Sick-bike freewheel BCD is 67.6mm
Some basic geometry is needed to find the center of a 5-bolt pattern: But basically, the PCD can be found by multiplying the center distance between any two adjacent holes by 1.701. Generally, the PCD can be calculated for any wheel from the number of bolts (n) and the measured center distance between two adjacent bolts (d) as; PCD = d / SIN(180Â°/n).

"The hub radius is 1.06 inches or a 2.12 diameter. The hole spacing is about
1.33 radius or 2.66 diameter in a 5 bolt pattern."
= 67.733333mm BCD
however, the word "about" doesn't exactly inspire confidence in the accuracy.
