How do I know which bike chain to buy?

When selecting a chain, the first consideration is the number of rear sprockets. The rear cog sets have been made with 5, 6, 7, 8, 9, 10, 11, or 12 sprockets. As the number of cogs on the rear hub increases, the spacing between cogs tends to be reduced.

How do I know what size chain my bicycle needs?

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.

How do I know my chain size?

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.

What size chains do bikes use?

The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.

Are bicycle chains universal?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. … However, this does not mean all makes and models of chains are interchangeable. There are two basic types of bicycle chains: “one-speed” chains, and derailleur chains.

What size is 10B chain?

10B roller chain is a 5/8″ pitch metric size chain that is manufactured to conform to all BS / DIN / ISO dimensional standards.

What do the numbers on a bike chain mean?

Chain size is in inches, the three digit number used to describe the chain size is based on the “rule of eights”. The first digit is for chain pitch. This is the distance between the pins. The second and third digits combine for roller width, with a decimal point inserted between the second and third digits.

How many links should a bike chain have?

A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.

How much does it cost to replace a chain on a bike?

How much does a bike chain cost to replace? Entry level chains can start off around $15.00 with more expensive and higher performance chains ranging from $25.00 to $60.00 or more. More expensive chains increase shift quality and are generally more durable as they wear.

Are SRAM and Shimano chains interchangeable?

Shimano and SRAM 11-speed chains are cross-compatible. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturer’s recommend pairing your components for optimal performance.

When should I replace my bike chain?

If you are using a chain designed for ten or fewer gears, replace your chain as it nears the 0.75 percent mark. If you are using an eleven or twelve speed chain, replace your chain once it has reached 0.5 percent wear. For two-sprocket or single speed bikes, replace your chain as it reaches the 1 percent wear mark.
