Even Sutherland's is a little confused. The 3rd Edition says 120mm, the 5th Edition says 119mm, then the 6th Edition says 120mm again. Some old SR brand cranks were 118mm. I once tried drilling out the bolt holes on an SR chainring and filing out the inside of the ring to make it fit a Zeus crankarm. I was actually able to mount the ring, but there was so little metal left between the bolt hole and crankarm, I was afraid to ride it.

I am looking for rings to fit a zeus crank which I believe may measure either 120 or 119 mm bcd (I am told that Sutherland's calls them 120, but folks have measured them as 119) In any event, I need them to fit a zeus crank...thanks sorry for the confused-ness
