Bolt circle diameter (bcd) is the diameter of the circle that goes through the center of all of the bolts on your chainring. 130mm (shimano road) 135mm (campagnolo road) 110mm (compact road) and 104mm, 94mm, and 64mm (mountain) To determine bicycle chainring bcd size you need to measure the distance between two adjacent chainring bolt hole centers then look up the corresponding chai.
How to measure Bolt Circle Diameter (BCD) - Wolf Tooth ... from cdn.shopify.com The bolt center diameter is just the circle around the crank axle axis that the center point of the chainring bolts lie on. Will you need a new chain? On a 5 arms chain rings, you have to measure the distance between two neighbor bolt holes from center to center. Direct bcd measuring (a), or by measuring adjacent bolt centre distance (b) picture 4.

A 2x crank with tooth centerlines that are located at 45mm (smaller ring) and 53mm (larger ring) would have a 49mm 2x chainline. Many chainrings have the bcd shown on them but if it isn't, you'll need to calculate it.
With this measurement (b) you can refer to the table below to identify the corresponding bcd, or use one of the following equations:
The bolt center diameter is just the circle around the crank axle axis that the center point of the chainring bolts lie on. If you can't find the same type chainring because of its rarity or you're unwilling to spend the type of money being charged for nos parts, you'll need to know the chainring compatibility with your crank. On a 4 bolt chainring you can simply measure the distance between the centres of opposite bolts. If it is not labeled on your chainring, you will need to measure it. Will you need a new chain? As to the original chainring size, apparently it's not 130bcd. If you need to order a part for a bicycle, or check the bcd of a flange and can only measure the bolt hole spacing, you need to know the formula for working it out. Distance (x) bcd distance (x) bcd 41.0mm 58mm 34.3mm 58mm 45.3mm 64mm 43.5mm 74mm 48.1mm 68mm 55.4mm 94mm 73.6mm 104mm 64.7mm 110mm 72.1mm 102mm 71.5mm 122mm 79.2mm 112mm 76.4mm 130mm 103.2mm 146mm 79.5mm 135mm 84.6mm 144mm 4 hole chainrings 5 hole chainrings to determine the bcd of your chainrings, measure the distance between You can make some sort makeshift calipers if the crank arm gets in the way. In many cases the bcd is printed right on the chainring like in the example below. Direct bcd measuring (a), or by measuring adjacent bolt centre distance (b) picture 4. For dimensions of specific models, see my bicycle crank/chainring bolt circle diameter crib sheet. Bcd is an acronym for bolt circle diameter.
For the xx1 spider, we recommend the 6mm bolts (or any. The image below shows this measurement on a 104mm bcd chainring. The bolt center diameter is just the circle around the crank axle axis that the center point of the chainring bolts lie on. A 2x crank with tooth centerlines that are located at 45mm (smaller ring) and 53mm (larger ring) would have a 49mm 2x chainline. A quick way to find out is to measure the distance between the center of two adjacent bolt holes then refer to the chart below to see what bolt pattern you have.
How to measure Bolt Circle Diameter (BCD) - Wolf Tooth ... from cdn.shopify.com 5 bolt chainrings 4 bolt chainrings On bicycle chainrings this dimension is usually measured in millimeters. Classic methos how to measure bcd is : Pick two bolts where a line between them goes through the axle axis. It is easier to measure the distance between adjoining chainring bolts as depicted by a in the above picture. It gets slightly more difficult if you have multiple front chainrings. The below pictures show the taking of these measurements with a tape. The image below shows this measurement on a 104mm bcd chainring.
If you need to order a part for a bicycle, or check the bcd of a flange and can only measure the bolt hole spacing, you need to know the formula for working it out.
On a chainring with 4 bolts, the bcd is the distance between two bolts across from each other. When measuring from the bolt, make sure you begin and end at center of the bolt hole. This page gives an overview of how to measure bcd. Measuring distance between adjacent bolts to calculate the bolt circle diameter. For the xx1 spider, we recommend the 6mm bolts (or any.
