## How do I know my bike chain size?

Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm). The result is the ideal chain length for your bike. For example, you’d add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.

## What size is regular bicycle chain?

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.

## How do you measure chain size?

To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.

## What do the numbers on a bike chain mean?

Bicycle Chains are generally categorized into two types: 1/2 × 1/8 and 1/2 × 3/32. The first number (1/2) is the chain pitch; the latter numbers (1/8 and 3/32, respectively) indicate the inner width in inches. Number 1/2 × 3/32 chain is used with a derailleur.

## Are all bicycle chains the same size?

Are all bicycle chains the same size? No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.

## What size bike chain do I need single speed?

1/8″ chains are used exclusively for single speed setups. In addition to the other answers, I found it helpful to read that the nominal width of a chain (1/8 or 3/32) actually refers to the width of the sprocket.

## 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

## Is my bike chain too short?

If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog. Before you remove the chain, make sure it’s on the small chainring and smallest cog.

## How strong is a bicycle chain?

Wippermann’s internal standard is 9,500-11,000 Newtons of breaking force for its bicycle chains, and they achieved that; some of the others fell short of that.

## What is the difference between.325 and 3/8 chain?

The three-eighths chain is a beefier saw and better suited to one that has more horsepower. It has larger teeth and a heavier duty chain, so it requires more horsepower to operate correctly. 325-inch chain for those saws between 40 and 60 cc.

## How do I set the size of a chain link?

Chain Link Sizes: How to Measure Chain Link Sizes

- Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
- Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you’re seeing a good average size.

## What is the difference between 420 and 428 chain?

The primary difference between 420 and 428 is the pitch of the links. A 130 link 428 chain will be longer (and generally speaking, heavier-duty) than a 130 link 420 chain.

## What is the difference between a 520 and a 530 chain?

The difference is width. 530 sprockets are 3/8″ wide, 520 are 1/4″ wide. 530 chains and sprockets are stronger because they’re thicker, but they’re also heavier.

## How do I know what speed my bike is?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.
