Bolt Circle Diameter is the diameter of the circle formed by the centers of the chainring fixing bolts. With 4-bolt cranksets, this is easy to measure. 5-bolt cranks are more difficult.
74mm BCD rings are the usual inner rings on triple cranksets.
If you are unsure about what size chainring you need, Wolf Tooth Components has an excellent guide to measuring your rings.
