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.

Many makers have produced cranks and rings using a 110mm BCD, including Campagnolo for its compact cranksets, Sugino, SR FSA, Surly, White Industries & Shimano.

If you are unsure about what size chainring you need, Wolf Tooth Components has an excellent guide to measuring your rings.
