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.

144mm is the bolt circle diameter of an entire generation of 1960s, 70s, 80s and even 1990s cranksets, including Campagnolo, Sugino, Mavic, Stronglight, Ofmega, SR, SunTour, Gipiemme, Zeus as well as others.

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