retro square taper ones, just with the splined "octalink/isis" connection between axle and crank.
If you have some floating around then maybe try putting a couple of spacers between the small ring and crank spider, see if that gives you a bit of room to play with, otherwise I'd be measuring the chainline and finding a bottom bracket with the axle for optimum chainline.
