Since the bcd probably isn't stamped on your crankarm, you need to take a measurement and do a calculation.
If it is not labeled on your chainring you will need to measure it. You could measure the distance from the bb spindle to the center of one bolt hole (gives you the colt circle radius) and double it. On a chainring with 4 bolts the bcd is the distance between two bolts across from each other.
When ordering a chainring make sure you get one which has the same bolt spacing pattern, although from this page i'd say you have evenly spaced bolts.
For the stout crankset we recommend the 10mm bolts or the bolts that come with the crankset. You could measure the distance from the bb spindle to the center of one bolt hole (gives you the colt circle radius) and double it. This is usually easier to measure directly than the actual bolt circle diameter. On a 4 bolt chainring you can simply measure the distance between the centres of opposite bolts.
