all i know is:
i have the road kind on my fixie (used to have a double on them), they have a 144bcd, they fit just fine on a shimano bottom bracket (the one that came in my frame), seem really nice and stiff, and i get a nice chainline with the ring in the outside position but the BB does seem unusually narrow compared to my other drivetrains.
if you have a few different width BB's to play with i am sure you will be able to make these cranks work real well!
