Thanks!
A few pages back I changed out the stock stuff for a GXP Force1 crank set. After a brief search I can't seem to find a proper dimension for you for the direct mount on the interwebs. I will say, the stock 42T ring bolts right up to the Force1 crank. I am using the Force1 40T however. I measured the stock crank arms I have on the shelf, the OD of the DM spline is 40mm, and a rough dimension of bolt spacing is 38mm.
