# FAQ: What Pitch Is A Standard Bicycle Chain?

## What is a normal bicycle chain size?

Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.

## What is the difference between 1 8 and 3/32 chain?

Bicycle chain comes in two basic widths: 1/8″ chain is used on most single-speed bicycles, and bicycles with internal gearing. 3/32″ chain is used on derailer equipped bicycles that have more than 3 speeds.

## How do I know my bike chain size?

Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.

## What is the pitch of 40 chain?

We know that from the ANSI numbering system, ANSI 40 chain has a pitch of 4/8s of an inch or. 5 inches.

## Are all bicycle chains the same pitch?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

## How often should I change my bike chain?

The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4

## What does a 3/32 chain mean?

3/32″ chain is used on derailer equipped bicycles that have more than 3 speeds.

## Are 6 7 8 speed chains the same?

5, 6, 7 and 8 speed chains Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm.

## How can I tell if my bike chain is stretched?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

## Which is bigger 35 or 40 chain?

The main difference between the 35 and the 40 chain is that one is rollerless and the other has rollers. The two chains also have different pitches and diameters, which will limit their interoperability. Additionally, the 40 chain is rated for a significantly higher tensile strength and working load than the 35.

## What is chain pitch?

In terms of conveyor chain, pitch is usually defined as the distance between links, as measured from the center of the roller pin on one link to the center of the roller pin on the next link. Note that some precision link conveyors refer to the pitch as the link size.
