I figured Brian knew what the sizes are and went with that. Besides, I'm really interested in the new S/C pulley being developed and was wondering myself if we could use it in conjunction with the after market crank pulleys.
I enjoy doing math (yeah, I'm weird like that) and had some free time, and no one else checked Brian's numbers, so I did.
