Its a 5 arm Race Face North Shore crankset, with a 38T chainring if that helps. The crank is probably a couple to a few years past.
BCRider said:Google for Harris Cyclery. Somewhere in their site they have a table that gives the BCD and the measurements between each bolt center. With that bolt to bolt center distance you can see what your BCD is.
It's a very handy table to have. I should have copied it for myself a long time ago.
