## What does PCD mean on chain rings

BCD – Bolt Circle Diameter (Bike specific) PCD – **Pitch Circle Diameter** (Universal standard)

## What is Shimano PCD

It is **the Pitch Circle Diameter**. That is the diameter of a circle through the bolt holes centres. If the ring is non Shimano or Campag it will often be stamped on the ring. The easiest way to measure is to measure from the crank centre (BB) to the bolt hole centre and double it. maddog 2 Posts: 8,114.Mar 31, 2008

## How do I find my PCD

**Wheel PCD Measurement Calculation Formula**

- 4 Stud PCD = Stud distance divided by 0.7071 to get PCD.
- 5 Stud PCD = Stud distance divided by 0.5878 to get PCD.
- 6 Stud PCD = Stud distance divided by 0.5 to get PCD.

Binary Coded DecimalB. D. (**Binary Coded Decimal**) The storage of numbers in which each decimal digit is converted into a binary number and stored in a single 8-bit byte. For example, a 12-digit decimal number would be represented as 12 bytes.

## What is BCD and PCD

The diameter of this circle is known as the bolt circle diameter (BCD) or **pitch circle diameter (PCD)**. Typically BCD is quoted for bash guards covering the chainrings on bikes and you can calculate it by measuring the distance between the fixing holes of the chainring.Jan 28, 2022

## How do you calculate the PCD of a gear

Pitch Circle Diameter (PCD) – Gear Terminology

The center distance of two meshing gears is expressed as the sum of the pitch circle radii of the two gears. Since the module of the meshing gears are the same, center distance **a = (d1 + d2) / 2 = (z1m + z2m) / 2**.
