## What size is a standard bicycle chain?

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.

## Do bicycles use 35 chain?

#35 chain is the most common type of chain used on mopeds, mini bikes, and full size go karts.

## 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 is ANSI chain number?

There are 14 sizes of roller chains regulated by ANSI. For easy reference, these are numbered 25, 35, 41, 40, 50, 60, 80, 100, 120, 140, 160, 180, 200, and 240. Some manufacturers include chain numbers 320 and 400 to the list of standardized chains. Number 41 chain is a narrow variation of number 40.

## 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 is the most common bike 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.

## Will a #40 chain fit a 35 sprocket?

No. A #40 chain is 1/2″ between the pins and 5/16″ inside width. A #35 is 3/8″ between the pins and 3/16″ inside width. There is no way it will work.

## How strong is 35 chain?

The Premier Series 35 simplex chain offers an industry-leading high tensile strength of 2,430 LBS and a 560 LBS maximum working load.

## 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.

## 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.

## 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.

## What is chain pitch?

Chain size is commonly referred to as Pitch. In actuality, chain size is determined by the chain pitch. Pitch refers to the measurement from one roller-pin center to the next roller pin center of a given chain. ANSI (American National Standard Institute) chain pitch is always measured in 1/8” increments.

## How do you read a chain number?

Chain types are identified by number; ie. a number 40 chain. The rightmost digit is 0 for chain of the standard dimensions; 1 for lightweight chain; and 5 for rollerless bushing chain. The digits to the left indicate the pitch of the chain in eighths of an inch.

## What is a silent chain?

A silent chain is essentially an assemblage of gear racks, each with two teeth, pivotally connected to form a closed chain. The links are pin-connected, flat steel plates with straight teeth. Silent chains are quieter than roller chains, can operate at higher speeds, and can transmit…
