What is the pitch of a standard bicycle chain?
one-half inch
All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches.
What number chain is a bike chain?
Number 1/2 × 1/8 chain is used for simple transmission without speed shifting; it has the same construction as Standard Roller Chain. Number 1/2 × 3/32 chain is used with a derailleur….1.5. 1 Bicycle Chain.

How do you find the pitch of a chain?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
How do you measure the pitch on a bike chain?
Bicycle driving chain pitch It is measured by measuring the distance between 3 links, then dividing it by two. Chain pitch is shown with green markers, though it is determined by measuring the distance between 3 adjacent pins (blue mark) and dividing it by two.
What is a chain pitch?
Chain pitch is the size of the chain and is defined as the distance between any three consecutive rivets divided by two. Oregon chain is made in several pitches – 1/4″ is the smallest, 3/8″ is the most popular, and 3/4” is the largest.
What is a pitch on a chain?
What is chain pitch?
What is a 1/8 bike chain?
1/8″ (0.125″, 3.18 mm) chain is used on most single-speed bicycles, and bicycles with internal gearing. 3/32″ (0.094″, 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear.
How do you calculate chain pitch?
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.
How is chain pitch measured?
How do I know what pitch my chain is?
What is the pitch of a bike chain?
The bike chain link pitch (distance between pin centers) is standardized and equals 1/2 inch or 12.7 millimeters. Historically there were also other pitch sizes, but the 0.5-inch pitch is standard these days. The total length of the bike chain is calculated by multiplying the number of links with a 1/2 inch link pitch.
What do the numbers on a bicycle 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 × 1/8 chain is used for simple transmission without speed shifting; it has the same construction as Standard Roller Chain.
How many types of bicycle chains are there?
Bicycles are categorized as shown in Table 1.7. In addition to bicycles, these chains may be used in low-speed, light-load transmission operations, for example, in agriculture machines or with electric garage door openers. Bicycle Chains are generally categorized into two types: 1/2 × 1/8 and 1/2 × 3/32.
What is a 1/2 roller chain used for?
Number 1/2 × 1/8 chain is used for simple transmission without speed shifting; it has the same construction as Standard Roller Chain. Number 1/2 × 3/32 chain is used with a derailleur.
