Answer: 
In a four hole system such as SRAM the BCD (bolt circle diameter) is simply the distance between the hole centres of two opposite holes and is best measured from the outer edge of one hole to the inner edge of the opposite hole.

Five hole systems such as Shimano are more complicated.

1. Measure the distance between adjacent holes. Call this distance C.

2. Then the BCD is given by: BCD = C/sin(180/N) where N is the number of holes.

Answer: 
The bolt circle (BCD) refers to the distance between the bolt holes on the chainring. This is important as chainrings and cranks can have different bolt spacings.

The way to identify your current crank/chainring BCD is to get a ruler and measure the center to center of two adjacent bolt holes.

45.3mm measured will equal a 64mm BCD the most common for 22t size.

I need a 10 speed XT m785 26 tooth 64 bcd chainring-There does not appear to be this specific chainring available at the mo on the CRC site - but you have a M770 26 t 64 bcd inner chainring which looks the same- but is a 9 speed. Will this chainring work on a 10 speed crankset and with 10 spd chain?

Thanks

Answer: 
The tooth profile on a 9-speed chain ring is too wide for a 10-speed chain to run efficiently and is not a recommended combination.

The suggested chain rings below are both 10-speed compatible.

Answers

Answer: 
Different chainset gear ratios seen on Triple or Double standard or compact chainsets will denote the overall gearing feel of your drivetrain along with the cassette ratio that you are using. Depending on what your riding style/application is will help determine what gearing styles will be best suited for you.
A triple chainset offers you a different range of most gears when compared to a Double chainset etc.
Normal standard gearing chainsets will have chainrings that have a 130mm BCD usually and have larger tooth counts than what you will see on Compact Gearing chainsets that run smaller BCD sizes of 110mm.

You ideally want to get a gearing set up for chainset and cassette that matches how/what you ride.
