Web23 jul. 2009 · 1-Newbie. (To:ptc-2708796) Jul 23, 2009 04:03 PM. In the past I have done it two ways: 1.Sketch a circle on the drawing over the bolt holes and dimension it-this only works if the scale of the part is 1.000. 2.Sketch a circle over the bolt holes, then add a note to the circle-the note is so you can type the dimension when the scale is not 1.000. WebIf it is not labeled on your chainring, you will need to measure it. On a chainring with 4 bolts, the BCD is the distance between two bolts across from each other. It can be somewhat difficult to make this measurement if you don't have a caliper because the crankarm gets in the way. The image below shows this measurement on a 104mm BCD chainring.
